Flow of the main program. This flow contains the main tasks of the main. The basis is a tick time from 1ms via an interrupt routine. The required times are thus determined in multiples of 1 ms. Examples are the meter time of 200 ms, the shutter lag of 52 ms, etc. Only the Flash task is excecuted directly due to the short delays between 10 and a few 100 us. Flash power steps are 4 us resolution with a max of 1024 us for full power. Detail of the timings are on this picture:

During the software tests, every I/O pin from the Atmega328p controller is connected to the logic analyser, now 20 signal lines total. Any time relatrion between the signals can be seen.

Flow last update:
2012 Feb 15
All timing functions on logicanalyser are tested now. Corrected a few Flags and labels. The repaet mode is also tested and take an 3D picture every 278 ms if the detector send a detection signal ( near 4 pictures/sec) Higher is possible but I have limited this so even the wakeup sequence is correct from the first picture ( minimum 200ms wakeup if started from sleep mode). All lasers are disabled during shutter open time and IR lasers are only actieve if the record sequence is started (Start buttom actief) for security.

Display of the 3D setup 2010. Allmost functions works just now. The communication between CPLD and the 2 AVR controllers are tested. All bitstreams are transfert to the modules. Result, the LCD display show now all the information into the capture mode of the unit. The information into this mode is:

L166 : show the ambient light value
D00 : show the IR reflected light, here no object in focus so the value stay at 00
F2 : Show the numbers of samples before a fire shot. This works as a filters and can be set between 1 and 4 filter traps.
H03 : Sensivity level of the IR detector. This value is the trigger level for the difference signal between ambient light and IR reflected licht. The value can be set at 4 levels: 3, 6, 10 and 40.
S2 : slave flash steps offset now set at 2 and can be set between 0 and 4
M2 : same now but for the Master flashes on the unit, same range.
REC : show the capture mode, now the unit stay into REC mode and wait for a trigger.
V 7.60 : Voltage on the batteries. Here you now when you have to stop for low batterie level.

Other display information can be selected to adjust the flashes local and wireless. All flashes can be set between 1/512 pwr and MAX and each flash can enabled or disabled.
Backlight of the display is now on but can also set to off to lower the bat current.

The number of shots are also registered. To find the same picture pair, at start the 2 camera's counter are reset . So the same number give the same shot on both sides.

Next test are the mirros adjust procedure. Tomorrow I will adjust the hole unit and test it. On the logic analyser the camera signals are now correct at the output, The burst mode are set at 3 pictures/second if there is continue focus detection. If the detection falls, the unit can stay in burstmode if I want it so if there is again focus next few seconds the pictures are further taken. If I release the capture button, after the next infocus trigger the camera stop. If I push the STOP button, the unit goes direct into stop mode. All this functions are now fully tested on the analyser wave forms.

The logic analyser is one of my best tools. Without this tools it will take days and days to resolve your bugs. Now if there is something wrong a few seconds later you know where you have to change it. I have planned 1 week for the hole software, verilog code for the CPLD and assembler for the AVR controllers and this time is sufficient. So 15 March will be the release date as planned.

You need a big screen to have full controll over the hole unit during tests. Logic analyser, Quartus CPLD tools, AVRstudio for the AVR controller and the shema's. The logic analyser show the 40 usec samples from the IR focus system and the transfert of a serial bitstream of 44 bits to the AVR controller for general settings and display on the LCD.

Debugging of the setup 2010 3D unit.
Time for the final step. This picture show the debugging for hardware and software of the hole unit. On the picture the logic analyser (Logicport) is hanging up on the frame for security. 18 channels are available to measure all the protocols between the different modules. The STK600 on the left is also direct connected via the Jtag ISP for fast update ( take only a few seconds). On the top the USB connector goes to the PC for the update of the CPLD module hardware.

The hole test progress nice, I really hope to be ready on 15 March as planned. The unit is now powered via the batterie's but also if need via the mainpower. All the inputs from the front plate are tested and are ready. The IR laser signals, the IR detector, the LCD display etc.

The big I/O print is now ready for the 3D controller. This picture show the backside of the wirewrap print. As you see all my prints are wired manual with fine wires. This is a lot of work but you may change it easy. This I/O board is the global interface from the CPLD MAX II board. 88 I/O lines are avaible. The ATmega328p AVR controller is also on the print.

Now up to the final software. There are 3 modules, 1 for the CPLD board, software written into verilog code, and 2 AVR controllers software written into assembler. As planned I hope to be ready next week 15 March.

On the left side the 20 pins connector is only for debugging. The logic analyser can be connected to this connector. All signals from the CPLD board but also from the 2 AVR boards can be routed via this connector for analyse. Next week I will give some pictures of the debugging setup.

All software update is done via a USB link and take only a few seconds. Hardware debugging is realtime. The logic analyser is the Intronix LA with 34 channels at 500 Mhz. The software tools for the AVR controllers is the STK600 toolkit. All prints can stay into the setup during debugging or update.

camera synchro for 3D setup

Flowchart for camera synchronisation for the 3D setup.
I have only 2 different type camera's now so the timings are not the same. I just tested the shutterlags of the D200 and the D300. To test this, I have enabled the camera and via a digital delay and tested how long the delay is needed to have a picture. The camera's are set at F29, ISO 200 and 1/250 sec. The delay inclusief the delay for the wireless controller ( because the local and the wireless flashes need to go on the same time) is 52.5 msec for the D300 and 58.0 msec for the D200. There is a margin of 1 msec. This give me a delay between 57.5 and 58.5 msec.

To synchronize the 2 camera's I need to set the shutterlag to the longest delay of 58.0 msec . I need first to drive the D200 and 5.5msec later the D300 so there are exact the same time ready to have the flash window avaible.
This timings are delivered via the central controller. This way both camera's and wireless flashes and local flashes are all ready into the same short window.

With this values I can now setup my hardware to by sure the synchronisation is correct for high speed events.

View inside the electronic box. At the right side, the CPLD module mounted on the general interface board. This interface board is almost ready. The left side show the recent added keyboard interface and the switches. This board need to finish. All the I/O connectors are on this box. A few need to mounted on the bottom. (have to hold this connector this weekend from the store)

The top screen show the design of the big interface board on the PC. On the output connectors the flatcables need to be connected with the connectors on the frame. Here you see also how the alu box is optimalized for minimum wight. As much as possible parts are milled off. This electronic box can work stand alone. Power is on the backside via 10xAA batteries. On the CPLD board on the right side there are 20 test pins. This pins are only for diagnose via the logic analyser during hard and software update. I can bypass near all the signals from the CPLD and the AVR controller to this pins via software reconfiguration. This methode give me the possibility to wath even the SPI signals on the AVR controllers. This is very helpfull for a fast debugging of the hole unit.

The CPLD board can be updated via the USB connector on the top. The PC can give the current for the hole module in this case during the update. The AVR controller ATmega328p have a separate connector to the STK600 module during reconfiguration or software update.

The wireless RFM12B module stay on the general interface board and goes via a coax connector to the outside. This wireless module drive 4 extra flashes in TTL mode as background lighting. Flash power control of this remote flashes are done via one of the big buttons on the front panel.

The wireless system works on 868 Mhz and have a range of over the 50m. The delay of this wireless system is near 400 usec and adjusted to falls with the onboard flashes so they have exact the same startpoint at 1 usec precise.

Finally the electronica box on the 3D setup unit. All parts are foreseen. Now I have to finisch a few prints and connect all the wires to the setup like lasers,camera's,powerleds etc. But this can by done into the next 2 weeks. In the meantime the software can by adapted and tested. The 2x16 char LCD display is on the top (not to see on this picture). At night a backlight on the LCD show better the values into the dark.

To capture the insects in-flight I d'nt see the pictures on the camera's due to the in line position of the camera display's. But I d'nt need to see this camera pictures because the IR lasers take control of the focus position and make only pictures in focus. All the camera settings are manual, even the flash powers. I know if I take a picture at F29, ISO200 and flashpower at 1/32 pwr the lighting is good. The quick EV buttons let my adjust a few steps if the objects are very white or black. The focus distance is fix, so all this settings are only to adapt again if I change this focus distance. This change can only be done at home because the multiple calibration needed like the position of the mirrors, the IR laser beams the green laser beam and the extra 60mm macro lens with the photodetector and the build in AVR controller. The adjust of all this elements need a very precise regulation as the reflected IR signals are week. The IR detection is done in 40 usec, 1000 x faster then the normal camera shutterlag!

All the batteries are external on this frontside to replace them quickly. At night, the autonomie is about 3 hours. The weight of the total unit is now 8kg. This is only a little higher then the previous 2D version with one camera.

Front panelview for the 3D hardware box. In front the temporarily layout design. The most big part of the surface ( left side) is assign to the 10xAA batteries. the right side contain all the buttoms, switches, control leds and 2 big switches for the EV value adjust of the local and wireless remote flashes. On the bottom, multiple connectors must be placed.
As you see there are multiple holes. All electronic parts are into this unit

The electronics contain 3 big parts. The central unit is the CPLD board MAX II from terasic at 50MHz and is the most powerfull part. All timings for highspeed detection, camera synchronisation, flashes drive and wireless remote drive of the extra background flashes. The display unit and the local flash power TTL drive are provided via the ATmega328p controller. The IR detection contain a separate controller with the ATtiny45 chip. This controller measure in 40 usec if an object come in focus and give the information through the CPLD module. The sensivity level on the CPLD module determine if the camera's need to activated. The current version can also work in burstmode. If an insect stay longer in focus multiple pictures can be taken. I will test this and set the rate at 3 pictures/sec to start. But the camera's can shoot faster if needed.
There is also a timerkeeper chip, I need it to return in good time at home for the dinner. 4 extra AA batteries are added to work at night to drive the high power leds. The normal autonomy of the batteries will be near 4 hours.

The wireless build in unit can drive 4 extra remote flashes in TTL mode. The transmitter works at 868MHz, the european frequence range. The power of all the flashes are controlled into this central unit, even the remote flashes. A special knob let me quicly change 5 steps of 1/3 EV value just by a simple turn. This is helpfull by full white flowers or black objects. The camera's stay always into manual mode, there is no time to measure the environment light. The wireless unit is already tested to a distance over the 30m. But for this type work, the distance is max a few meter. This will help for better background.

I have planned 1 week to write the new program, verilog part for the CPLD board and assembler for the ATmega328p controller chip.I know this is very short but multiple parts are done before. The logic analyser help me to test all the hardware and the software and to readout the correct timings even at nsec level.

So the 3D setup is on on time as planned. Hope to be ready third week of March.

Update 2012:

High speed macro 3D portable unit with optical extern focus detector using 2 DSLR camera's and front side type mirrors.

First pictures of the portable 3D setup. The picture show only the mechanics parts. The electronic box need to added into the next days. This unit is realy difficult to make. There are a lot of fine pices to calibrate. The 2 camera's D300 and D200 are inline and can be adjusted direction mirrors. This is needed because the AF105/2.8D macro lenses d'nt have a fix lenght. The mirrors can be moved into the other direction on a slide. On top of this slide there are the 2 mirrors. They can turn a little to adjust for the keystone effect and to center the pictures on the frame. At the bottom on each side the IR lasers are mounted. The IR lasers can turn into X-Y-Z direction and are finetuned via separate screws. On the top of the unit the AF60/2.8D macro lens record the reflected IR lasers signal from the objects infocus. Into the body of this macro lens there is the AVR controller circuit to measure this IR light. This information goes to the central hardware controller for further action.
The 2 mirrors are protected for most of dust via the 2 nikon 62mm diameter filters. Just near this filters there are 2 powerleds to work at night. The 2 flashes are on the top and on both side there are the green lasers. The green lasers are used for me to point the unit to the objects. Even in full sunlight is see this green pointers. They are crossed mounted into the ideal focuspoint. The IR lasers are also crossed on this same point.

On the otherside I have mounted an optional calibration slide tool. See:
www.flickr.com/photos/fotoopa_hs/4351166539/

The testcard stay on this slide at the correct position and can be moved forwards and backwards. The textcard is used to calibrate the hole unit and to adjust them for the desired frame format. Moving the testcard d'nt change the high of the object, so this is a very helpfull tool to adjust and calibrate the hole unit.

The weight of the unit is near 8.5kg inclusief the electronics parts. This is very heavy to carry into the field but the results of this hightech detection system and 3D are so promising. I try now to cut down as many as possible alu parts to lower the wight. But the unit must stay stable. The load into the field is very heavy for all the parts.

Update 22 March 2010:
The setup is now ready and works perfect. Frame size is set at 100mm horizontal. Flash powers set in TTL mode at nominal value of 1/32 power. Pictures are taken at F29, ISO200, T=1/250. Burstmode set at max 3 pictures/second. The IR laser detection works perfect, need 40usec for the detection cycle. The detection signal goes from 10 units (black object) to 50 units (white object). The triggerlevel stay at 3 units, so all levels above this 3 units will give a trigger. I d'nt have an external shutter on this 3D version. The shutterlag from the 2 different camera's are 53.5 msec (D300) and 58 msec (D200). The controller synchronize this 2 camera's, first the D200 goes on and 58-53.5=4.5 msec later the D300. On the 58msec delay the flashes are fired. This time stay very constant over the time, all pictures are well lighted.

This interface board has a few adds now like the timekeeper chip so that I know when to go back at home, the temperature sensor chip as indication what temperatuur level for the insects, the RF transceiver module for the wireless flash control for background lighting, 2 powerleds are now also on this interface to see the insects at night (2x3W leds) and the extra AVR ATmega328p controller for the display but also for the local flashes in TTL mode. All the flashes are now controlled from my central keyboard module and have special knobs to fast adjust an EV value to the flashes if the flashlight need to be adjusted. One knob for the flashes on the frame and one knob for the wireless remote background flashes. In total 8 flashes can by driven by the controller, 4 local and 4 remote.

An extra row pins on the CPLD interface are used to connect to the Intronix logic analyser (LA connector). This is very helpfull to debug hardware and software, to capture all the timings and to make the correct documentation. This LA is direct connected to the PC in that case. An extra ISP connector connected to the ATmega328P make the update of the AVR controller without to remove the ATmegachip for reprogramming. The same for the CPLD MAXII board, the USB connector can by connected to the PC for the hardware update and reprogramming. There I can put new signals to the logic analyser connector to capture complex timings or errors.

The MAXII board have max 88 I/O pins. A few rows are now not solderd but the room to put this extra pins are avaible. This Terasic MAXII board cost only $69 but is very powerfull and superfast. The MAXII boad is mounted as a peggyback on the interface module. Pictures of this setup will follow once the interfaceboard is solderd.

Update to version 9.
Corrected a few lines and rename.

Blok diagram of the hole setup 2010. This diagram show the different communication lines between the modules. Central stay the CPLD module from Terasic as peggyback module on the global interface Board. This interface board contains now an extra AVR controller, the ATmega328P,The wireless RFM12B module for the external flashes, the realtime clock module and the temperature sensor. External there are the shuttermodule, the optical detector module and the central display module. All this lines are SPI lines at high speed (2 MHz). Electrical shemas are now ready, time now to make the PCB layout. Within 2-3 weeks I hope the have the PCB layout ready.
