Mixed day, got the 3 Atmega ic's loaded with the wt2.hex file with relative ease. I used the USBasp and burn o mat, which if I understand correctly runs on avrdude. After a bit of messing around, changing the driver, and the usb port I got it successfully loaded.
Then I did the high voltage tests and got 51 volts, 45 volts and 49 volts on the 3 mainboards. So what ever mistake I have made, I have made it on all 3.
I then went ahead and tried the shields. one of them gets 2 or 3 leds to light up. If it's 2, then its the middle 2 and they are white and green, if its 3 then they are all shades of blue, but different, one blue, one a bit purple and one turquoise. It did matter which of the 3 mainboards I attached it to, it worked like this. Not blinking, but solid for about 30 seconds, then a high pitched noise would start and after getting louder over 10 seconds, the leds would go out, the sound would stop and then they would all come on again and stay lit for the next 30 seconds until the noise started again and repeat.
the other shields would not light up.
So I spent 5 hours, checking the solders on the shields that didn't work, replacing some of the leds, even trying to resolder some of the pins on the TLC59401 SMD IC.
Bit frustrating, the feeling of making little progress after the whole day. Next move is probably to strip the two non working shields and re solder everything on again.
I don't mind having the assembly problems, I am learning something. It was my choice to take on a project beyond my skill level
