I'll document my progress on the InputTrigger/NissanTrigger Helper Board here.
This is my current table setup:
The chip is the AtTiny2313.
The (ugly) schematic:
(I didn't have a AtTiny2313 component for the schematic, thus the older AT902313 is pictured, but the pinlayout is the same.)
The code is [here].
It will light up the corresponding green LED. I've never seen the LED used for decoding errors light up.
I also need to output the trigger for the tachometer, but that's just copying the simple trigger output.
When removing the need for the extra tachometer functionality, I realized that I just had copied the InputTrigger/AudiTrigger, but without the two LM1815 chips.
TODO:
- Change output to simple trigger + cam sync
- Create a real schematic
- Get input on the solution
- Make a real board
- ?????
- Profit!!!
