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, thus the older AT902313.)
The code is [here].
It will light up the corresponding green LED. I've never seen the LED used for decoding errors light up.
Todo:
- Integrate a LM2917 chip (for the tachometer)
- This doesn't seem to work properly. If I tap the signal with the LM2917 chip, the trigger won't work. Probably changing the electric levels with the chip connected.
- Can anyone think of another way to get the tachometer output?
- Change output to simple trigger + cam sync
- Get input on the solution
- Make a real board
- ?????
- Profit!!!
