Using the OSTC for eCCR

Post by Mark_none »

Hello,

I would like to use my OSTC to control a homemade eCCR I've planed. Knowing that a solenoid driver routine is not in the current code maybe you can give some hints about this?

Hello Mark,

To control an eCCR you'll have to modify some parts:
- The firmware of the O2 board so it drives the solenoid to keep your ppO2 within range. It's open source: Firmware of O2 Board and should be quite easy
- The hardware: The board does not have a solenoid driver circuit (Btw. What kind of solenoid are you going to use?). The board has some spare pads you could use to interface to a driver circuit. Or (better) built the board completely on your own and use the OSTC for monitoring only. The OSTC hardware can not drive a solenoid directly and _we_ have no plans to implement such a critical feature into the firmware, sorry.

regards,
Matthias
