Looking for information on the relay and PWM expansions
-
Still some questions:
- where can I find the C/C++ source code to drive the relay and PWM expansion
- and the schematics for these expansions, would be great to built my own expansions
thx

Hi @Johan-Simons, the source code associated with all of our expansions can be found in this repository: https://github.com/OnionIoT/i2c-exp-driver. The PWM expansion source code is in this file: https://github.com/OnionIoT/i2c-exp-driver/blob/master/src/pwm-exp.c.
We haven't had a chance to organize all the schematics yet. We will be doing that in the new year. Please stay tuned!

Great, I'll have a look at the code.
thx
