Hi,
I stumbled upon the REMCU library and I'm intrigued. The idea is very nice, I have a lot of ideas how this could be used. Is it possible to connect multiple STM32 boards to one RPi using the library? If so, what changes in configuration should be done?
I haven't found an answer for this question regarding the library nor the OpenOCD. I believe it would be nice feature to be able to easily scale the system (I'm thinking about an industrial application of RPi with optional STM32-powered modules).

However, this is a precompiled library "community edition" with no (or partial) source code? could confirm if this is the case, or if I've misunderstood?

Is this project entirely open source, or not?

This is a good idea, it makes the raspberry pi much more flexible for sensor I/O. I've gone the MCP3008 route before to get analog inputs on the Pi. The link to the Blue Pill board is informative, no link to buy it. I don't see the blue pill board for sale on Newark. When I search ebay and amazon for stm32 blue pill several options do show up.
