I am building a software stack on top of a Debian OS/kernel, which handles communication as well (BT and raw sockets). I am currently working with the Raspberry Pi (and BeagleBone), but I need a new microcontroller since the Raspberry Pi lacks certain key features. My requirements are:
- At least 40 GPIO pins; out of which at least 8 analog pins.
- A microcontroller or development board that supports Debian.
- Preferably has built-in WiFI and BLE support, or supports shields for the same.
Conversely, recommendations and/or links for building an own stack based on an ARM CORTEX would also do. I'd appreciate any recommendations and/or links for the above.
