SP1ML: (re)programming it for no external uController need

Question asked by Alex Co on Jan 13, 2018

Hi all

I bought some SP1ML modules... It seems that their main reason is to be easely driven by external uController. However, I would like to trim my schematic and BOM and use the internal microcontroller both for I/O and to drive transceiver. I tried to search for some source-code libraries  or something but ST has just .bin firmware files.


Is it possible to do what I am planning to do? In datasheet we can read that SP1ML I7O pins are for future use. In case we can programm it with custom firmware can those pins be used for regular I/O.  Any source code available or instruction to do this?


Thanks a lot
