Hi, that's great. I don't mind adapting it for NuttX. I think it could be made to have a hardware dependant lower-half to abstract the calls to GPIO handling.
The part I'm unsure about is the licensing. If it is based on some code you cannot identify I think it would not be possible to include it unless we know the original license is compatible. Do you think you can identify where it came from? (maybe by googling a piece of code or comment) Best, Matias On Mon, Jan 18, 2021, at 15:12, Fotis Panagiotopoulos wrote: > Hi, > > I do have one. > It was designed to run on STM32F103s where the I2C peripheral has some > errata limitations. > I have used it extensively on many projects without any issues. > Although I used it only for "simple" transfers of just a few bytes, I don't > see any reason it wouldn't work in any other scenario.
