Hello,

I'm interested by the IoTPy project. The goal is to communicate with a custom USB IO board, and I want know if there's somewhere a doc which explains the commands of the SPF protocol.
I should say that I'm a bit lost in the ioboard.py code for now ...

If anyone can help me, it would be much appreciated.

Apologies, I finally found what I was looking for here :

Good news. I have successfully ported SFP for Atmel AVR devices (that means it could also be usable on USB Arduinos).
For now, it works. I managed to blink a LED from the WeIO interface.

I will work more on the project this week-end to get all the IO and PWM working. In meantime, if someone is interested by the project, just let me know!

Just curious what kind of modifications did you do to get SFP to work? It was written in general C with portability in mind, but was tested only on a few architectures.

Yeah Giedrus, your code is very portable and I have changed almost nothing, excepted the MemoryManager's part.
I didn't find the sources of this lib, so I simply replaced by MemoryManager_malloc by malloc, MemoryManager_free by free and so on . So far, it works. I don't know if it could generate edge effects. I'll see.
Can you tell me where I can found the sources of MemoryManager ? I'll try to integrate it to keep SFP unchanged.

Now, I have to implement all the functions for GPIOs, SPI, PWM, interrupts, etc. But this part is not directly related to the SFP library.
