Re: Callstack in Micropython

Yeah, that is basically what I want to do, but I want to execute several different python programms interleaved, i.e. I want to have several processes of python code, which can at any point in time give up the CPU-time themselves, by raising a certain exception, then I would like to store the Except...

Re: Callstack in Micropython

Hello. I'm currently looking into that, I found out, that with Pystack enabled the stack is located continously in memory, whereas with the stack-less option it may be scattered all over the place.

Raspberry Pi Port

Hello, I started porting micropython to the Raspberry Pi. You can find the current state in [1]. I had to do the following: in lib/utils/printf.c there were several occurances of a output-function probably used by the stm-port directly. I found the macro MP_PLAT_PRINT_STRN to be of more use here, so...
