Hey there Sebastien :-) NuttX is so well organized that writing bare C here is far more efficient "rapid prototyping" so I had no more need to use MicoPython as it turned out memory hungry for bigger applications.
But still I am fan of Python so we could resurrect the idea :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info On Fri, Feb 9, 2024 at 4:04 PM Sebastien Lorquet <sebast...@lorquet.fr> wrote: > > Hi, > > I think I may like to have micropython work again on NuttX. > > Where can I find the latest efforts on this project, to try my hand on it? > > Sebastien > > > Le 26/10/2021 à 04:16, Tomasz CEDRO a écrit : > > On Mon, Oct 25, 2021 at 7:45 PM Xiang Xiao wrote: > >> On Mon, Oct 25, 2021 at 11:37 PM Tomasz CEDRO wrote: > >>> On Mon, Oct 25, 2021 at 4:44 PM Alan Carvalho de Assis wrote: > >>>> Hi Tomasz, > >>>> MicroPython was integrated in NuttX at some time ago, but it started > >>>> to crash and was removed. > >>> Yup, I saw some websites stating it work here but I could not find > >>> among interpreters.
