This morning, the new PCB corrected has been sent in production.
All day, This morning I worked on communicating through serial on USB. But this was before the discovery of the cursed erratum concerning the ST32L. (Imagine tragic music). And then we realise that the intern pull-up was not functioning and that the PCB need a patch for this.
For now on, the USB still doesn’t work, but we have promising signs with the patch.
See you tomorrow
