Installer sdcc<\/p>\n\n\n\n

$ apt-get install sdcc<\/code><\/pre>\n\n\n\n
Copier un exemple et l’utiliser comme base (le Makefile pointe vers un Makefile.include qui contient le n\u00e9cessaire pour compiler vers le MCU cible).<\/p>\n\n\n\n
Flasher le code<\/h2>\n\n\n\n
Le MCU contient un bootloader USB, activ\u00e9 en connectant D+ au +5V \u00e0 travers une r\u00e9sistance de 10kohms \u00e0 la mise sous tension.<\/p>\n\n\n\n
Utilisation de ch552tool : <\/p>\n\n\n\n
$ sudo python3 ch55xtool\/ch55xtool.py -f FIRMWARE.bin -r<\/code><\/pre>\n\n\n\n
Execution en root n\u00e9cessaire. Crash apr\u00e8s la programmation si l’option \u00ab\u00a0-r\u00a0\u00bb (reset avec flash) est utilis\u00e9e, \u00e0 cause de la d\u00e9connexion du device cible.<\/p>\n","protected":false},"excerpt":{"rendered":"
