 |
|
Bonjour
je cherche à connecter une carte microbit pour y accéder en REPL
pour cela je suis sensé utiliser le device ttyUSB0 mais aucun fichier de ce type n'est créé quand je la branche.
je soupçonne un module noyau ou bien une config de udev, mais jusqu'ici je n'ai rien trouvé de concluant
Merci d'avance

Hello,
Que dit lsusb ?
As-tu installé un pilote série USB genre FTDI ?
dans Device drivers / USB / USB Serial Converter

Non ce n'est pas résolu, ceci est l'état de ma machine au moment où j'ai posté ma question.

Ta carte se présente comme un dispositif USB-CDC, il se présente probablement comme /dev/ttyACMx (x = {0,1,2,...})
Que dit : quelques secondes après le branchement? |

Bonjour
A priori c'est résolu.
C'est ton message à propos de USB-CDC qui m'a mis la puce à l'oreille : en activant
USB Modem (CDC ACM) support
dans le noyau, j'ai bien un périphérique ttyACM0 qui apparait.
Merci beaucoup
