commands - TiboLGH/solextronic GitHub Wiki
La communication avec les logiciels de controle a travers une interface RS232 ou Bluetooth.
Cette page decrit les commandes utilisees.
Les commandes sont celles de Megasquirt MSII decritent dans cette page. Les commandes sont un peu simplifiees en omettant le CANiD et table index, inutilises par Solextronic.
