Ардуино lin шина
20 USDНужно написать код для ардуино опрос устройства по lin шине, устройство одно в шине
вот это я посылал в устройства
Serial.write(0x00); // а тут нужно 13 нулевых бит
Serial.write(0x55);// Байт синхронизации
Serial.write(0xC1); //ID
но поскольку у меня нет паузы в 13 нулевых бит устройство не отвечает.
какие данные в шине могу скинуть .
цена договорная.

Давайте попробуем
Как минимум с помощью хардварного UART-а вы это не сделаете (в AVR), но можно сделать через софтовый.
С радостью помогу вам

В чем сложность сделать синхронизацию кадра с помощью "дёрганья ноги"? А потом отправить 0x55 0xC1.
