A82c250 что за микросхема
Передавать инфу буду на AM3359 (ARM контроллер от Техас инструментс). У него есть апаратная поддержка CAN. Конкретную модель датчика сейчас сам не знаю.. Это автомобильный датчик, скорее всего аналоговый. Я не схемотехник =( поэтому только предположил, что аналоговый сигнал необходимо перевести цифру, затем передать его через интерфейсная микросхему (например PCA82C250) процессору AM3359. Где программа уже обработает сигнал и отобразит на LSD.
Разрабатываю бортовой компьютер для погрузчика. Сам программист, правда теперь и схематехнику нужно изучать(
