Брал шаговики и драйвера в дельта-крок, хотел попросить у них схему, но ни маил ни официальной страницы нет, драйвер DSM-2.5V3 , там стоит микро контролер вместе с микросхемой а3977, как бы упростить схему и избавиться от контралера, он тоже сгорел, а3977 вроде сама все умеет, может есть у кого рабочая схема на а 3977 ?
Вопрос снят, сдесь есть тема по этой микросхеме
