Добрый день.У меня такой вопрос,я нашёл в инете схему PICstep(www.fromorbit.com/projects/picstep/index.php),но там стоят дорогущие микрухи LMD18245.Возможно-ли процессорную часть оставить,а силовую заменить на более доступное,например L6203?

Нельзя, в LMD18245 много чего есть, чего нет в L6203: аналоговая часть - компараторы, ЦАП - для формирования микрошага. Схема потому и получилась такой простой на вид.
LMD18245 имеет смысл менять AllegroMicro 3979. Стоить будет дешевле, Пик не нужен.
