Неужели никто не использует мотороллеры?
Ведь контроллеры у моторолы весьма интересные:
- Куча различной периферии.
- Варианты на любой вкус.
- Есть бесплатные средства разработки (asm).
- Сравнительно дешевые средства отладки/программирования (~ $200-300)
Вот пара ВЕСЬМА интересных на мой взгляд однокристалок
