M61541fp + PT2323 на Microlab H-600

null@example.com (Alex8674) — Sun, 23 Mar 2025 10:59:05 +0000

Восстановление Microlab H-600.
Отсутствие основного пульта, привело к изготовлению на основе Ардуино.
драйвера на процессор M61541 не нашел на просторах нета. Даташит на этот процессор сложный вроде 24 битный
Помогите в создании M61541.cpp &M61541.h.

При компиляции скетча выдаёт ошибку (Скетч использует 24824 байт (80%) памяти устройства. Всего доступно 30720 байт.
Глобальные переменные используют 1710 байт (83%) динамической памяти, оставляя 338 байт для локальных переменных. Максимум: 2048 байт.
Недостаточно памяти, программа может работать нестабильно.)

Здравствуйте нет ли у вас наработок по аудиопроцессору TDA7461d? Помогите пожалуйста реализовать управление громкостью аналоговым резистором или двумя кнопками на палате arduino nano. Имеется автомобильный усилитель kenwood из прошлого века, родную голову управления найти не могу, выбросить рука не поднимается, нужно ему дать вторую жизнь.
