Я хочу в этот сгенерённый кубом код добавить, скажем свою функцию или в какую-то из существующих, которая установит адреса source, destination, сколько слов слать и установит DMA->CCR бит EN7 в единицу. Ну и хотелось бы, чтобы при смене канала ПДП мои вмешательства тут были минимальными.
единственное отличие, тут я включил PLL поэтому таймеру включил немного предделитель
Спойлер

А люди посмотрят и скажут: "Собаки летят. Вот и осень."
Поэтому использую SPL.
