--------------------------
на ADC0 подаю 1 вольт, питание 4.8
содержимое переменной при выполнении (adc_data) показывает (впротеусе)-> adc_dataL R-61168:R-61167 Item (2 bytes at 0xFFFF1110) not within memory block (0x00010000 bytes).
Я так понял значение выходит за пределы... как мне считать правельный результат???
