Ok

ADC12 настроен на измерение последовательности каналов, однократно. SREF = 000 VR+ = AVCC and VR− = AVSS.
Последние четыре канала ( ADC12MEM12 - ADC12MEM15) подключены к GND ( см. datasheet slau144e page 21-3 ).
Вопрос: почему я не наблюдаю ноликов, как в ADC12MEM7 ( подключен на землю ) или где я не прав?
