PIC16F15323 / ADC / sleep

[Admin HWnews]

Zde je celej zdrojak...

https://pastebin.com/y8MnmzR9

v podstate vsechno co pisete jsem udelal...

chodi mi timer6 z LFINTOSC 32kHz - preruseni jak ma byt po 1s

AD prevodnik take funguje...neni problem zavolat prevod...a dostat vysledek

jakmile zapnu autotrigger tak to jede jak splasene..tohle je ten vypis z 
preruseni:
