in my quest to try to minimize power consumption, i have been reading about, and watching videos about, things to turn off in the tiny. well i decided to start with turning off the ADC. just the ADC. other things to come later. i inserted this code into a simple LED blink program :
#include <avr/sleep.h>
#ifndef cbi
#define cbi(sfr, bit) (_SFR_BYTE(sfr) &= ~_BV(bit))
#endif
void goToSleep(void){
ADCSRA &= ~_BV(ADEN);}
loaded it and ran it. the blink still works. but my current draw after is the same as before. my question is, how can i tell if i actually shut off the ADC ?
