Próbuję zrobić prosty termometr na AtMega88, lecz nie chce on działać
Wypisuje wyniki z kosmosu
Połączone jest to tak:
Czy wie ktoś co jest nie tak?
Kod LM35.c:
[syntax=c]#include "LM35.h"
LM35Temp temp;
void ADC_Init(void) {
ADMUX = (AREFS1 << REFS1) | (AREFS0 << REFS0);
ADCSRA |= (1 << ADPS2) | (1 << ADPS1) | (1 << ADPS0);
ADCSRA |= (1 << ADEN);
DIDR0 |= (1 << ADC1D) | (1 << ADC0D);
}
uint16_t ADC_Read(uint8_t channel) {
ADMUX = (ADMUX & 0xF8) | channel;
ADCSRA |= (1 << ADSC);
while(ADCSRA & (1 << ADSC));
return ADCW;
}
uint32_t generalProlog(uint8_t CBase, uint8_t COut) {
uint32_t VBase = 0, VOut = 0, result = 0;
for (uint16_t i = 0; i < 1024; i++) {
VBase += ADC_Read(CBase);
VOut += ADC_Read(COut);
}
if (VBase > VOut) {
result = (VBase - VOut);
temp.underZero = 1;
} else {
result = (VOut - VBase);
temp.underZero = 0;
}
return result;
}
LM35Temp * LM35_readTemp(uint8_t CBase, uint8_t COut) {
uint32_t result = generalProlog(CBase, COut);
result = result >> 5;
result = (result * WSP10) / 1000UL;
temp.temp = result;
return &temp;
