Yes, the algorithm is right and I'm programming my controller according to the aforementioned algorithm. No, you don't! This: cs=1;
intr=1; rd=1; wr=1; cs=0; wr=0; wr=1; adc=0x08; cs=1; adc=0xFF; should be: cs=0; wr=0; adc=0x08; wr=1; cs=1; adc=0xFF; And this while(intr==1);
cs=0; wr=1; rd=0; rd=1; cs=1; value=adc; should be: while(intr==1); cs=0; rd=0; value=adc; rd=1; cs=1; Kai Klaas |

| You must convert raw ADC reading into temperature | 01/01/70 00:00 | |

| Configured as push-pull? | 01/01/70 00:00 | |
