#103579 - Use ADC clock Responding to: ???'s previous message |
Instead count the ADC clock by using the gated mode of one of the 89S52 timers, busy of ADC will be the gate. Subtract the counts of the integration phase (10000 cycles)and you have the data. Of course you will have to read the sign and OV etc to complete the picture. |
