Description: 1, the experimental circuit shown in Figure 38. Potentiometer through the lower left corner bench RW1 0 ~ 5V DC output voltage into the ADC0809 Channel 0 (IN0), using the output of debug command to start the A/D converter, enter the command to read the conversion results, verify the input voltage and the converted number relationship. Start IN0 start the conversion: Out 0298 0 read the conversion result: In 0298 2, programming acquisition IN0 input voltage, the screen shows the converted data (16 decimal).
