Description: After the P6 port analog voltage input AD converter, from P4, P5 port to connect the digital output.
The use of multiple single-channel AD converter, collecting P6.0 input analog voltage value (range: 0 ~ 3.3V), converted to a digital value.
Establish two-dimensional array and draw back the voltage value through the acquisition sequence look-up table approach. Then displays the current voltage value through the digital, display
Show follows the input analog voltage changes. Since only two digital tube, it shows the voltage values are accurate to one decimal place, such as the current
Input voltage 2.37V, displays 2.4V. Available multimeter test shows whether accurate.
