Lab #9
Lab Objective:
Write a Software for 16F88 to take Analog Inputs from the Port A0, A1, And Vdd
and take the digital output on Port B. Resolution of ADC is 10 bits and Clock rate ,
800000.
Write software for PC to take input from the Port B of 16F88 through PortA of
USB-1024LS. And show it to the monitor.
