Description

This Board will eliminate control signals and even microcontroller and its very easy to use to convert any Analog to Digital output , with standard control inputs , its based on pic 16f72 ,This board is having 5 ADC channels , 1 PWM output , Using PWM its very easy to control speed of DC motor.

There are 3 Modes in this board

•   Analog to Digital Conversion.
•   Analog to PWM output.
•   Digital to PWM Output.
How to use

•    Power ON with +5V & GND.

Analog Input – Digital Output

•    Select the control bits for the respective analog channel required as in the table.
•    Get 8-bit digital output from B0-B7 pins.

For example

•    I had given 5-analog inputs. Now I have get the output of A3 channel.
•    Select control bits as C5=0, C6=1, C7=1.
•    So Analog Data given to A3 channel is converted to Digital output (B0-B7)

Analog Input – PWM Output

•    Select control bits as C5=1, C6=0, C7=1.
•    Give the analog inputs AN0 pin.
•    Get output from PWM output pin.
Digital Input – PWM Output

•    Select control bits as C5=1, C6=1, C7=0.
•    Give the 8-bit digital inputs to B0-B7 pins
•    Get output from PWM output pin.
