Example 4 – Operating an AD converter

The example shows sampling by an AD converter and sends it as a text via UART1. The realization is carried out by using the mikroC compiler for dsPIC30F microcontrollers. Fig. 13-4 shows the connection of a dsPIC30F6014A microcontroller for sampling the voltages of the sliding contact of a potentiometer connected to the pin AN10 and sending it as a text via UART1.
