The example shows sampling by an AD converter and sends it as a text via UART1. The realization is carried out by using the mikroPascal 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.

program ADC_test; var adcRes : word; txt : string; begin TRISB.10 := 1; // set pin as input - needed for ADC to work Uart1_Init(9600); while TRUE do begin adcRes := Adc_Read(10); WordToStr(adcRes, txt); Uart1_Write_Text(txt); Delay_ms(50); end; end.
