8.2 Transmit the Results

The ADC result will be read. If the result is under a specific threshold, the LED will be turned on. Otherwise, it will be turned off. Then, the conversion result will be transmitted through USART, as presented below.

while (1)
{
    while (!ADC0_resultReady());
    
    if (ADC0_resultBelowTreshold())
    {
        LED0_on();
    }
    else
    {
        LED0_off();
    }
    
    adcVal = ADC0_read();
    
    /* Transmit the ADC result to be plotted using Data Visualizer */
    USART1_Write(START_TOKEN);
    USART1_Write(adcVal & 0x00FF);
    USART1_Write(adcVal >> 8);
    USART1_Write(END_TOKEN);
}
