I'm trying to get the ADC to periodically read 2 ADC inputs with Harmony 3 on ATSAMC21E18A.
The ADC in harmony is configured as in the attached image - AIN6 and AIN7 shall be read.
When I do no automatic sequencing either pin can be read by itself.
On automatic sequencing it reads the first pin AIN6 once and from then on it's stuck to AIN7.
How can I get it to read both pins periodically?
ADC0_Enable();
ADC0_ConversionStart();while ( true )
{
/* Wait till ADC conversion result is available */
while(!ADC0_ConversionStatusGet())
{
// SERCOM1_USART_Write("X", 1);
};
/* Read the ADC result */
adc_count = ADC0_ConversionResultGet();
// SERCOM3_USART_Write(&text[0], sizeof(text)-1);
sprintf(txData, "ADC Count = 0x%03x, ADC Input Voltage = %d.%02d V \r\n", adc_count, adc_count,adc_count);
SERCOM1_USART_Write(txData, strlen(txData));
ADC0_ConversionStart();
SYSTICK_DelayMs(500);
/* Maintain state machines of all polled MPLAB Harmony modules. */
SYS_Tasks ( );
}
