Hi,
I am using Tivaware library for ADC module in TM4C1294kcpdt. I have requirement of using external reference voltage 2.5V in my board.
So using below API, I tried setting external reference voltage and I am supplying 2.5V external voltage at pin VREFA+.
ADCReferenceSet(ADC0_BASE,1); // external ref voltage
But result I am getting is with respect to 3V reference voltage, so can anyone let me know whether any other configuration is needed for using external reference voltage?
Regards,
Supriya
