Other Parts Discussed in Thread: TMDSDOCK28335
Hi there, I've been having troubles with the ADC module on the F28335 microcontroller. I've run the adc_soc example and the output values from the ADC have no sense at all. The input signal is a 50 HZ, 2.8 Vpp sine wave. The output values looks like that (both channels converting the same input):
