TMS320F28379D: TMS320F28379D adc reading

Part Number: TMS320F28379D
Other Parts Discussed in Thread: TMS320F28069M

Hi, I am trying to read ADC with TMS320f28379D launchpad. I am testing ADC channels by connecting potentiometers JP1, JP2, JP3, JP4, JP5 ON - JP6 OFF and connected to PC via USB. With the help of the MAtlab Simulink scope, I can see the bit changes without any problems. But in the case of JP1, JP2, JP3 OFF - JP4, JP5 ON- JP6 OFF, when I feed 3.3 V to J1 connector and GND to J2 connector and connect the potentiometer to the ADC channels, I can't see the bit changes. When I do the above experiments with the TMS320f28069M launchpad, I can read the ADC channels without any problems in both cases. What could be the reason for this? Thanks in advance.

    Hello Bilal,

    Do you mind showing me how you set up the ADC in your code? Also, can you tell me which ADC pin's you're connecting to? This would be in the format of ADCINA0, or ADCINB6, or something similar. This makes it easier to check the connections in the manual.

    Best regards,
