ADC Pin Configuration in C2000 Delfino 28379D

Dear Altair Community,

I hope this email finds you well. I am writing to seek your assistance and expertise regarding an issue I have encountered while configuring a C2000 TMS320F28379D development board for a project that requires seven sensor inputs through ADC pins.

The C2000  TMS320F28379D development board I am using provides ADC channels divided into three groups: ADC A, ADC B, and ADC C. Each group allows me to enable one ADC pin at a time. My project necessitates the use of seven ADC pins, but I am facing an issue when attempting to enable multiple pins within the same group (e.g., ADCBRESULT2, ADCBRESULT3, ADCBRESULT5).

The problem I am experiencing is that when I change the value connected to, for instance, ADCBRESULT2 on pin number 28 and monitor the other pins like ADCBRESULT3 on pin number 25 and ADCBRESULT5 on pin number 65, their outputs also change with the ADC value of ADCBRESULT2 on pin number 28. This behavior suggests that the ADC pins are not operating independently, which is crucial for my project's functionality.

I am unsure if this issue is due to a configuration error in my file or if it is a hardware limitation of the C2000  TMS320F28379D development board. Therefore, I kindly request your assistance and guidance in resolving this matter. If you have any insights, recommendations, or resources that could help me configure the C2000 TMS320F28379D development board to allow the independent operation of multiple ADC pins within the same group, I would greatly appreciate your support.

Your expertise in this matter would be invaluable to the success of my project, and I look forward to any advice or solutions you can provide. Please let me know if you require any additional information about my setup or the issue I am facing.

Please find the attached file.

Thank you for your time and assistance in advance.

Regards,

Sachith
