RTOS/MSP430F5529: Add external reference using ADC library

JLeon VP

Part Number: MSP430F5529

Tool/software: TI-RTOS

Hi,

I have a project in RTOS where I use the ADC.h library, the problem is that now for hardware requirements I need to add external reference voltages for ADC.
You could tell me how to do this, I was investigating a bit but I have not been successful.

Thanks!

Hello JLeon,

TI-RTOS for MSP430 doesn't have a specific driver for the ADC. You will need to set this up with either DriverLib or via register level access like in the example found in the following link.

Thank you very much for responding, I realize that the problem was even worse.
After reviewing this I have a question, how do I resolve the jump to the interrupt vector (ADC10_ISR) of the 10-bit ADC, I have no idea about this.

I understand that these interrupts are handled in the .cfg file, I have made these changes for uart, i2c and gpio but in this case it is not handled within RTOS.
I know that the interrupt vector address corresponds to 54.

I hope you can help me, thanks.
