MSPM0L1306: ADC Output code monitoring

Mohit Vakharia

Part Number: MSPM0L1306

Hi team,

I have connected the MSP Microcontroller externally to motor driver DRV8705H and using it to monitor the current value (from the motor driver). I need to see what the value of the output code is from the ADC. In the GUI of the motor driver + MSPM0 there is no option to see the value of the output code of the ADC. Is there a way to program the SDK from the CCS or any other alternative way to get the value of the output code?

Regards,

Mohit

Hi Mohit,

You can try to see this value (ADC peripherals) in debug mode:

Thanks!

Hi Johnson,

In the debug mode, I found the register (screenshot attached) but it seems like it is not updating real time value. Should I take any further steps to watch this value ?

Hi Johnson,

it has worked and I am able to see the values quite nicely. My next step is to calibrate the whole system.

I mean I want to change the formula by which the ADC works for converting the Analog voltage to Digital value.

Is it possible to change the firmware of the Motor driver or is it possible to run a code in the CCS with the changed formula to get the result? If possible can you provide any example?

Hi Mohit,

Which firmware? I think change ADC Code to actual voltage should not a difficult task.

Thanks!

Hi Johnson,

the firmware is drv8706s-q1evm-gui-firmware. I would like to change it.

Hi Mohit,

Got it, we also provide some example code in MSPM0 SDK, maybe can help for you.

You can enter MSPM0L1306 main page and find this sdk.

Thanks!
