External voltage reference enabling for LAUNCHXL-F28379D, in Simulink, Embedded Coder Support Package for Texas Instruments C2000 Processors library

Hello everyone,

I'm facing a problem using a Texas device instrument and Simulink. I would like to acquire two channel (two differential voltages), using two 16 bit ADC blocks by the "Embedded Coder Support Package for Texas Instruments C2000 Processors" library.

I would like to change the Voltage High Reference (VREFHI), I saw that for many Texas devices there is the following option "Use External Reference", but for my device (Texas F28379D LaunchXL) not :(.

I was wondering if Have you faced with this problem and how did you solve?

How could I set VREF externally in Simulink?

I saw in device documentation that I should enable the voltage reference option, selecting the bit n 5 in the ADCCTL register (ADCCTL1[ADCREFSEL] bit), but

I don't know how I can change this value in Simulink.

Thanks a lot

Hello Edoardo,

did you find a way in the meantime?

If so, I would be very grateful for the solution

Best regards
