LAUNCHXL-F28069M: Cannot read currents from BOOSTXL-DRV8031

Part Number: LAUNCHXL-F28069M


I use LAUNCHXL-F28069M with DRV8031 to controll one brush DC motor. I use DRV8031 like H-bridge and DC motor is connected between A and B. But I have problem with reading currents Ia and Ib from J3 pins 28,29 (ADCINA0, ADCINB0) from my LAUNCHXL. 

I use MATLAB/Simulink for coding and I use ADC block for reading with Hardware Interrupt in my block diagram. ADC is connected to scope but I cannot see anything in External mode.

I attach my Simulink diagram and settings of my blocks.

Thank you very much for your help.

P.S. Sorry for my english :)

  • Did you try and run one of the shipping examples?  Did that work?

    The best option is for you to contact MathWorks Tech Support for help on this. They may want to review your model to help figure out why external mode isnt working.
