Hi, I am controlling digital discovery through Matlab but have two problems: 1- The voltages of output digital pins are 3.3V but I need them to be 1.2V. How that can be done in Matlab? I can set them to 1.2V using Waveform but as soon as I close that the voltages are back to 3.3V. I think I can run python codes inside Matlab but do not know what I need to run to set them to 1.2V. 2- the digital discovery has supply voltage pins VIO. But when I check them with the multimeter, they are all 0V. How can I turn them on through Matlab? I can turn them on in Waveform but not in Matlab. Not sure why their default state is off! Matlab add-on toolbox is great but unfortunately has very limited functionality.
