Hello,
I am using the EVLSERVO1 board and trying to monitor the DAC outputs with an oscilloscope, since the high-frequency plots in Motor Pilot are difficult to use effectively. I enabled DAC Debug in the FOC Wizard, assigning DAC Out 1 to PA4 and DAC Out 2 to PA5. After doing this, I checked CubeMX and confirmed that these pins are configured correctly.
According to the EVLSERVO1 schematic, it looks like I should be able to connect the oscilloscope probes to pins 8 and 5 on the J2 connector. However, when I select a variable to output to the DACs from within Motor Pilot, I see no signal on the scope, just noise.
Is there anything else I need to configure to get the DAC output working?
Thanks
