I am trying to generate high voltage pulses using STEVAL-IME013V1 but I could not manage so far. I applied;
VDD=5V DC
VSS=-5V DC
HVP=HCP_CW= 20V DC
HVM=HVM_CW= -20V DC
When I use USB cable, the boards turns on, lights work fine, all buttons work. However, when I used +/-5V to power the board, ligths do not turn on, buttons do not work and I cannot select any pre-programmed programs.
I do not know why board does not work with +/-5V to power but it turns on with USB cable.
Can you please help me on this?
