  1. Hello, I'm new to this form, looking for some help with the Dual H bridge PMOD DHB1. I connected my power supplier to J4, my motors to J5 and J6. I have a custom IP that uses switches to drive motor speed with most significant bits of a duty cycle for PWM output at 2kz. I also have 2 switches connected to the DIR1 and DIR2 respectively. I also have button 3 connected to a reset condition to initialize code, inputs and outputs. To help debug, I connected the EN1 and EN2 output of the custom IP to the board LEDs to confirm that the signals are working correctly. I also checked the voltage at EN1 and appears to be doing what I expect. However, I do not have any motor actuation. I checked the voltage at the J4 = 8V, but neither J5 or J6 have any voltage differential between M+ and M-. I checked the sleep and fault pins they are both high, which is normal behavior as they are pulled low when in sleep or faulted state. Any advice on what I can do to find an issue would be appreciated. Thanks, Dave HBridgeTOP Hbridgecode (1)
