Hello! I’m trying to control a Roboclaw 2x45 from an STM32f4, using packet serial. I converted the arduino library to work with my microcontroller and set the driver up in IonStudio. Here’s the problem: if i power up the roboclaw and my board, and try to send anything, the board doesn’t do anything(i am unable to read data from roboclaw’s S2 because i didn’t include an rx pin on my board when i was designing it), and no led’s are blinking. But as soon as i connect the board to my computer via usb, with IonStudio open, the driver starts working normally, and it continues to do so even if i unplug the usb. It stops working, though, if i power cycle the driver. What could cause this issue and what can i do to resolve it?
