Hello guys.I dont want to complain, but I think its not normal trying to spend 1 week to compile Demo projects for my STM32L4R9I-DISCO board. I have the github repo below, I've added StemWin libs which are not included due to license problems, but I ...

Hi, i am new to stm32 and i got the project to rotate stepper motor using stepper driver .

i am using stm32f103 controller with opto -circuit to rotate my motor . But my motor is rotating only in forward direction even if i make my direction pin SET or RESET . BUT i need to make my motor to rotate in both forward and reverse direction. Ca...

DMA CCR1 CCR2 conflict I can have signal on PB6 or PB7 but not both on one time. by changing CCR1 and CCR2 arrangement. CCR1, CCR1 =signal on PB6 CCR1, CCR2 = signal on PB7 CCR2, CCR2 = signal on PB7 CCR2, CCR1 = signal on PB6

Can the STM32 Power Shield (LPM01A) be triggered on AND off?

The X-NUCLEO-LPM01A Power Shield can be triggered by the target device to start acquisition, using the D7 pin. Can it also be triggered to stop acquisition?Also, my power shield is currently running v1.0.1. The latest version of the firmware is 1.0.6...
