Timer PWM arbitrary waveform repition counter does not work
Hi everyone,I am trying to generate an arbitrary PWM waveform using DMA burst write according to AN4776. It works in principle, except of one thing: If i want to have more than one pulse with a specifig period/pulse setting, the RCR should be used. H...
Flashing not happening using OpenOCD
I have created a new project in eclipse and have taken CubeMx configured files into my project and did relevant settings and able to build it. Now I have to flash it to my Nucleo-H743ZI2 board using ST-Link and OpenOCD but am betting logs like this a...
