Hi Community,Short version of the question: How can I achieve a response like shown in the first picture from the slave device, without getting stuck in an error. This response is from the specific slave device, but I can only generate it once. After...

Cannot connect to Board anymore

Hi,i designed a board with a STM32F030 and already flashed and debugged it with success. However i used a Nucleo Board in order to flash it and I cannot connect to the target anymore. I also want to mention that i used the regular ST-LINK V2 as well....

ST32Cube_FW_H7 V1.5.0 Nucleo H743Zi code for LED2 doesn't work.

I used ST32Cube_FW_H7 V1.5.0 Nucleo H743Zi example code for Nucleo H743Zi, the LED2 doesn't work, I thought I got bad module, then I order again, second Nucleo doesn't work too.

trouble with stm32f334r8 ADC which goes in to the unknown state in very weak noisy environment.

I am using stm32f334 in a power conversion project.I have configured its ADC in  independent mode and transfer its data by two channel DMA.some times in a even very weak noisy environment the ADC goes into the unknown state. I checked all of its regi...
