ESD diode protection on NJTRST (JTAG net) causing problem on power up the STM32F746IGT6 MCU. Anyone knows why?

Hi,We are using STM32F746IGT6 MCU in our circuit and it seems that when i connect ESD diode to to NJTRST/PB4 pin for protection, the MCU FW sometimes works at power up and sometimes don't (very random).It happens to me so far with two different ESD ...

Hello evryone i want to ask what is the difference between ADC_DMAConvCplt and HAL_ADC_ConvCpltCallback because they both give me an interrupt in the end of conversion when i az using DMA with the ADC peripheral

Can I use the STM32L476RET6 with TFT LCD?

Hello, I am making a module using  STM32L476RET6 .I have a few questions. ​In various examples, ​most of them use DOT-LCD.​ Can I use the STM32L476RET6 with TFT LCD?​ 2. If it is available, Can I connect 'LCD DATA' to 'LCD SEGMENT ' pin?Thank...

Using two channels in one ADC at a time.

SPI communication STM32F429ZI and L3GD20

Hello,I am trying to get started with gyroscope L3GD20 on discovery board. I had problems with HAL SPI library so I wrote my own. When I try to communicate with gyro I cant get any answer, I try to read WHO_AM_I register but all the time I got answer...

Problem reading multiples channels on ADC on STM32F303.

Hello,I'm new to STM32 world (but I know a little about MCUs...) and I'm trying to read several channels on ADC on STM32F303 MCU. I've tried to follow tutorials from Internet, but none of them seems to use version 5.0 of CubeMX, which may lead to inc...

STM32F746G Discovery board as ST-link programmer for external STM32 MCUs

Hi everybody,does anybody experience at using ST-link in STM32F746G Discovery board for external microcontroller? There is a ST-link connector (CN8) on the board with 4 signals - 3V3, CLK, GND, DIO. Problem is that there is not any possibility to dis...

HAL "instance" parameter contradiction

Hello,Is "instance" used just for numbering of HAL instances, or is it that the number has additional meanining in term of hardware ? For example:With SRAM, the instance in the SRAM example (stm32h7cube) is:hsram.Instance = FMC_NORSRAM_DEVICE; hsram...
