hi when i use normal configuration for define this pin(PB4 in STM32H743) as GPIO output a problem occurs in the program.This pin is connected to the JTAG port and i use only SWD mode and pull up this pin by 10k to VCC.plz help me to config this pin a...
Hi,I have two questions regarding STM32H750:1) I would like to pre-burn its internal flash with a simple code that enable XIP (execute in place) from external SPI flash and jump to some initial address on this external flash. Then I like to permanent...
I am sending a fixed-sized buffer (512 byte) at 8 Mbits/s via UART out of an STM32F3, and I am experiencing what it seems to be a fixed delay (~ 2-3 bit periods) between consecutive frames. In the screenshot below, after sending the dummy value 01010...
We are starting (difficultly due to the lack of devices) the pre-production of our system built around an STM32 H743VIT, and, on already two systems (out of about 50), we have failures initializing ADC 2. For the first one, replacing the MCU was succ...
I've got a STM32L053 (on a Nucleo-Lo53R8). I'd like to drive TIM21 from the 32KHz clock, and gang it with TIM22 to form a 32 bit counter. But I'm confused on a few points.First question: how to drive TIM21 from 32KHz? The documents (RCC chapter, 7.2....
The problem is as follows: When I am trying to update HRTIM master timer registers (MPER, MCMP1-4) on the STM32G474 via Burst DMA access, every data word I write into the BDMADR register gets written into two of the specified master timer registers. ...
I came across a problem exactly described by this erratum: As you can imagine, this was "fun" to investigate.You may ask, "But Jan, don't you know you should read the Errata first?". Problem is, this is ES for 'G0B1, whereas the problem was observed ...
I was working on a simple SPI transmit code, I am transmitting some string data via SPI Half duplex, the code is like I press blue button on the discovery board, and it transmits data, which I read from logic analyzer, but every time after data is tr...
The function is supposed to read the I2C in non-blocking mode.However - quite often - it blocks the MCU for like 2 seconds!As I need to read an I2C in time critical part of my program, this breaks everything.I investigated the function source and I f...
