How to generate a 22MHz square wave by using internal clock in STM32H743
I will like to generate a 22 Mhz square wave by using internal clock. I have tried to use TIM3 to trigger ON OFF a GPIO pin PE9 , but i only get 800khz ++ . Anyone can help?

Program not running in a STM32L052K6T, but debug is working
Hello, I'm having a problem with a board with a STM32L052K6T. I'm able to Debug, but I can't use the Run function.The board was designed by myself. The schematic Is attached at the bottom of this post. Using STM32CubeMX I have done a HAL, and import...
STM32 Lock up Issue
Dear All,We are using STM32407 and NXP K60 in our product with our bootloader issue is when our app region is completely erased and we try to jump to app code the stm32 gets locked completely whereas Nxp k60 handles this issue by its Cpu lock up mech...
Cannot build STM32Cube_FW_L4 (v1.13) TrueSTUDIO Demo Project
Hi,I'm not able to build Adafruit_LCD_1_8_SD_Joystick out-of-the-box demo for the NUCLEO-L476RG board and TrueSTUDIO 9.0.1 IDEI had to fix a resource name but it is not enough. Please, can anyone help me with this issue?thanks in advance,gaston
Is there a way to formally submit a bug in HAL / Stm32 hardware?
And get a proper tracking of the process of validating and correcting it? I have posted last week a bug with complete code, most of it generated but CubeMX with minor modifications to enable the comparator with interrupt. This blocks the MCU without ...
Uneven DMA SPI transfer
Hi,I am trying to control a lot of RGB leds at the same time through TLC5955 RGB SPI controllers/I have 11 of them daisy chained to my STM32F7. Each one of them needs 1 bit (0 for data transfer) and then 768 bits of data (96 bytes). As you can see da...
Read Out Protection
Hi.My code generation is almost done. I want to lock the code so that no one else can conveniently reach and use my code. I want that for future development to erase the code and reprogram it. I read some information provided by ST and I think I have...
[LWIP] Direct connection between peripheral and STM32 ?
Hello,I need to connect a STM32 to an ethernet peripheral that will send periodially an UDP frame on a specific port. I just have to listen on the port and handle the measure.Ethernet speaking, is there any problem or modification required to handle ...
How to properly use SPI communication in STM32L053 ??
Hello.I am working on a project and using STM32L053 board.For now, my goal is to create a channel of SPI communication, master & slave, an to test my code.I am using only 1 ST board which serves both as master and slave. I have defined all necessary ...
Resolved! Is it possible to configure TIM1, 2, 3 and 17 as both master and slave?
Purpose is to generate 4 mutually phase shifted PWMs. Regular master/slave mode will require 8 timers in that case (right?). So thought of using the following, if possible:TIM1 = master to TIM2, TIM2 = slave of TIM1 and master to TIM3, TIM3 = slave o...
