I´m using a stm32f4 discovery board, and when i try to connect it to my computer it show "No ST-LINK detected". I don´t know if there are specials drivers for windows 11.
DAC Exercise in STM32F4xx
Good evening everyone,today I generated a sine wave (using array method, 80 samples per time period) and got it on oscilloscope using DAC channel 1. Then I tapped this analog wave into the ADC of the board. Then i again converted the data from ADC ch...

Resolved! Nucleo-64 STM32L452RE Issue SPI MISO
Hello, I'm a little confused about the SPI communication. I tried to get the MCP2515 working with the STM32, but I end up at the beginning because I can't read data from the SPI. Both the HAL_SPI_TransmitReceive and HAL_SPI_Receive functions give me ...
Demo boards with Micro SD slot that uses standard SPI instead of Quad SPI?
Hi,which STM32 dev kit (preferably STM32L4 family if available) has a MicroSD card reader that uses standard SPI (i.e. not Quad SPI)?Also is there a selection tool that allows you to specify the type of SPI or at least whether it has Micro SD? Thank ...
Resolved! Initial flashing stm32g474 without debugger/programmer
For the STM32G47xxx microcontroller, the transition to the system bootloader is fair by changing the optional bits or by transitioning from the user space. Setting the required optional bits forces the use of a programmer and something like St-Link U...
Resolved! STM32 DOESN'T WORK AFTER EXITING DEBUG MODE
Hello,I’m not sure that is this important, but the board I’m using is the STM32F413ZH. When I try running an application on the STM32, it generally works fine, but sometimes after exiting debug mode, it stops working. Actually, this isn't a big probl...
I use the nucleo-f446re board and this part gets very hot.
When I connect to my computer with a USB connection to upload the code to the nucleo-f446re board, that part of the board gets very hot. I didn't forget to jump to the U5V all the time when I connected to the computer with the USB. Why does this happ...
