I am new to STM32, and I am using a STM32L152c discovery board to run a sample blinking light program. I am using HAL_Delay to control the frequency of the blinking light. However, the frequency does not change when I change the argument to HAL_Delay...
7 years ago I made a personal project, which generates video via vga, now I would like to do it via HDMl, I have only found with fpga, but the code is not clear to me, I suppose it is vhl, or vhdl, but I would like to do it with stm32f0,will anyone h...
I've just tried on an 'L031 - after writing LSEDRV to 0b00 (using debugger), I can rewrite it freely to any other value, and the oscillator's behaviour follows the value written.Can ST please comment.JW
Hi everyone,I am currently migrating from STM32F303x to STM32G431x microcontroller (48-pin package) and started testing the GPIOs in reset state, without any firmware on-board. Also, there are no external HW circuitries connected to the pins (I meant...

Hello there,While I am trying to switch to dual bank mode (by making nDBANK =0) from default(single bank) mode of internal flash with STM32F765 controller, landing up in hardfault.After resetting from hardfault when trying to read nDBANK bit from FAL...
I am using F411. The sample code in F411 package can generate timer interrupt in terms of millisecond. I tried to play with some of the parameters like Prescaler, etc, but I could not make any difference. Can anyone give some advice on the relations ...
