Please help if you can, but please do me the courtesy of reading in full before replying: We have a product using STM32L475 with a 32768Hz clock on the LSE. When I attempt to tune the crystal oscillator to within the performance spec of the crystal ....
In the document UM1775 there is stated the following:"5 V and 3 V can be used as output power supplies when an extension board isconnected to pins P2 and P3....In this case, the 5V_O and 3V_O pins deliver a 5 V or 3.3 V power supply and thepower cons...
I'm using several Nucleo-H743ZI boards. At reset (reset handler) the bit ACTVOSRDY in PWR_CSR1 is 1 on one board and 0 on the other. 0 means "voltage level invalid, above or below current VOS". The current VOS is of course the default one at reset, i...
hi guys. I want to use DMA to change the PWM frequency in the pwm running. I used DMA to change the ARR of Tim, but it was failed. So how to change the pwm frequency by DMA?
Hi,I bought a STM32L476 board. I started with the demo available in keil uVision and it worked fine easily, but it is closed, you cannot modify anything.My question is: may I follow the MOOC with this board? instructions require a different specific ...

I made a small wav-music player with a STM32L452. Reads data from SD card via SD 1 bit mode, and plays it over the DAC. Homemade jukebox, fun little project.My problem is: while all the small cards (up to 8 gig) I tested are o.k, larger cards do not ...
I'm implementing two channels of DMA in my STM32F302x using Timer 2 in input capture mode. Do I really need the HAL_DMA_RegisterCallback callback function? I'm using DMA interrupt mode so each channel has a DMA1_Channelx_IRQHandler that performs the ...
I need to receive signal information in percentage %.How can I convert/change received information ?Thank you
