Dear STM Community,I've configured the SAI on my Nucleo-G474RE board by setting the protocol to "I2S Standard" and data size to 24 bits to communicate with an external 24 bit ADC. Further, the SAI works together with the DMA to fill the buffers. Here...
We have a battery driven system based on STM32G031K8 and a S2-LP for RF running from a CR2032.I use the shutdown mode to keep power as low as possible. System is done by a reed contact connected to a wake up pin.We want to find out, whether the batte...
Hello,I am making SPI DAC update function, and I could not get PG11 to output SPI1 clock. While if I switch to PB3 pin, all is perfect. (this is alternate pin for SPI1)If I toggle PG11 as GPIO, I get waveform so where is no short or something simila...

If I use 4MHz Crystal instead of 24MHz Crystal, what will be the value of CL1 and CL2 capacitor?
I want to be getting my characters , including the first one from uart at 115200 baud rate and use UART to wake up from sleep, how do I do this ? The sleep mode and low power sleep mode, with all gpios changed to analog no pull and all other peripher...
Hello, I'm trying to implement a datalogger using a 32F769IDISCOVERY. I would like to be able to create a .txt file, write information on it and save this file on the SD card available on the board. The problem is, I've tried a lot of things, even fo...
please do not be silent, dear inhabitants of the forum. I want to understand what the problem is. I'm trying to put the output into an active state using a master timerHRTIM_SETx1R installed MSTPER HRTIM_MPER==1000 HRTIM_MCR installed CONT P...
I am using STM32G491REI6 in the application of sinewave Inverter. The input of the Inverter is Battery. We have given provision of variation of input battery voltage from 96V to 192V. When the battery voltage is under 120V. Everything is going nicely...
I am using an STM32H743ZIT6, and attempting to have COMP1 generate an NVIC interrupt when INP2 is lower than 1/4 Vref_comp. To this end, I set the POLARITY bit in the comparator configuration register to "1", which successfully 'inverts' the "cmp1_ou...
