bypass HAL fro spi dma transfer

Hi I'm looking to possibly skip the HAL overheads to sent an SPI DMA transfer. basically I want to do this   HAL_SPI_TransmitReceive_DMA(&hspi5, (uint16_t*) &data_to_send, (uint16_t*) &FromTheADC, sizeof(data_to_send));without the HAL overhead that s...

Will our EMC testing be impacted if we change from STM32H747I-DISCO to the STM32F769I-DISCO?

We succesfully passed the EMC testing (IEC 61010-1-2) in our product with the STM32H747I-DISCO. Due to shortages on the market, we would like to use the STM32F769I-DISCO instead. Will this affect our EMC test results? And if so, why would that be?

Hello, We have implemented MDIO(Management Data Input/Output) protocol by bit banging in the STM32 Nucleo-L series board and the corresponding frequency of MDIO is 2.8MHz as of now.

My requirement is to increase this frequency since the MCU (Arm® Cortex®-M33) operates at 110MHz. Kindly, share your inputs ?

RTC wake up timer is not waking up MCU from the STOP mode

I am using STM32F091RCTx microcontroller and have configured RTC internal periodic wake up timer in interrupt mode. On timeout the respective isr routine is getting called but it is not waking up the MCU. i am not using SLEEP_ON_EXIT.Can anyone help ...

Hi, I would like to understand if the board B-L462E-CELL1 includes the iSIM technology. I read that it includes the SONY chipset ALT1250, which, according to the specs should include the iSIM but I cannot see it anywhere in the ST board specs. Any help?

Freertos low Power Run mode

Hi guys, I use stm32L4 and freertos, I try to make low power run mode in my project. Normally my mcu works 60Mhz but I want to reduce clock as much as possible in low power run mode like 1Mhz and I want to use freertos in low power run mode. I change...

Sometimes LPTIM2 does not start when using one shot mode. I see this happened 4 years ago to another user and their question went unanswered. So I'll try. (STM32L4R5ZIT6)

// Code to start the one shot timer void set_delta_alarm(Long t) { LL_LPTIM_Enable(LPTIM2); while (0 == LL_LPTIM_IsEnabled(LPTIM2)) ; LL_LPTIM_SetAutoReload(LPTIM2, t); // * TE_SECOND / ONE_SECOND); LL_LPTIM_ClearFLAG_ARRM(LPTIM2); LL_LPTIM_Star...
