STM32 MCUs Products

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...

Is there an official way to create my own stlink debugger? I have schematic for stlink but I dont know how to program the mcu so that it can be used as stlink debugger
