STM32 MCUs Products

What to do if an LPTIM takes too long to wake up STM32L476 from Stop 2 mode for the first time after every reset when LPTIM1 is used as a Timeout wakeup unit?

I am using STM32L476.I want to enter the Stop 2 mode and use LPTIM1 as a Timeout wakeup unit.The code is written such that the LPTIM1 wakes up the MCU from Stop 2 mode after every second. The LPTIM1 takes too long to wakeup the MCU for the first time...

lin software on STM32F103 - Detecting stop bit errors

I develop an own LIN slave node software stack for the STM32F103RB. This stack has to pass all tests from the LIN Conformance Test (according to ISO 17987-6). This test is a customer requirement.Actually the software and/or the hardware could not det...

Enter and Exit Low Power Sleep Mode?

Hi,I have configured MCU in Sleep Mode, I have Configured SPI,UART and Some GPIO. and also configured Interrupt RTC. I have Wrote entering Sleep mode like,main(){  MX_GPIO_Init(); MX_LPUART1_UART_Init(); MX_SPI1_Init(); while(1) { Disable_Pheripheral...

Do you have example code or IAR project for spinning a stepper motor using the card X-NUCLEO-IHM03A1 with NUCLEO-F767 board ?

STM32G4 ADC clock

Hi, Most of the STM32G4 CubeMX examples configure the ADC clock as synchronous clock mode divided by two,and the AHB ADC bus clock as 150MHZ. If I understand correctly, the ADC clock would be 75 MHZ for this configuration. The problem is that STM32G...

hallo, I'm programming the STM32F072CBT6. In the programming "STM demostrator gui" screen I check the "after programming Jump to the user program" but after programming the STM32F072CBT6 remain locked.

With some other microcontroller it works propetrly.Why with STM32F072CBT6 doesen't works?

Current consumption of the STM32L4R9I-EVAL Board is too high (180mA/+5V without display)

i am testing the stm32l4r9i-eval board. I removed the Displays and run a small gpio test program. The board is powered over external +5V and i'm surprised about the power consumption of the board. The current at +5V is more than 180 mA.It fall down t...

STM32 I2C Multi-master problem

I'm seeing a problem which seems to be related to the one discussed here: https://community.st.com/s/question/0D50X00009XkgoYSAR/stm32-i2c-multimaster-hardware-bug In my case though I'm not using DMA, I'm just using interrupt driven I2C but the sympt...
