STM32 MCUs Products

Want to discipline the RTC time with respect to UTC with the aid of UBLOX GPS module. what are the different ways I could do this?

1. Use 1pps as external interrupt and count the number of pulses of RTC clock, then use sub second shift feature of RTC.2. Supply the time pulse output of the UBLOX to the reference clock detection and configure the time pulse to be 60PPS and may be ...

I am using STM32F373CCT6. My application requires one timer to trigger another timer, whose output will be available on port pin. Is it possible? If yes how?

hi, I am trying to use it in the same pin for two different purposes. I'm setting 4 pins for SPI comm and after I finish using them as SPIpins I need them as normal gpio. I tried to toggle them with set and reset but didn't go so well. what should I do

for exmple, this is a part of the code:void DAC_AD5621_Write ( uint64_t DAC_Data){ HAL_GPIO_WritePin(dac_cs_GPIO_Port, dac_cs_Pin, GPIO_PIN_RESET);////Select SPI DAC_Data = (DAC_Data&0x0FFF)<<2 ; uint8_t DAC_Data1= (uint8_t)((DAC_Data>>8)&0x00FF); ui...

StdPeriph Driver canBUS (STM32f4) and HAL CAN (STM32f0) not working (SOLVED)

Hi everyone!I'm in a hurry, I have a canbus network working with stm32F4 without problems working in STD Periph drivers, and even I have 2 sTM32F0 working HAL Can with out problems (I'm gonna left the 2 config), when I try to conect both networks, th...

Does dual-bank read-while-write work properly in STM32L496?

My project uses dual-bank flash memory, bank 1 (0x0800 0000) for main code and bank 2 (0x0808 0000) for ota image and also allocated (0x080F F000) for saving the system setting. After switching bank (FB_MODE =1), the main code runs at (0x0808 0000) a...

Hello! Could you tell me, please, an info about the date code on 1.5KE Transil diodes? I read a datasheet but the column “Marking �? tells me only about the first string (Part Number). Maybe, there’s another document with more complete info about markings?

Talk to Flash in STM32L412KB without using HAL library

Hello everyone!I am trying to write to flash without using built-in HAL functions. Initially, I want "Hello World!". The Flash is only aligned double word writable as shown in the reference manual (RM0394) standard Programming technique Section 3.3.7...

Can TIMx_CNT value for STM323DF4 be reloaded on the fly?

I have a custom board design using a STM32F407. Timer6 is running in interrupt mode with a 42 usec period. I also have Timer7 running in interrupt mode with a 3 second period (upcount mode).Each time the Timer6 interrupt runs I reset the Timer7 TIM...

Help to add EXTI to a port already in use as ETR input for counter/timer (PA0).

I'm struggling to find a solution to this by searching.I have an existing system running using PA1 as an EXTI set up through Cube MX. I just need to add an exrernal interrupt to PA0As far as I can see the following code is all I should need to add...
