STM32 MCUs Products

Resolved! Hi, I am using the STM32L072rz MCU. What GPIO configuration should I use for unconnected pins to minimize current consumption?

How to create a RTC Wakeup event to wake up the MCU from sleep mode?

I'm using a Nucleo L152RE.I've read the 900 pages manual multiple times but I still miss a clear view of what needs to be done to create a RTC Wakeup event. I read in the manual:"""To enable the RTC Wakeup interrupt, the following sequence is require...

STM32L031K6 - How to Store Variables in EEPROM?

Hello!I am new in STM32, forgot my stupid question...How can i store a variable in EEPROM or flash?I have a STM32L031K6 Nucleo board, and got my CC1101-868MHZ transceiver with interrupts to work.I receive a unique address over RF, and want to store t...

STM32L072 not receiving UART1 interrupt in Stop Mode

Hello all,I want to use STM32L072 in Stop mode. But, it should receive interrupt UART interrupt while being in the stop mode. It is not receiving UART interrupt while being in the stop mode. Can anyone please explain the reason and the ways to solve ...

Resolved! [Solved]Problem with Usart Irq

Hi at all,Sometime happens that usart2 irq freeze and HAL_UART_RxCpltCallback isn't called.From this moment I can send data (I use blocking instruction HAL_UART_Transmit), but don't receive any.When this happens, HAL_UART_ErrorCallback don't called t...

Does these two crystal need Cl load capacitor? ECS-.327-12.5-34R-C-TR for RTC and ECS-80-18-30B-AGN-TR 8Mhz

ECS-.327-12.5-34R-C-TR for RTC and ECS-80-18-30B-AGN-TR 8Mhz . do i need to connect the Load capacitor to it or they have inbuilt?I have stm32f103 series MCU!

I2C CLOCK CHOOSE SYSCLK AND PCLK1

HEY I am having stm32f767zi. As datasheet has mentioned it has 216MHZ CLOCK. NOW PCLK1 is 54Mhz max. So stm32cubemx has 3 option for i2c. SYSCLK , HCLK AND PCLK1. By default stm32cubemx selected pclk1 for i2c which is 54mhz. so can i use sysclk for i...

Migration issues from STM32F030F4P6 to STM32G030F6P6 regarding SysTick / ADC

We are building a Bluetooth analog sensor module using the STM32 and decided to migrate from the F-series to the G-series to take advantage of the reduced power consumption. However, things that were easily working on the F-series are not on the G-se...

Resolved! what is the crystal oscillator frequency of UART of STM32f103CB

Hi,I just read an article mentioned that micro controller will limit (or do smthing) to lower down the frequency of crystal oscillator to match the multiply number of 9600 for UART, is that right?So if I'm using PLL to boost CPU frequency from 8M t...

STM32H743 Parallel synchronous transmission with DMA and GPIO

Hi all,I have problem to get work stm32h743 as parallel synchronous transmission with DMA and 16bits GPIO and timer as clok. I need something like in Application note AN4666 but for H7xx.I'm using GPIO port E what is on AHB4 and it si D3 domain and...
