STM32 MCUs products

New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

STM32H7R/S lines: 1st STM32 with bootflash and on-the-fly encryption

The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

Transfer time when using DMA and ADC

Hi, I am using a STM32F407. I programmed one channel of ADC1 to start on the falling edge of TIM8, which has a frequency of 100 kHz. So far so good, the ADC performs a conversion every 10 us (100kHz), measured with the HAL_ADC_ConvCpltCallback functi...

Resolved! Cannot get PWM to output on STM32L496AG Discovery Board

When I view the CNT register of the TIM8 structure during debug it does count up to 1000 before resetting. I am using PI6 of the discovery board (Discovery Board Manual). The pin does not output a pulse however I confirmed that the circuit works elec...

STM32L082 dual bank - set BFB2 bit is not enough?

Hello,I am looking for your help on how to use the dual bank mechanism on the STM3L082.My goal is to download the new firmware 'over the air' and write it into bank 2 (starting from 0x0801 8000)Bank1 always remains as it is (with original firmware)BF...

Hi Team Good Evening, I am using STM32H7A3 series Microcontroller for our project. How to set the sampling cycle for Direct, Fast and Slow channel? As per datasheet, Slow channel ADC Max Freq is 10MHz. Is Slow channel ADC works more than 10MHz?

Resolved! Low Frequency PWM measuring (0 - 4Hz) and trending readings with STM32F030

I am currently using an STM32F030 MCU's external interrupt to measure an incomming PWM signals Frequency, Period, Duty Cycle and Pulse Width. The incoming signal can be between 0 - 4.167Hz. This is working great, capture all three transitions in th...

Implement UART Transmit in DMA mode correct way

I am using stm32f779I eval kit. I am using example UART_HyperTerminal_DMA by en.stm32cubef7.I am trying to implement UART in DMA mode to transmit a simple string.So I have used CubeMX to generate the code and I have configured UART1 TX DMA in normal...

Resolved! STM32H7 FDCAN Goes to INIT when sending first message

I have a STM32H745 Nucleo and I am trying to get the CAN peripheral working. I believe I have everything set up correctly (bit rate, RAM etc) but when I call HAL_FDCAN_AddMessageToTxFifoQ() the first time the peripheral goes back to INIT. The next...

STM32 Read Protection And Rx-Tx pins

I've flash protection level-1 on my stm32f429. When I open the flash protection on my mcu and connect the serial prolific to read and send data under UART. My source code couldnt run. But if I remove the serial prolific's from the pins. And reset the...

Resolved! Ymodem protocole

I am looking this source codes to use Ymodem protocole,https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Projects/STM324xG_EVAL/Applications/IAP/IAP_Main/inc/ymodem.hBut I've a question about that, Line 65 says to us as in below:/* /-----...

Difference in Low power sleep mode and sleep mode in stm32l053?

I went through the examples on the ST site which have the direct implementations (not using CubeIDE generated code HAL for GPIO, SystemClock, ... config implementation)https://github.com/STMicroelectronics/STM32CubeL0/blob/master/Projects/NUCLEO-L053...
