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...
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...
Hi! We Use STM32F411RET6 IC in our device. When the device is in the factory, STM32F411RET6 can burn the program and run normally. However, in a few weeks, approximately 40% of chips will experience abnormal operation. When erasing the chip, the fol...
Colleagues,Here’s a code snippet which changes the state of two GPIO lines with delays in between.[My actual firmware has more code, and I’ve reduced it to this condensed example which still has the issue.] HAL_GPIO_WritePin(LED_DRIVER_ENABLE_GPIO_Po...
Hello, I'm working on a project using the STM32L412RBT6P microcontroller, and I have a few questions regarding the use of the VDD12 pins to achieve the lowest possible power consumption. 1. Can I directly connect the two VDD12 pins to a 1.25V supply?...
Hello,I am trying to setup clang (and later clang-tidy) in a project. To test clang integration with STM32F4 board I did several steps :1. I created a default NUCLEO413 project,2. I compiled it using the default generated Makefile3. I created a CMake...
Hi! I want to connect to old hoverboard but I can't make connection to mcu. I don't have idea why. I try a lot things but nothing worked. The chip is stm32f103rct6. 10:20:01 : UR connection mode is defined with the HWrst reset mode10:20:01 : ST-LINK...
HiWhen I was returning from RDP level 1 to 0 the stm32cube programmer program crashed and now every time I try to access the microcontroller several different cases happen:1- Connect and instantly lose the connection giving the next error: Error: Dat...
I am planning to develop fingerprint device based on STM32H7R3V8 or similar. It will have 1:1, and 1:N finger matching, and communicate over LAN, WiFi.Will the above MCU be sufficient for a 25,000 users (i.e. 50,000 fingerprints) capacity device and ...
I am trying to enter USART1 bootloader (Pin PC4 and PC5) for STM32G474RCT6 MCUWe are following AN2606 and tried to keep the option bit configurations as per the highlighted row under pattern 14Bit status:The Boot0 pin (PB8) is NOT pulled down with r...
Hello! I am currently working on a project involving a NUCLEO-F746ZG board that is connected to a local NTP server and another board (let's call it X). My board needs to be synchronized with the NTP server and receive 3 pairs of timestamps from board...
I am trying to implement usart2 tx with dma1 stream 6 channel 4. I have tested the usart2 tx independently and it worked perfectly, but the dma part was not that lucky, it just wasn't send anything and I couldn't find anything wrong in my code. Appre...
