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...
Hi all,I created a dual core project for STM32H745 Disco board. I'm using the cubeIDE and I said "yes" to set all peripheral to their default values. I wonder which core (CM4 or/and CM7) is booting and which was not. The reference manual (RM0399) say...
I'm using the STM32G071C8U7 microcontroller for AC-DC converter, and despite calibrating the ADC and obtaining mostly accurate measurements for all sampled channels, there is an inherent noise problem. When shorting one ADC channel to ground, I can't...
Can J1 apply with 24V so 24V motor can be used on J2?
I am trying to implement application with password access and change option. Please suggest a way to store password/user data in flash memory. Are there any APIs or applicaiton note for more information?
Posted on July 11, 2016 at 17:27I'm working with STM32F070xBI need to configure GPIOs PA11 and PA12 to USB D+ and D- alternate function. According to datasheet it is listed as Additional functions (not Alternate) USB_DM and USB_DP. It is not clear h...
Hi, I am using STM32F407VET6 MCU and trying to receive data using LL API LL_USART_ReceiveData8 over USART configured as modbus. I confirmed USART transmit (LL_USART_TransmitData8) is successful through an modbus APP, on rx side of the other devi...
I am using STM32H753ZI for my project. My use case is I want to detect brown out reset after brownout occurs and system restarts.I am checking brownout reset flag using if (__HAL_RCC_GET_FLAG(RCC_FLAG_BORRST). My query is this flag is shared/common b...
Hi,I am using STM32H743II microcontroller. In which communicating with external SRAM with FMC. It is working fine.I need to communicate with the touch LCD IC via I2C. There is no problem in communication when FMC is not active. I am reading the touc...
I need to write firmware for STM32H7xx to interact with an SPI flash memory chip. (STM32 master, 8-bit, full-duplex polling, no CRC and application controlled #CS.) I am using STM32CubeIDE 1.14.0 and used the device configuration tool to produce my S...
Here's how I implemented a custom bootloader using the STM32L475. I thought I would share since I have seen so many posts from people having issues invoking their application from their bootloader.I attempted to post this as an idea in the knowledg...
