Hi I have a a stm32L433 48 pin processor and trying to get it into low power. I am using the STLink-V3PWR module with stm32Cube Monitor Power module. First of all I placed a known value resistor across the STLink-V3PWR to make sure it is reading ...
Posted on March 21, 2016 at 17:25We have a batch of boards in the field where the LSE crystal may be marginal and I'm wondering if there's a way to check for the LSE losing lock after initially being locked. That is, if on initial clock setup I get...
Hi all,i have selected the MCU STM32C051G8GU6 as the main controller of the RFID system and i am trying to use the MCU without using any external crystals or oscillators, can anyone please guide me how to use the internal oscillators.Thanks in advanc...
HelloI am creating a program using STM32C031.Before entering while(1) when powering up, I would like to use HAL_I2C to retrieve EEPROM data from the IC, and then start the USART1 and USART2 receive interrupts and the SPI1 transmit interrupt.However, ...
Took me a little while to work this one out so though i'd share.My goal was to use the RTC wake up interrupt as the time source to periodically flash a LED. STM32CubeMx Configuration:To configure the RTC, I used the code from the cube L0 firmware ex...
I would like to know the necessary operations and settings from power on to GPIO control.I have made a board using STM32H743XGH6.I want to set the GPIOs to turn on the LEDs, but it does not work.I am setting the GPIOs by manipulating the registers di...
I am studying the architecture of the STM32H7 family, and according to the AN there are various types of memory, DRAM, SDRAM, NOR/PSRAM, NAND in addition to the swap between SDRAM and NOR/PSRAM.What is the reason for such diversity and what benefits...
Greeting Everyone,I am facing an issue with my STM32 board having STM32F103C8T6 as MCU, while trying to see a normal "Hello World" output. After debugging the board, I attempted to connect it to my PC via the serial port. To ensure proper communicati...
I was wondering by which reason the HAL_LPTIM_AutoReloadMatchCallback is not being called. All the functions called in the inside the HAL_LPTIM_Init return HAL_OK.
Hi,I've been searching for STM32U5G9ZJT6Q BSDL file, but I couldn't find it. Could anyone please share it with me?Thank you,Best regards
