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
Hi All, I am trying to reduce the boot up power consumption using STM32U575RIT6xQ . I using a 4-20mA power source and the boot up power is 7.6mA. After it boots up the power consumption is 3.4mA. We are using Free RTOS. Below is the pins that are act...
