Good morning,I am trying to use the RTC and I managed to make it work as expected for the 24hs format, it has no delays and when resetting I could see how to make it save the time but I am having a problem with the 12hs AM/PM mode, the set to go fro...
Hello,Using HAL_UART_Receive_DMA() function and expecting an N length message, so have set the buffer length and transfer size to N.The communicating equipment sometimes adds an extra character / or drops a character which is taking my DMA out of syn...
Hi everyone, I'm working on a project using the Nucleo-G474RE board and the Arduino IDE. I'm aiming to utilize advanced peripherals like FDCAN and USB. While the Arduino Core for STM32 provides a simplified interface, I'm facing challenges in directl...
Hello,I am working on a project using the STM32H745 microcontroller with an MT25QL512A external QSPI flash. I am using IAR Embedded Workbench for development and require the following:.board file: Specific to STM32H745 with MT25QL512A.Flash loader fi...
I'm trying to write three functions: to start an ADC conversion, wait for it to complete, and retrieve the results based on the low-level drivers from ST. The issue I'm facing is that I can read the first channel (LL_ADC_CHANNEL_0) with the correct v...
i recently made a custom board using stm32h743VIT6 and i configured lwip and freertos (before this i was using stm32f407vgt6 it is perfectly working and the circuit is same for this MCUs) now when i start the program it keeps having hardfault i tried...
Hi Sir, 2 pins are configured as I2C functionality and doesn't enable I2C interrupt. Openbootloader is referred to the example of STM32G474E-EVAL I want to communicate with the Open Bootloader using the I2C interface, so from the host side, I execute...
Chip: STM32H747I have setup a master timer. sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE; sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_ENABLE;And two slave timers each with sSlaveConfig.SlaveMode = TIM_SLAVEMODE_COMBINED_...
Hey everyone! I'm trying to decrease the clock speed of TIM3 on my STM32L452RET6 (NUCLEO-L452RE) and i've run into issues. I think i figured it out already but I just don't understand why the problem is. My clock tree looks like this in CubeMX:With t...
Can anyone explain to me what is wrong in my code?Microcontroller: STM32C031K6T6I'm trying to make an interface so that the user can change the name of their environment in real time, my idea and what I tried to write is something that holds the prev...
