I am using the Nucleo-H743ZI, with a SPI ISR I wrote originally on the STM32H7B3I-DK board. However, when I usevolatile uint8_t rxBuffer; volatile uint8_t txBuffer; *((__IO uint8_t *)&hspi->Instance->TXDR) = txBuffer; //or rxBuffer = *((__IO uint8...
I've got an STM32H7RS, and am attempting to use HPDMA to do a memory-to-memory transfer where one side is the FMC.The transfer works perfectly if I use GPDMA.With the exact same code (just replacing the GPDMA handle with an HPDMA one) does not work (...
Hello,I'm using the STM32F767ZITx MCU and the lwIP library to transmit and receive UDP packets every 1 ms.Everything works fine but sometimes, after the ARP table has expired, UDP packets are no longer transmitted for several seconds even though my S...
Hello, I'm trying to do a quick test with the STM32F412G-Discovery kit and the analogue microphone input.I use this example https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Projects/STM32F412G-Discovery/Examples/BSPwith the menu #### AUD...
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...
