I'm having trouble reliably sending CAN messages using the HAL functions (STM32CubeIde) in the way I found in some examples. In those, a message is sent by calling HAL_CAN_AddTxMessage(), but for me that causes nothing to be sent unless I manually cl...
I'm requesting the microcontroller to send data to the PC for every 1.1~1.3 ms through BLE using ACI_GATT_UPDATE_CHAR,However, I'm not sure it is fine because the BLE connection event happens every 7.5 ms.What happens microcontroller and PC In this c...
Hello.There is a board with 2 stm32 MCU, one of them is stm32l452. I need to upload a firmware to stm32l452 using system boot. When it starts in system boot mode, second MCU sends 0x7F waiting acknowlenge byte (0x79) but there isn't a responce. After...
Will a voltage divider and a Zener diode pretty much suffice or will galvanic separation be necessary? Does anyone know/have an out-of-the-box solution?Thanks,Mike
We Want to Log Code Coverage Report for STM32H745XI Dual core CM7 and CM4 Controllers .With single Core Single Project the code coverage is not working we are using OZONE IDE and SEGGER PRO . We need help if SINGLE CORE CODE COVERAGE how ot trigger t...
Hi!I'm trying to save values in the FLASH memory, but the values don't are saved. I've implemented erase command in order to preform flash_program command. I'm using a NUCLEO64 - STM32F303RE...if(HAL_FLASH_Unlock() != HAL_OK) { debugPrintln(&hu...
I recently switched from DMA to IT for receiving commands via SPI. Now I'm noticing that commands are being received and processed correctly, but HAL_SPI_RxHalfCpltCallback() is no longer being called. A lot has changed in my program since then, but ...
Hi Team,I am using the stm32h745-dico board. I am trying to trasmitt and receive the data using DMA through the UART1 from the PB6 & PB7 . Is there any specific streams for Rx and Tx for particular UART.when I am working with the UART3 I used strea...
Hello,I'm curious if there is any way how to load correctly linked elf file into the SDRAM of st32h757i-eval board. By correctly linked elf I mean everything is either linked into SDRAM or to some of the SRAMs. E.g. readelf -S of the elf looks:There ...
