STM32H753 eval board NOR flash address lines shorted
I'm using STM32H753 eval board and trying to implement memory tests like data, address pins short, memory cell corrupted etc. on this eval baord there is MT28EW128ABA1LPC-0SIT.for testing address pins short detection I've shorted A4 and A5 pins but H...
Unreliable can wth STM32F0 and HAL, perfectly reliable with mbed
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 sending data through BLE for every 1.1~1.3 ms but I'm not sure it is fine.
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...
Resolved! STM32 system boot USART
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...
Detecting ignition on/off through GPIO in a 12V automotive scenario. What is the preferred way to drive the input, protecting it from getting fried by electrical disturbances at a budget?
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

STM32F3 Write in FLASH HAL_FLASH
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...
Resolved! Do I need to use DMA in order to use HAL_SPI_RxHalfCpltCallback()?
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 ...
