Incompatibility in CAN implementation between HAL and SPL due to possible bug in HAL

HiWe are trying to communicate between an F407 Discovery using SPL's CAN implementation and F756 Nucleo running HAL's CAN implementation.Here is the calculation for time quanta and Baud rate...Baudrate = 1 / Nominal Bit TimeNominal Bit Time = 1 x Tq...

For interrupt priorities set using the STM32IDE CubeMX, where are the auto-code generated HAL_NVIC_SetPriority() calls located?

I could locate the HAL_NVIC_SetPriority() calls for DMA and EXT1 Interrupts in main.c as shown below.I could not find the  HAL_NVIC_SetPriority() calls for RTC, USART & Timers - TIM4, TIM5, TIM6, TIM7. Where is the interrupt priority for these periph...

stm32f4 family gpio boundary address

helloi'm having a question. why gpioX boundary address(range) is 1kb ???according to datasheet, GPIOA's boundary address is 0x4002 0000 - 0x4002 03FF.but offset for register to be set is 0x00 - 0x24. i think that using 1kb to cover that range is inef...

STM32F103 built-in bootloader does not respond: how to debug?

I have STM32F103T6Ux. I'm trying to communicate with the built-in bootloader, so we can do software update via UART. I'm setting BOOT0 pin high and it seems the system is in bootloader, since our normal code doesn't come up. I'm setting my side of UA...

Getting Error "undefined debug reason 8 - target needs reset", BluePill, ST-Link V2, & STM32CubeIDE, STM32CubeProgrammer is able to download the code to the BluePill & run,while I have no debugging problem at all when replacing BluePill with H743 board.

Use HAL_I2C_Master_Receive_DMA when the receive size is contained in the first received byte?

I'm working with the Nucleo-64 development board with an STM32L476 microcontroller. I wish to receive data over I2C using DMA with the function HAL_I2C_Master_Receive_DMA. However, to use that function I need to specify the parameter Size, and I don'...

Why does the STM32 not start as stand alone, but it starts connected with STM32CubeIDE?

Hi,we work with Nucleo STM32G031K8 board and STM32CubeIDE. The example program Blinky (its full name is GPIO_InfiniteLedToggling_Init) is working as expected. The LED is toggling also with extern power supply instaed of USB power.Now we have programm...

HAL_UART_Transmit sends extra '00' between each byte

This is probably a simple question but I can't find a reason for it - Im using the USART on a stm32L412 and I am sending 3 bytesuint16_t SendDataOn[3]={0x90,0x3C,0x3E}; HAL_UART_Transmit(&huart1,(uint8_t*)SendDataOn,3, 100)Except when I send this, I ...
