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...
Resolved! How can I use UART manually, without HAL_UART_***() functions?
NUCLEO-H723ZG dev. kit.I need take over the full control of the USARTx. I need a TX interrupt and the RX interrupt handled manually independently the HAL_UART_*** functions. The HAL_UART_Receive_IT() and the HAL_UART_Transmit_IT() is useless for me. ...
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...
