My STM32H743 SPI interrupt handler is being repeatedly called even though the interrupt enable register (IER) is 0. I'm running in slave mode and probably doing something really wrong for this to happen. Here are the register values:Name Value Ac...
Hello,I am utilizing the FDCAN1 CANbus protocol on the STM32H725AGI6 MCU currently. I am trying to determine the execution time for the firmware to execute the lines of code, as the timing can be critical in some applications. So for example, I woul...
Hi all, I was wondering if there is a way to set up the LSE as the source for a Timer on the STM32F030R8 to generate a PWM output signal. Currently doing a deep dive on clock configurations, timers, etc. and I have been able to use the HSE for PWM, b...
Hi i m using 26 keyboard key to interrupt via UART received, should i coded the 26 interrupt in a single rxcplt callback function or a multiple callback function? Whats the best way? pls advise...void HAL_UART_RxCpltCallback(UART....){ HAL_UART_Rece...
Hi,I'm having problems with STM32H723VET6 (100 pin device) and ULPI using USB3343. After ULPI reset USB3343 starts the USB clock (60MHz). But when I enable MCU ULPI clock with __HAL_RCC_USB1_OTG_HS_ULPI_CLK_ENABLE() the USB clock is stopped and never...
Hi,someone knows where the Backup SRAM is located on STM32H563 (at which address)? I didn't find it in the documentation.Thanks
Hello,All of the interrupt handling routines in startup_stm32f765xx.s are marked as WEAK linker references. However it appears that some routines can not be overwritten. SysTick_Handler (sorry) is one of those. There are many solutions posted in the ...
Hello,We have a custom board design using STM32F765IITx processor. Trying to configure and generate a working project using the HS USB interface with an external PHY. (USB3315) The project being generated is for Keil (MDK-ARM)The latest versions of S...
Hello,I am new in the STM world.I am using the nucleo-H563ZI deverlopment board and I want to get the virtual COM port to work.On github I found the examples of the Board.https://github.com/STMicroelectronics/STM32CubeH5 I opend the project "...\Proj...
I'm working on a board with a STM32L010K.For some reason, I can't get the I2C code to work properly. I mean it works (data gets read from the slave) but not if a lot of things are done in succession, then a hard fault is thrown.Below is the block rea...
