The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I'm unable to successfully see my PWM signal on the Nucleo STM32F302R8 development board, connector 10, pin 37.I have SB62 and SB59 connected with 0-ohm resistors. I don't understand why the same pin is on multiple pins. Absolute pin number 17 AND ...
Hi,I am new to microcontrollers and this is my first big project. I want to receive data from other device through 8 data lines and 1 clock signal (similar to STM Application note AN4666 ''Parallel synchronous transmition using GPIO and DMA'')I am us...
When trying to initialize external SRAM in the SystemInit() function in system_stm32lf76xx.c, I call HAL_Init which calls HAL_InitTick. This function calls HAL_SYSTICK_Config which uses the global variable SystemCoreClock to initialize the SysTick. H...
Hello,I have recently moved RAM from DTCM to AXI SRAM (so that I get more RAM).It then failed in dma example.After investigation I found out that the call to SCB_InvalidateDCache results in HardFault_Handler.I've changed it to use SCB_Invalida...
Posted on February 19, 2015 at 10:57Hi all,Is it necesary to implement a additional code in my application to jump to the bootloader? #magic-eight-ball
In my STM32L432 project (Keil) I need to use a system reset.System should be able to reset by external command, and it's also used in bootloader<->application jumps. I am using HAL_NVIC_SystemReset() for this purpose. I've noticed that once in a whil...
Hello everyone,I want to do not change date, When I load a new program to STM32F103. How can I do these ? Thank you
Hey guys,I have expereinced a very strange behaviour of my STM32F429ZIT6 custom board:When I execute the following code the processor behaves differently in free running then in manual stepped mode or my oscilloscope seems to be completely broken - w...
HelloI would like to know if all STM32 cards have dual bank flash mode.I have two cards, a STM32F746 Discovery and a STM32L475 Discovery. Apparently the STM32L475 has mode but not the STM32F746.Is that right?If a card does not have a mode, is there a...
