If the H7 HAL_SPI driver function HAL_SPI_TransmitReceive(......) is called in my main(),It runs correctly, I can transmit and receive data correctly. But it is called in my EXTI9_5_IRQHandler() interrupt , It runs dead loop, and can't return.
hi dear.I have some problems with the Flash bank configure.STM32F767 is used by setting Flash Bank to Single or Dual.So I want to set Dual Bank Mode on Flash Memory.However, the Dual Bank setting does not work properly. I changed the Option byt...
Hello all,I have STM32F439 MCU.I use STM32CubeProgrammer to program the MCU through ST Bootloader.STM32CubeProgrammer writes:Bootloader protocol version: 3.1According to AN2606 (STM32 microcontroller system memory boot mode) the valid version for ST...
HiI'm using a Nucleo-144 with a STM32F767ZI.I have included in my project FreeRTOS and FreeRTOS-IP although that may not be related with the problem, since the crash happens before reaching the initialisation of FreeRTOS.My problem seems to be that H...
Ok, I scratched my head long enough and now my hope lies with the ST Community. =) I would like to understand how this code in the header file stm32f1xx_ll_gpio.h works. In particular, what does (Pin >> 24) do? I suspect that the code sets two regist...
Hello , I had started a project with STM32F410RB wish communicate with a keyboard and LCDActually i wrote my program that call SysTick_Handler from stm32f4xx_it.c to interact keyboard and detect if there is a button pressed and wrote caracter on LCD....
can we achive USB 2.0 on STM32L152RCT64SF without oscillator?
Hi I want to measure the CPU usage of the tasks running by FreeRTOS.I use the following code, but I see very inaccurate results.I want to use a sliding window, or even a timer.Is there a known solution or good practice to do so?I use FreeRTOS with ST...
Hello comrades. I am using CubeMX to implement USB MSC host and FatFs on STM32F767. My task is to periodically write files to various flash drives. When I first insert a USB drive into my device, everything goes right: in the APPLICATION_READY state,...
The HAL SD Card initialization routines queries the uSD Card for various pieces of informationin the initialization routine. If a uSD card not present, the initialization fails. Further, this means that it is not possible to remove and replace the...
