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...
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...
