Posted on November 10, 2014 at 14:30Hello. I am using the new HAL library for writing a program for STM32F4Discovery (for university presentation). The program activates a USB FS CDC device once running to speak with a PC. I've attached an SD card s...
Hi, I'm trying to use FreeRTOS Tickless idle mode. When I am debugging my code (using breakpoints), I see that the code enters vPortSuppressTicksAndSleep function. /* Sleep until something happens. configPRE_SLEEP_PROCESSING() can set its parameter ...
We are building a test card for a host that embeds the STM32L552 microcontroller in it. The data lines are broken out and VDDUSB is tied to the same voltage as the VDD for the MCU. Do we need to use VBUS in this case? Please advise.
Hi! I'm really new to this, so sorry if this is a dumb question, but I'm currently trying to make my STM32nucleo-F103RB work as a keyboard, i've followed a few tutorials but I have a problem when connecting my MCU because when I connect it to my lapt...
I'm stuck on performing jump to bootloader in order to update firmware via DFU. MCU is STM32G484. On empty project I configured the clock for USB, my code is: int main(void) { HAL_Init(); SystemClock_Config(); /* Initialize all configured peri...
The STM32F767.svd file is provided by the STM32CudeIDE, within the com.st.stm32cube.ide.mcu.productdb.debug_1.5.0.202011051456 directory. The two forgotten definitions are :field CAN3EN in the RCC_APB1ENR register;field CAN3RST in the RCC_APB1RSTR re...
For a specific application, I’d like to decrease the main clock (MSI in this case) in runtime. Frequency scaling itself is not an issue but after scaling, Threadx timings are not correct anymore (since TX_TIMER_TICKS_PER_SECOND is not correct anymore...
Hello, I am designing board with stm32f723 with 2 USB. On one side i have mouse attached to STM on other side STM attached to PC. When i transfer report to PC x, y and left click button works fine but i cant make right click. Bellow is the struct of...
Hello everyone,I am facing an isssue related to Bootloader project in STM32F407VGT6. My bootloader placed at start address of internal flash memory 0x0800 0000 and occupied 16kB. My application's size is 74kB. If the application is placed at 0x0806 0...
