Supposed I am using external memory via an 16 bit address / 8 bit data bus with FSMC (STM32F714). An RTOS is running.Is access to this memory atomic (in the sense of thread safety) when I read/write 32 bit wide data? The consideration is, for instanc...
Hi all,Bootloader selection for STM32G47xxxx described in AN2606 shows the different steps followed by the bootloader.Where can I find the delays available between steps ?For example, how long the booloader waits to receive the 0x7F value on USARTx ?...
Hello, I am trying to start the bootloader on a STM32F427 to program the MCU via USB port in DFU mode. I am not new to this topic because I wrote some programs for STM32F072 where I can successfully start the bootloader and take externally control of...
I'm planning to use a cheap STM32 board (either with a F103 or F401/11) as a joystick/rotary encoder controller for arcade games. I already have a working proof of concept using the old STM32duino cores (not HAL based), but I prefer to use the HAL en...
Welcome everyoneI used Free ROS with two tasks, the first task was to blink the led and the second task was to receive from uart and then to resend the received message. The two tasks have the same priorityThe led flash works fine but the uart only r...
I didn't find a good tutorial or a legit example code to initialize the ethernet protocol. My project use UART communication at the moment but I need the ethernet. Is there anybody who could help me?Thanks a lot!
Hello!When trying to implement USB OTG HS Host, I am running into an issue. In file "stm32f4xx_ll_usb.c", function "USB_HC_StartXfer" there is a piece of code that enables the USB_OTG_GINTMSK_PTXFEM interrupt. However, it then proceeds to write the e...
hello everyoneI'm working on a USB MSC application. Standalone works fine. When I create code with FreeRtos, the hal_delay () functions are left in the usbh_conf.c file. Replacing the hal_delay codes generated by cubemx with the following codes, ther...
Hi,these defines are defined very strange/misleading in STM32H743xx.h (from current version 1.7: STM32Cube_FW_H7_V1.7):#define LPTIM_CR_SNGSTRT_Msk (0x40001UL << LPTIM_CR_SNGSTRT_Pos) /*!< 0x00080002 */According to RefMan Desc of SNGSTR...
I can get my USB CDC on Nucleo-144 recognized from Device Manager. It will appear like COM8 and Terminal Emulator can connect to it. I can even echo back data received.Just when I add some minor functionality in the while loop in main() (like check f...
