Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hello,When I try to read USART status register (RXNE bit), the execution stucks upon while loop which means no data have been readen: char uart2_read(void) { while(!(USART2->ISR & USART_ISR_RXNE)){} return USART2->RDR; } I think I initialized eve...
Hi there,I am seeking some guidance regarding the connection of the STUSB1602 to the STM32L031G6U6 microcontroller for a low-power application with a small footprint.Currently, I have already connected the STUSB1602 to the microcontroller using the I...
Hello, I'm trying to determine the source of the wakeup flag, whether it's the power being turned on or the trigger of wakeup pin 2.So this is my shutdown function:After i changed my shutdown function : when I try to determine the reason for the w...
Hello ST Community,I am currently working on a project using the Nucleo-H753ZI without an RTOS, and I have followed a tutorial by Controllers Tech to set up TCP/Ethernet. I am using Static IP assignment.I can Transmit and Receive data though Hercules...
Hi,I would like to create a gamepad that is recognized by the computer (windows), and have the Virtual Com Port (CDC) to send en receive data with the computer. For that, I want to create an USB Composite with HID+CDC. I found an exemple on this webs...
i use stm32f407vgt chip with my own board designand working on STM32CubeIDE_1.3.0 void USART3_IRQHandler(void) { /* USER CODE BEGIN USART3_IRQn 0 */ //USART3->SR &= ~USART_SR_RXNE; LL_USART_ClearFlag_RXNE(USART3); static unsigned char iterat...
Hello,I have created my own board in zephyr (using STM32U575).Now I would like to configure the power mode pins (CSLEEP, CDSTOP, SRDSTOP ) in the devicetree of the board.I have therefore implemented the configuration for the pins in the .dts file: &p...
hello,expertorI wanted save lillte data about 2K,to stm32F407_ve internal flash.but,i study demo about FLASH_EraseFlash,it only have erased sectores.F407 ve have 4(16K) sectores,1(64K) sector and 3(128K) sectores.its waste for only 2K data.have other...
Hello everyone,Now I am trying to test the Ethernet on our custom board with STM32F765 and MAX24287 via MII mode. Firstly I configure to test the transmit receive raw data with diagnostic loopback mode. From oscilloscope I saw the the data output fro...
Hello, ST expert STM32F407 is used for our custom design. And htim2 play the role of precise timing base.When htim2->Instance.CNT = xx is used for setting a new counter start value for timer2, it seems that the new counter value does not functions i...
