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...
Hello together,even this is freeRTOS related, i hope this is the correct place for my problem.I have the following Board with an STM32F407VET:I started from a github repo with a working configuration:https://github.com/art103/JZ-F407VET6I removed eve...
Hello,I'm contacting you regarding a support request concerning the wakeup from shutdown mode of the STM32C031C6T6: The issue we're facing is that __HAL_PWR_GET_FLAG(PWR_FLAG_WUF2) returns True when I power up my STM32, even though I haven't triggere...
