Hi Everyone, I am trying to interface with LCD16x2 on STM32F030C8 custom board but I have some issues. I have LSE crystal on my custom board but HSE is not. When I debug my code, I have this problem: And when I run it, program does not work well and ...
Hi community ,I'm currently working on STM32H747I DISCO0 Board .The peripheral I'm using is QSPI, I'm able to read/write and also enter Xip mode in CM7 .Problem:1)QSPI does not work in CM4 .Need to access QSPI in CM4 and perform same operations as re...
Hello, I'm building a project where I will use CAN, UART and a TIMER. All of these work with an interrupt. How it works: I get data via CAN and use a TIMER to send a Request on the CANbus. With the UART I need to receive some commands that will trigg...
Hi, STM32H743 development kit to develop my board.I want to develop my board in a way that each hardware interface can be selected between AI, AO, DI, DO by software. Is there any reference boards or reference documentations to implement such applica...
hello,Im trying to send the data I received on USB port (succesfully) to the UART port i tried sending data between 2 windows in Hercule, one is connected to the USB port, the other is connected to the UART port with the right configurations. I provi...
Hello.I'm using STM32F407, use usart3 set DMA setting baud rate 9600 and use receive void HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t Size){if (huart->Instance == USART3) {HAL_UARTEx_ReceiveToIdle_DMA(&huart3, RxBuff, Size);__HAL_D...
Helloscenario: I have a Nucleo WB55 board with embedded ST-Link, and I'm able to program the mounted SMT32 with Cube programmer. I have used since few days ago the embedded ST-Link to program custom HWs, removing the jumpers on NRST, SWO, SWCLK, SWDI...
i've recently purchased STM32H735G DK board. When i connect it to PC via USB cable, it screen is showing output as per already programmed code and its working.power LED (LD5) is green and STlink LED (LD6) is red.But when ever i try to load a new code...
Hi there, should anyone recommend an I2C module for communicating with STWLC-GUI ??I have one already, but I need one more.Thanks.
Does anyone know the exact pin-out of these five pins? I cant find anything in the documentation. Hoping it will allow me to use an external programmer.
