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.
In the ADC scan mode in STM32 microcontrollers, the digitized value of all input channels is dumped into ADCx->DR. Is there a register or flags to find out which ADC channel the data currently in the ADCx->DR register```void HAL_ADC_ConvCpltCallback(...
Trying to connect to a STM32H723ZGT6 for the first time. Does the ST/LINK-V/2 have to use the JTAG connection on this device as I feel it probably does? The 4 pin connection being for the STM8 only? I jave connected as a JTAG connection using jumper ...
