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 ...
Hello everyone, Can anyone check out the power supply scheme I followed is recommended. If deviated please do suggest the right circuit. @stm32
I'm on Nucleo-F303RE board, which according to the page 129-130 of the reference manual (RM0316 Rev 10) I should be able to set "TIMx (x = 1/2/3/4/8/15/16/17/20) can be clocked from the PLL running at 144 MHz when the system clock source is the PLL a...
Hello everyone, I need help .I noticed a very interesting problem, which is this.I use STM32F429I-DISCO1 when I activated I2S_2 in the master mode PORTB_13 pin = CLK , but in reality it was always = HIGH level , after that I deactivated I2S_2 and con...
