I am using the STM32H743ZIT6 MCU to enable USB CDC. In my schematic, I have not defined the VBUS pin; I have only defined the CDC lines. Can I still use CDC without the VBUS pin? Below is the photo of my schematic for reference. Please help me.Thank ...
Hello,I would like to know if it's possible to configure my evaluation board HSI, I have this code and I would like to adapt it on my evaluation card and see if it is compatible with the rest : // HSI // void SystemClock_Config(void) { RCC_...
Hi STM32 enthusiasts, I’m reaching out to the community for advice and guidance on an issue we’re facing while developing an external loader for our custom board. We’ve been working with the STM32H730IBK6Q chip and an external memory MX25LM51245GXDI0...
Given: void USART2_Init (void) { RCC->APB1ENR |= (1<<17); RCC->AHB1ENR |= (1<<0); GPIOA-> AFR[0] = (7<<8); GPIOA->MODER |= (1<<5); USART2->BRR = 0x0683; // 9600 at 16MHz USART2->CR1 |= (1<<3); USART2->CR1 |= (1<<13); } void USART2_Write(...
Hi everybody,I have TIM15, configured to PWM generation, in one shot configuration, using OC1N output. The output is set to 0 and timer disabled.. When I later initialize TIM1, the output of TIM15 goes high at the instant the Update event is generate...
Background: We have a board that uses Quad SPI on STM32H750 to interface with Macronix MX25L12833F Flash. We are using the flash to support a large firmware image (with XIP). We are attempting to take this hardware and drop in STM32H733. Doing this...
Hello all, My aim is to utilize the User Push button (configured as an EXTI gpio) on Nucelo-F411RE board along with a software reset to enter the System Bootloader located @0x1FFF0000 (ref: AN2606). With the software reset implementation, I face the...
I am using STM32H753.My TIM2 is in Encoder mode, and I give two external signals from my incremental encoder to TIM2_CH1 and TIM2_CH2. My TIM2 is counts perfectly (Up or Down) when I move the encoder clockwise or anticlockwise.Now i want to syncroniz...
Hello,I am attempting to make an external loader for a QuadSPI flash S25FL256SAGMFI000 using the STM32F769 and STM32CubeIDE.I followed this tutorial: https://www.youtube.com/playlist?list=PLnMKNibPkDnHIrq5BICcFhLsmJFI_ytvEI was able to run the code t...
Hello,I have a board with a STM32U575RGTX CPU, and i use SPI1 with a 2.8" TFT ILI9341 Display.I got problems with the GPDMA1 configuration, and need help.main.c: int main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configur...
