Resolved! Core comunication using STM32H7
Hello, What is the best way to communicate between cores? I am working on a project in which I need to read data using one core and process this data using a second core. I am working with a STM32H745. The idea is that the M4 core is going to be used...
Replace RTC Crystal with RTC Oscillator ?
We are working on a custom board based on STM32L476RGT6, and we are facing 32.768Khz crystal startup issue. Board stucks at the startup in following piece of code : HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) and it fails while waiting for RCC_L...
Having problem with UART communication in Interrupt mode
I am doing a project on STM32H747 DISCO Discovery board involving UART. I am sending one string continuoulsy with 5 seconds delay from esp32 to stm32. I am able to receive the string in polling mode but I am not able to receive the string in Interrup...
Resolved! I have create a project to communicate via a fdcan bus on stm 32h723zgt microcontroller but i have no interrupt generated
i have connected the tx pin to rx pin on fbcan3 interfaceyou will find my project in attacheementthanks
Weird PWM Timer3 master and PWM Timer1 slave behaviour
Hello, I have a timer 3 master and timer 1 slave. When a button is pressed, master is activated as long as button is pressed, and then slave is triggered based on master's output signal (high / low) (gated slave control)(This is a continuation of my...
STM32F746GDISCOVERY, PWR_PVD, STM32CubeIDE
I want to make an interrupt when power > 2.0V. STM32CubeIDE generated:/** * @brief NVIC Configuration. * @retval None */ static void MX_NVIC_Init(void) { /* PVD_IRQn interrupt configuration */ HAL_NVIC_SetPriority(PVD_IRQn, 8, 0); HAL_NVI...
Hello I'm useing UART with a CTS line for hardware flow control. Is there any way to configure an interrupt for the same pin where the CTS line is connected? Can i call any callback function that i didn't find?
I'm working on a STM32MP1xx board and I'm useing only the Cortex-M4 for this UART configuration.
Resolved! RTC inaccuracy induced by internal clock source?
I'm using the STM32L431xx mcu. The current hardware configuration of our design has no external clock source (crystal), so we are using the internal one. And there's a new functionality which demands second-accurate real time clock, over a period of...
I2C in DMA mode - deadlock on I2C interrupt
Has anyone have similiar issues ? I got I2C DMA writes working nicely on table, but in real application there are disturbances which cause false start condition on the bus.This happen when I2C HAL driver has "lock" on I2C handle - so incoming interr...
