I have two STM32 devices and both are identical, send and receive messages in frame formats. They both have UART, DMA, NVIC etc. And I need a good strategy to setup a lossless communication between them. There is too much information online, but very...
On initialisation SystemClock_Config(0 calls the function HAL_RCC_OscConfig() and this generates a timeout on the loop below: /* Set the new HSE configuration ---------------------------------------*/ __HAL_RCC_HSE_CONFIG(RCC_OscInitStruct->HSESt...
Hi all,I have a question regarding the control of the UART interrupt on the STM32F4.First let me describe the application:int main(void) { SystemInit(); //Stream out Data via Uart via DMA HAL_UART_Transmit_DMA(&huart2, (uint8_t *)UARTMessage_out,...
I have problem with duplicating an existing dual-core project in STM32CubeIDE. in single core project it was just sufficient to copy and paste a project to save it with another name. but for dual core project this doesnot work. hoe can we duplicate a...
Good day everybody, I can't get this simple CAN reception with interrupt to work on my STM32F303VC microcontroller. I have probed the TX and RX lines of the receiving side with a logic analyzer and I saw no problem, however I don't get any interrupts...
Hello.With a preset baud rate of 19200, UART in LIN mode works fine, but the baud rate of the master node is not always known, so there is a need for automatic baud rate detection.If the UART is set to automatic baud rate detection, then the data tra...
I would like to communicate with FLASH using OCTSPI on nucleo l4r5zi. I am creating a driver for OCTSPI for communication, but I have a question.I plan to use the regular command mode, INDIRECT_READ and INDIRECT_WRITE.The driver is designed to stor...
Hi, I created a program that should create repetition on an arbitrary waveform through DMA burst feature. I use circular mode and I decide to stop it when the repetition are done. I use the transfer complet interrupt to increment a variable to have t...
I'm using a STM32L4R9 with a W25G128, using non HAL code. The problem I'm seeing is that auto polling isn't stopped on match per logic analyzer. I have this set up to auto poll for write complete, register 0x05 busy bit 1. The match happens, I clear ...
There is gpio interrupts enabled on both cores, but for different pins.Both cores run mbed os 6.15Programs on th both cores are almost the same:void gpioInterruptHandler () { gpio_irq_disable (); someFlag = true; disableCounter++; } voi...
