I have a question regarding uart_interrupt.c: How does the ISR (DEMO_UART_IRQHandler) get invoked? I cxhanged the example code from using UART0 to using UART4 and have updated the macros like this: #define DEMO_UART_IRQn UART4_RX_TX_IRQn #define DEMO_UART_IRQHandler UART4_R...
163 UART_Init(TEST_UART); /* 使能UART */ 164 165 UART_GetConfig(TEST_UART, &UARTConfigStruct); /* 将参数赋值给UARTConfigStruct */ 166 UARTConfigStruct.baudrate = UART_BPS; /* 设置波特率 */ 167 UARTConfigStruct.databits = UART_CFG_DATABIT_8; /* 设置为8位数据 */ 168 UARTConfigSt...
Hi I want to open uart interrupt.I set the following register, or I can't access it(void UART1_IRQHandler(void)) please can you help set the
In this tutorial, we will show you how to use STM32 Blue Pill UART in interrupt mode to transmit and receive data. We will use STM32 CubeIDE to create a project where we will use UART interrupt of STM32 Blue Pill to receive data on the Rx pin via interrupt and we will send serial...
I am trying to write a simple interrupt service routine for UART. MY code is as follows: in main function: alt_ic_isr_register(UART_0_IRQ_INTERRUPT_CONTROLLER_ID, UART_0_IRQ, &receive_data, uart_capture_ptr, 0x0); ISR function static void receive_data(void* context) { // ...
UART(通用异步收发传输器)帧错误中断是指在UART通信过程中,由于接收到的数据帧不符合预期的格式或规范,从而触发的一个中断信号。这个中断通常表明UART接收到了错误的数据帧,需要进行相应的错误处理。 2. 可能导致UART帧错误中断的原因 数据位不匹配:发送和接收端配置的数据位长度不一致。 停止位不匹配:发送和接收端...
