UART(通用异步收发传输器)Over-run中断指的是在UART接收数据过程中,由于数据接收缓冲区已满,而新的数据仍然不断到达,导致旧数据被新数据覆盖的现象。此时,UART会触发Over-run中断,以通知处理器有数据丢失的情况。 UART Over-run中断发生的可能原因 波特率不匹配:如果发送方和接收方的波特率不一致,可能会导致接收方无...

4、当发送 PHY 为 1M 时,如此发送透传数据不会出现任何问题,当 PHY 设置为 2M 时,串口会出现 Uart Error over run 错误,我已经将 uint8_t uartCC26XXRingBuffer[CC2640R2_LAUNCHXL_UARTCOUNT][600];,查看了串口缓存也是没有满的,但是会莫名出现 Uart Error over run ...
I can pause my debugger and see that there is an interrupt pending, but the code never jump into the ISR to service the interrupt. If a bit is set in the CPU's IFR register, and that same bit is set in the CPU's IER register, and if the GIE global enable is set, then...
0 @Marc Crandall over 12 years ago Hello, Using tasks should not change things too much. Often events are used to signal to a task that an interrupt has occurred. For example: TASK - __task void task_uart(void) { for (;;) { os_evt_wait_or(CHAR_READY_EVENT, 0xFFFF); // ...
s first recourse may be to use delays to properly time the output data stream. This has the drawback of wasting processor cycles and doesn’t let the microcontroller do much else useful. Instead, [Marcel] discusses the proper way to do things, through the use of interrupt service routines ...
Also, for UART, the Hardware Interrupt Callback block can be added fromISR Blocks: Here, the previously configured Interrupt handler (MBDT_Uart_Callback, see chapter 2) must be selected: TheHardware Interrupt Handler Blockis used to display all the user defined callbacks th...
我在Aurix Development Studio 中遇到了一个问题,其中包含的某些函数(AppInit()、 blinkLED()、 NvmInit())会阻止 runShellInterface() 的执行。但是,注释掉这些函数 后,runShellInterface() 可以 正常执行。 受影响的功能:AppInit(), blinkLED(), NvmInit(). 预期行为:执行这些函数后,runShellInterface() 将...
