stm32 cubemx i2c 中断模式 stm32f4中断 概述 异常是导致程序流更改的事件,当一个异常发生,处理器会挂起当前正在执行的任务,并跳转执行响应的异常处理函数。在执行完异常处理函数后,处理器会恢复刚刚正常的程序执行流程。在ARM架构下,中断是异常的一部分,中断通常由外设或外部I/O引脚产生,在某些情况下,它们...

测试方法:用一个USB转I2C的工具接到STM32的I2C引脚上,通过上位机工具进行读写操作。如果没有这个工具,也可以用另外一个stm32或者其他设备测试通讯,同时也可以借助示波器或者逻辑分析仪来辅助调试。 硬件连接: STM32这边使用硬件I2C1(PB6、PB7),并外接上拉电阻。

In addition to reading and trying to understand RM0033, I also tried looking for an example interrupt handler, to see if anything was being done differently. It's the stm32f2xx_it.c file in I2C\I2C_TwoBoards\MasterReceiverInterrupt in the standard peripheral library (the author...
