If I comment out lv_task_handler and, of course, my OLED display can not display but uart rx interrupt callback start to work. (Note:When uart rx interrupt callback work , uart rx will echo back the received char to uart tx. When uart rx interrupt callback can not work , uart rx ...

C语言程序开发中关于函数返回值的问题 C语言函数可以通过返回值表示输出结果,例如 log() 函数的返回值会根据不同的输入,返回不同的值。再比如,我们定义一个函数 myopen(),用于打开某个文件,那么,这个函数要么能够成功打开文件,要么打开文件失败,这时,可以通过返回值区分“成功”和“失败”。 2022-09-06 10:01...
That’s means that the interrupt handler function is executed in SRAM1. 13. Select Run -> Remove all Breakpoints and stop the debug session.Conclusion: This example is equivalent to the previous chapter. It can be used to place and execute a single or several interrupts’ handlers ...
打开code\1.basic\UART_Txpoll_RXinterrupt\Project\wolf32f031_UART .uvproj,编译并下载工程。 3.3下载完成后,确认连接好串口,打开DNW,选择好相应串口,设置波特率为115200,给评估板上电,观察DNW接收数据,点击键盘上任意字符键,观察DNW接收数据。
