在这个应用程序中，Label组件可以用于添加提示语句，Entry组件可以接受用户输入的串口号、波特率等参数，Button组件在设计时应该能够实现连接和断开操作等。在代码中，需要使用pySerial模块实现串口通信，来连接STM32和ESP8266模块。首先，需要导入pySerial模块，并通过串口的设定创建Serial对象，设置好相关参数，然后使用open()...

Linux内核使用结构体softirq_action表示软中断, softirq_action结构体定义在文件include/linux/interrupt.h中,内容如下: 示例代码31.1.2.1 softirq_action结构体 541 struct softirq_action 542 { 543 void (*action)(struct softirq_action *); 544 }; 在kernel/softirq.c文件中一共定义了10个软中断,如下所示:...

执行WFI (Wait For Interrupt) 指令或WFE (Wait for Event)指令。进入Sleep Mode的机制可以通过Cortex-M0 System Control register的SLEEPONEXIT bit来选择: Sleep-now:SLEEPONEXIT bit置零,在WFI/WFE指令执行之后立即进Sleep Mode; Sleep-on-exit:SLEEPONEXIT bit置1,在MCU退出了最低优先级的ISR之后,即系统没...
