void Timer0_isr(void) interrupt 1 基本格式,其中interrupt为优先级,定时器0的优先级为1,而外部中断0为0,外部中断1为2,定时器1为3。 当开启定时器即TR0/1=1;此时进入定时状态,而这时主函数还是一样在运行,定时器在定时,直到定时到我们设定的定时时间时,主函数暂停运行,进入到中断函数,执行中断函数,执行完...

Interrupt Subroutine. The ESP8266 has two different kinds of interrupts: “external”, and “pin change”. ESP8266 all pins have external interrupt except GPIO 16. These interrupts can be set to trigger on RISING or FALLING signal edges, or CHANGE of level. ...
//already move uart buffer output to uart empty interrupt //tx_start_uart_buffer(UART0); #else #endif } } 在这个里面就是把接收到的数据通过 uart_tx_one_char(UART0, d_tmp);一个个的发送出来,如果我们想处理 自己接收的数据,只要把它放到缓冲区就处理就可以。
函数： digitalPinToInterrupt(pin) 参数： pin：要获取中断号的GPIO引脚。例⼦ 将NodeMcu的D2引脚设置为上升沿中断。在D2上外接⼀个按键，按键通过电阻下拉到地。当发⽣中断的时候，我们在串⼝监视器上打印“Hello ESP8266”。/*...
