PIC18F 串口环形缓冲区测试，通过电脑串口调式助手向设备端发送指令字符串，设备端识别指令后，返加应答指令字符串。所有的事件由电脑端发起，设备只能响应请求！-PIC18F serial ring buffer tests through the computer serial port tuning assistant sends command strings to the device, device-side identification instruction, returning r

建立环形缓冲区，将发送缓冲区建立成一个环形的缓冲区，在这个环形缓冲区内，通过头指针和尾指针来定位空白区和数据区-Ring buffer and send buffer created as a circular buffer in the ring buffer head and tail pointers to locate the blank area and data area

基于Z85C30实现USB转双通道同异步串口的源码，本程序采用环形缓冲，多中断等方法实现了串口数据和USB数据的交换，由于单片机速度限制异步只能做到100K，同步只能做到57k。-Z85C30 based USB to dual channel asynchronous serial source code, the program uses a ring buffer, multiple interrupt other methods to achieve the serial data an
