Takashi Matsuoka / MjLineSerial

Command line interface for UART.

UARTでコマンドラインインターフェースを実現するためのライブラリです。

UARTからコマンドが入力されるとReadLine関数をコールバックします。

コマンドのデリミタはCR(0x0d)です。

コマンドはバックスペースで消去できます。

#include "mbed.h"
#include "MjLineSerial.h"

using namespace matsujirushi;

RawSerial pc(USBTX, USBRX);
MjLineSerial line(&pc);

void readLineFunc(const char *str)
{
    if (strcmp(str, "apple") == 0)
    {
        line.puts("RINGO");
    }
    else if (strcmp(str, "orange") == 0)
    {
        line.puts("MIKAN");
    }
    else
    {
        line.puts("unknown.");
    }
    line.puts("\r\n");
    
    line.putc('>');
}

int main()
{
    pc.baud(115200);
    line.attachReadLine(readLineFunc);
    
    line.putc('>');
    for (;;)
    {
        line.task();
    }
