Daisen Remote library

DAISEN リモコン用ライブラリ

Sample

リモコンの受信機（受信モジュール）とはシリアル（UART）で接続します。

#include "mbed.h"
#include "daisenRemote.h"

Serial pc(USBTX, USBRX);
DigitalOut myled(LED1);

daisenRemote remote(p10, daisenRemote::RF); // rx, type

void isrRemote () {
    pc.printf("Recv: %d\r\n", remote.read());
}

int main() {
    pc.baud(115200);
    pc.printf("*** REMOTE\r\n");
    remote.attach(isrRemote);
    for (;;) {
        led1 = ! led1;
        wait(0.2);
    }
}
