It bought it with KYOHRITSU of Osaka.

RDCM-802

 

Class library for RDCM-802 was here.

RDCM802

 

Sample program was here.

#include "mbed.h"
#include "TextLCD.h"
#include "RDCM802.h"

DigitalOut myled(LED1);

TextLCD lcd(p8, p12, p15, p16, p29, p30, TextLCD::LCD16x2); // rs, e, d0-d3

RDCM802 Compass(p18 /* D0 */, p19 /* D1 */, p20 /* D2 */);
int main() {
    int nowCompass;
    while(1) {
        lcd.cls();
        lcd.locate(0,0);
        nowCompass = Compass;
        lcd.printf("COMPASS:0x%04x\n",nowCompass);
        lcd.printf("[%s]\n",Compass.toString());
        myled = 1;
        wait(0.2);
        myled = 0;
        wait(0.2);
    }
}

Attention

There seems to be something to which the D0 bit and the D2 bit are written oppositely when retrieving it with Web.

For example, D0 is opposite to D2 in these two Web pages.

The class library that I wrote is processed by the row of this table.

N NE E 
SE S SW W NW
D0 1 0 0 0 0 1 1 1
D1 1 1 1 0 0 0 0 1
D2 0 0 1 1 0 0 1 1
