micro:bit Gateway

Ferdinand Stueckler

Mayelana nalolu hlelo lokusebenza

Lolu hlelo lokusebenza usungula isiteshi phakathi ezimbili ezincane: amadivayisi bit. Isiteshi uzobe handeled njengoba UART zokuxhumana. Kufanele develope a sohlelo on ngalinye micro: bit idivayisi ngokudluliselwa UART.

Okubonisa aktive: Okubonisa nakali (Okuzenzakalelayo)
Okubonisa inaktive: Isaziso nakali

aktive Silent: Ayikho ukugawulwa kwemithi sibonwa
inaktive Silent: Imithi

Izidingo:
- Min. Android 4.4
- Bluetooth Low Energy (BLE)
- Imishini ebhangqiwe
- Micro: bit sohlelo (lakhiwa ngokwakho)


Isibonelo MBED:

#include "MicroBit.h"
#include "MicroBitUARTService.h"

MicroBit uBit;
MicroBitUARTService * uart;

int axhunyiwe = 0;

yize onConnected (MicroBitEvent e)
{
    uBit.display.scroll ( "C");
    
    exhunywe = 1;
}

yize onDisconnected (MicroBitEvent e)
{
    uBit.display.scroll ( "D");
    exhunywe = 0;
}

yize onButtonA (MicroBitEvent e)
{
    uma (== exhunywe 0) {
        uBit.display.scroll ( "NC");
        buyela emuva;
    }
    uart-> thumela ( "Yebo");
    uBit.display.scroll ( "Y");
}

yize onButtonB (MicroBitEvent e)
{
    uma (== exhunywe 0) {
        uBit.display.scroll ( "NC");
        buyela emuva;
    }
    uart-> thumela ( "Cha");
    uBit.display.scroll ( "N");
}

yize onButtonAB (MicroBitEvent e)
{
    uma (== exhunywe 0) {
        uBit.display.scroll ( "NC");
        buyela emuva;
    }
    uart-> thumela ( "SK");
    uBit.display.scroll ( "SK");
}

zintula processBLEUart () {
    uint8_t readBuf [22];
    kanti (1) {// loop kuze kube phakade
        uma ((! exhunyiwe) || (! uart-> isReadable ())) {
            uBit.sleep (50); // Ulinde 50mS ubuye ukhangele njalo
            qhubeka; // Loop;
        }
        // Futhi sisuke axhunyiwe KANYE kukhona abanye input ukufunda
        uma (uart-> isReadable ()) {
            kanti (uart-> isReadable ()) {
                int charCount = uart-> ukufunda (readBuf, 22, Vumelanisa);
                uma (charCount! = 0) {
                    ngoba (int i = 0, i                         uBit.display.scroll ((Isakare) readBuf [i]);
                }
            }
        }
    }
}

OKUBALULEKILE !!!
Oherwise uyobe uphelelwa inkumbulo!

Ncoma ivimbele DFU kanye Izinkundla namasevisi e MicroBitConfig.h ngoba alidingeki lapha:
