micro:bit Gateway

Ferdinand Stueckler

Kuhusu programu hii

Programu hii itaanzisha channel kati ya mbili ndogo: vifaa bit. Channel itakuwa handeled kama UART mawasiliano. Una kuendeleza programm juu ya kila micro: bit kifaa na UART uhamisho.

Dalili aktive: ble Dalili (Default)
Dalili inaktive: ble Notification

Kimya aktive: No magogo Visual
inaktive kimya: Logging

mahitaji:
- Min. Android 4.4
- Bluetooth Nishati Chini (ble)
- Vifaa Paired
- Micro: bit programm (zilizotengenezwa na wewe mwenyewe)


mfano MBED:

# Pamoja "MicroBit.h"
# Pamoja "MicroBitUARTService.h"

MicroBit ubit;
MicroBitUARTService * UART;

int kushikamana = 0;

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

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

utupu onButtonA (MicroBitEvent e)
{
    kama (kushikamana == 0) {
        uBit.display.scroll ( "NC");
        kurudi;
    }
    uart-> kutuma ( "Ndiyo");
    uBit.display.scroll ( "Y");
}

utupu onButtonB (MicroBitEvent e)
{
    kama (kushikamana == 0) {
        uBit.display.scroll ( "NC");
        kurudi;
    }
    uart-> kutuma ( "No");
    uBit.display.scroll ( "N");
}

utupu onButtonAB (MicroBitEvent e)
{
    kama (kushikamana == 0) {
        uBit.display.scroll ( "NC");
        kurudi;
    }
    uart-> kutuma ( "SK");
    uBit.display.scroll ( "SK");
}

utupu processBLEUart () {
    uint8_t readBuf [22];
    wakati (1) {// kitanzi milele
        kama ((! kushikamana) || (! uart-> isReadable ())) {
            uBit.sleep (50); // Kusubiri 50mS na kuangalia tena
            kuendelea; // Kitanzi;
        }
        // Kingine sisi ni kushikamana NA kuna baadhi ya pembejeo kusoma
        kama (uart-> isReadable ()) {
            wakati (uart-> isReadable ()) {
                int charCount = uart-> kusoma (readBuf, 22, async);
                kama (charCount! = 0) {
                    kwa (int i = 0; i                         uBit.display.scroll ((Char) readBuf [i]);
                }
            }
        }
    }
}

MUHIMU !!!
Oherwise utakuwa kukimbia nje ya kumbukumbu!

Kupendekeza mlemavu DFU na Tukio huduma katika MicroBitConfig.h tangu wao si zinahitajika hapa:

int kuu ()
{
    // Initialise micro: bit Runtime.
    uBit.init ();

    uBit.messageBus.listen (MICROBIT_ID_BLE, MICROBIT_BLE_EVT_CONNECTED, onConnected);
    uBit.messageBus.listen (MICROBIT_ID_BLE, MICROBIT_BLE_EVT_DISCONNECTED, onDisconnected);
    uBit.messageBus.listen (MICROBIT_ID_BUTTON_A, MICROBIT_BUTTON_EVT_CLICK, onButtonA);

    uBit.messageBus.listen (MICROBIT_ID_BUTTON_AB, MICROBIT_BUTTON_EVT_CLICK, onButtonAB);


    UART = mpya MicroBitUARTService (* uBit.ble, 32, 32);
    uBit.display.scroll ( "Nenda");
    create_fiber (& processBLEUart); // Kuunda nyuzi na ratiba yake.
