Basic usage

Grove - Gesture

get gesture model.

grove.onGesture(GroveGesture.Up, () => {
    basic.showString("Up");
})
grove.onGesture(GroveGesture.Down, () => {
    basic.showString("Down");
})


grove.initGesture()
basic.forever(function () {
    if (grove.getGestureModel() == 1) {
        basic.showLeds(`
            . . # . .
            . . . # .
            # # # # #
            . . . # .
            . . # . .
            `)
    }
    if (grove.getGestureModel() == 2) {
        basic.showLeds(`

Grove - Ultrasonic Ranger

Measure distance in centimeters, specify the signal pin.

let distance = grove.measureInCentimeters(DigitalPin.P0);

Measure distance in inches, specify the signal pin.

let distance = grove.measureInInches(DigitalPin.P0);

Grove - 4 digital display

Create a 4 Digital Display driver, specify the clk and data pin, and set the brightness level, then start display value.

let display = grove.createDisplay(DigitalPin.P0, DigitalPin.P1);
display.set(7);
display.show(1234);

Use ||bit|| to display one bit number.

Use ||point|| to open or close point dispay.

Use ||clear|| to clean display.

Grove - UART WiFi V2

Connect to a WiFi and send data to ThinkSpeak or IFTTT, specify the UART tx and rx pin.

grove.setupWifi(
    SerialPin.P15,
    SerialPin.P1,
    BaudRate.BaudRate115200,
    "test-ssid",
    "test-passwd"
)

basic.forever(() => {
    if (grove.wifiOK()) {
        basic.showIcon(IconNames.Yes)
    } else {
        basic.showIcon(IconNames.No)
    }
    grove.sendToThinkSpeak("write_api_key", 1, 2, 3, 4, 5, 6, 7, 8)
    grove.sendToIFTTT("ifttt_event", "ifttt_key", "hello", 'micro', 'bit')
    basic.pause(60000)
})

Grove - LCD 16x2

Show string and number after initialize LCD.

grove.lcd_init()
grove.lcd_show_string("Hello", 0, 0)
grove.lcd_show_number(12345, 0, 1)

Grove Temperature & Humidity Sensor (DHT11)

Read the temperature and humidity from the Grove Temperature & Humidity Sensor.

serial.redirectToUSB();

let dht11 = grove.connectToDHT11(DigitalPin.P1, false);

basic.forever(function () {
    if (grove.readTemperatureHumidity(dht11)) {
        serial.writeLine("New data received:");
        serial.writeValue("humidity", grove.getHumidity(dht11));
        serial.writeValue("temperature", grove.getTemperatureCelsius(dht11));
    } else {
        serial.writeLine("Fail to read, try again later");
    }
    basic.pause(2000);
})

Grove - Vision AI Module V2

Connect the Grove Vision AI Module V2 through I2C and get AI inference results.

grove.onReceiveDetectionResult(function (detectionResults) {
    for (let detectionResult of detectionResults) {
        serial.writeLine(detectionResult.toString())
    }
})

let persons = 0

serial.redirectToUSB()
grove.connectAndSetupGroveVisionAIV2(true)

while (!(grove.startAIInference())) {
    serial.writeLine("Failed to start inference")
    basic.pause(1000)
}

basic.forever(function () {
    if (grove.fetchAIInferenceResults()) {
        serial.writeLine("Fetch inference result success")
        if (grove.containsObjectName(["person"])) {
            persons = grove.countObjectByName(["person"])
            serial.writeString("Detected persons: ")
            serial.writeNumber(persons)
            serial.writeLine("" + ("\n"))
        }
    }
    basic.pause(100)
})
