4. Unit 8 encoder

Unit 8 encoder

  • K

    Hi

    Im trying to use the unit 8 encoder with M5 Paper. I want to get the LED to change colour with pressing the rotary dial in using getbuttonstatus. I have managed to record the button press however it returns to its previous state without repressing the button. Any advice where Im going wrong?

    Here is my code:

    #include "UNIT_8ENCODER.h"
    #include <M5EPD.h>

    UNIT_8ENCODER sensor;
    M5EPD_Canvas canvas(&M5.EPD);

    int32_t encoder[8] = {0};
    uint8_t btn_status[8] = {0};

    void show_encoder_value(void) {

    for (int i = 0; i < 8; i++) {

        btn_status[i] = sensor.getButtonStatus(i);
      encoder[i] = sensor.getEncoderValue(i);

    }
    if (btn_status[i] ==true) {
    sensor.setLEDColor(i, 0x00ff00);
    }
    else {
    sensor.setLEDColor(i, 0xff0000);
    }
    }
    }

    void setup() {
    sensor.begin(&Wire, ENCODER_ADDR, 25, 32, 100000UL);
    M5.begin(true,true,true,true,true);
    M5.RTC.begin();
    M5.EPD.SetRotation(90);
    M5.EPD.Clear(true);
    canvas.createCanvas(540, 960);
    }

    void loop() {
    // put your main code here, to run repeatedly:
    show_encoder_value();

    canvas.setTextSize(3);

    canvas.drawString(String(encoder[0]), 60, 30);
    canvas.drawString(String(encoder[1]), 125, 30);
    canvas.drawString(String(encoder[2]), 190, 30);
    canvas.drawString(String(encoder[3]), 255, 30);
    canvas.drawString(String(encoder[4]), 60, 60);
    canvas.drawString(String(encoder[5]), 125, 60);
    canvas.drawString(String(encoder[6]), 190, 60);
    canvas.drawString(String(encoder[7]), 255, 60);

     canvas.drawString(String(btn_status[0]), 60, 130);
canvas.drawString(String(btn_status[1]), 125, 130);
canvas.drawString(String(btn_status[2]), 190, 130);
canvas.drawString(String(btn_status[3]), 255, 130);
canvas.drawString(String(btn_status[4]), 60, 160);
canvas.drawString(String(btn_status[5]), 125, 160);
canvas.drawString(String(btn_status[6]), 190, 160);
canvas.drawString(String(btn_status[7]), 255, 160);
canvas.pushCanvas(0, 0, UPDATE_MODE_DU4);

    delay(100);

    }

    Thanks

    David
