Overview

There are two Grove interfaces in the SenseCAP Indicator for connecting Grove modules, one is the default I2C Port and other one is configurable Digital/Analog Pin, it can also be used for PWM outputs. Both Grove ports can be used as Digital.Providing more possibilities for developers.

This repo will introduce how to use the Grove IOs on the SenseCAP Indicator. This allows you to enjoy the plug and play functionality of the Grove Ecosystem as well as using the RP2040 compatible GPIO!

Grove(IIC)

To expand more applications, you can use the IIC interface to connect more sensors. Different with the built-in sensors, you only need to define the SCL and SDA pin connections.

Example Code:

This example code introduces how to connect a Grove TH sensor:

AHT20 temperature and humidity sensor library

#include <Arduino.h>
#include <Wire.h>
#include "AHT20.h"

AHT20 AHT;

void sensor_aht_init(void) {
  AHT.begin();
}

void sensor_aht_get(void) {
  float humi, temp;
  int ret = AHT.getSensor(&humi, &temp);
  if (ret)  // GET DATA OK
  {
    Serial.print("humidity: ");
    Serial.print(humi * 100);
    Serial.print("  temerature: ");
    Serial.println(temp);
  } else  // GET DATA FAIL
  {
    Serial.println("GET DATA FROM AHT20 FAIL");
  }
}

void setup() {
  Serial.begin(115200);

  Wire.setSDA(20);
  Wire.setSCL(21);
  Wire.begin();

  sensor_aht_init();
}

void loop() {
  sensor_aht_get();
  delay(5000);
}
