Is it possible to use the grove color sensor v1.3 with Arduino Nano RP2040?

Using Arduino Sensors
1

So this is the code:

#include <WiFiNINA.h>
#include <Wire.h>
#include <GroveColorSensor.h>


int red, green, blue;
GroveColorSensor cS;

void setup() {

  Serial.begin(9600);
  Wire.begin();


  
}

void loop() {
  cS.readRGB(&red, &green, &blue);
  Serial.print("The RGB value are: RGB( ");
  Serial.print(red,DEC);
  Serial.print(", ");
  Serial.print(green,DEC);
  Serial.print(", ");
  Serial.print(blue,DEC);
  Serial.println(" )");
  delay(500);
  cS.clearInterrupt();
  delay(500);

}

The problem is that when I upload it the Arduino crashes (3 short 3 long blinks of the onboard LED in a loop). Why is that?

Could you please post your wiring diagram?

Can you please post a link to the specs for "grove color sensor v1.3"

If you upload the blink example sketch, does that work?

it works with everything else, but the moment I add the GroveColorSensor.h library it stops working. This is the color sensor im talking about.

Arduino | Color sensor
5V | VCC
GND | GND
A5 | SCL
A4 | SDA

Have you tried any other I2C devices with your NanoRP2040?
Are the SDA and SCL pins assignments correct for your Nano?

7

Are you using the correct library for the version of the board you have? The Seeed page you linked to mentions only versions 1.2 and 2.0.

Have you tried the i²c scanner sketch?

Have you tried another Arduino, such as an Uno?

Have you requested help on on the Seeed forum?

I have used it with an Uno and it worked, so that's a problem with the rp2040 nano. I can't find the V1.3 version, but it looks perfectly like the 1.2, and in the shop where I bought it they said it should be used like the 1.2.
I will try the i2c scanner once I get home
I havent asked on the seed forum yet, but I think if nothing comes out of here im going to do it.

Try connecting Vcc of the sensor to 3.3V, not 5V.
