uses for the first times a wio GPS Boarders

Products & Technology Wio Series
#1

Hi everybody,

I am using a wio GPS Boarder for the first time. I did all the procedure described on seed’s website to configure wio with arduino IDE but when compile my code (for temperature and humidity sensor) , a lot of time it shows that the croquits can’t be compiled and sometimes it shows compilation finish but I can’t see the result in Serial monitor.



I am using windows 10, and just the USB not battery to power the boarder.



have someone already resolve this kind of problem or if someone how to resolve it , please a need your help.

Hi there~



Please post the software code. For the Serial print, you have to use SerialUSB.print instead of Serial.print due to it using SAMD21 chip. thanks.

// Example testing sketch for various DHT humidity/temperature sensors

// Written by ladyada, public domain



#include “DHT.h”



#define DHTPIN 2 // what pin we’re connected to



// Uncomment whatever type you’re using!

#define DHTTYPE DHT11 // DHT 11

//#define DHTTYPE DHT22 // DHT 22 (AM2302)

//#define DHTTYPE DHT21 // DHT 21 (AM2301)



// Connect pin 1 (on the left) of the sensor to +5V

// Connect pin 2 of the sensor to whatever your DHTPIN is

// Connect pin 4 (on the right) of the sensor to GROUND

// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor



DHT dht(DHTPIN, DHTTYPE);



void setup()

{



Serial.begin(9600);

Serial.println(“DHTxx test!”);



/if using WIO link,must pull up the power pin./

// pinMode(PIN_GROVE_POWER, OUTPUT);

// digitalWrite(PIN_GROVE_POWER, 1);



dht.begin();

}



void loop()

{

// Reading temperature or humidity takes about 250 milliseconds!

// Sensor readings may also be up to 2 seconds ‘old’ (its a very slow sensor)

float h = dht.readHumidity();

float t = dht.readTemperature();



// check if returns are valid, if they are NaN (not a number) then something went wrong!

if (isnan(t) || isnan(h))

{

SerialUSB.println(“Failed to read from DHT”);

}

else

{

SerialUSB.print(“Humidity: “);

SerialUSB.print(h);

SerialUSB.print(” %\t”);

SerialUSB.print(“Temperature: “);

SerialUSB.print(t);

SerialUSB.println(” *C”);

}

}







hello, everything is fine with the code but when I try to upload it gives me port error.

Hi there~




  1. Please change the below serial to serialusb.

</s>Serial.begin(9600); Serial.println("DHTxx test!"); <e>

  1. If you can not find the port, you can double tap the reset button. thanks.
