I bought this board primarily since it had Qwiic connector port as well as wifi but it is not working with the Sparkfun sensors. It loads the sketch without problems or errors but does nothing. Using the same cable and sensor with the Sparkfun Redboard it works fine. Will we have to wait for new libraries?
which sensor are you using?
I tried both the Qwiic Twist and Qwiic RTC. Both work with the RedBoard
I'm experiencing the same problem. I tried an Adafruit Qwicc AHT20 Temperature/Humidity sensor. The sensor is not detected.
The Qwicc AHT20 sensor is working fine with both Adafruit Metro M4 Express and a Node MCU 1.0 (ESP-12E) boards.

I started off simple and tried one of the Sparkfun Quiic buttons, and
And I tried the Example2_LightWHenPressed example sketch.
The unmodified sketch did not work. But I remembered that the Qwiic connector is on the Wire1 buss, not the default Wire buss.
So I updated the sketch:

#include <SparkFun_Qwiic_Button.h>
QwiicButton button;
uint8_t brightness = 100; //The brightness to set the LED to when the button is pushed

void setup() {
Serial.begin(115200);
Serial.println("Qwiic button examples");
Wire1.begin(); // ******* QWIIC is on Wire1 ***
//check if button will acknowledge over I2C
// On Wire1
if (button.begin(SFE_QWIIC_BUTTON_DEFAULT_ADDRESS, Wire1) == false) {
Serial.println("Device did not acknowledge! Freezing.");
while (1);
}
Serial.println("Button acknowledged.");
//Start with the LED off
button.LEDoff();
}
void loop() {
//check if button is pressed, and tell us if it is!
if (button.isPressed() == true) {
Serial.println("The button is pressed!");
button.LEDon(brightness);
while(button.isPressed() == true)
delay(10); //wait for user to stop pressing
Serial.println("The button is not pressed.");
button.LEDoff();
}
delay(20); //Don't hammer too hard on the I2C bus
}
Changed the Wire1.begin() and the button.begin() lines to use Wire1
Qwiic button examples
Button acknowledged.
The button is pressed!
The button is not pressed.
The button is pressed!
My guess is this is the issue with several others in this thread as well
EDIT: Also tried a Qwiic BMP388 Pressure Sensor (now retired)... again I had to edit the sketch to work with Wire1 and in this case I had to edit the begin method to pass in the I2C Address.

You got it! Changing to Wire1 in both the Qwiic Twist and RTC sketches got them working. Thanks! Ifeel justified in buying this now. I love the fact you can chain devices together and now I can use my breadboards for slicing my tiny loaves!
KurtE, thanks! That was it. My Qwicc AHT20 sensor is now working!
In addition to:
Wire1.begin( );
I had to change:
aht.begin( );
to
aht.begin( &Wire1 );

Thinking that other Sparkfun Qwiic devices will now work using the Wire1 trick, I purchased the Temperature and PIR sensors. Unfortunately this is not the case. A posting to the Sparkfun forum told me that you also need to point it to the correct pin #s but gave no details about how to do this. Any ideas?
Which device? Which software library… code you are running
It is the SparkFun_STTS22H.h library for the SparkFun Temperature Sensor - STTS22H (Qwiic). It works fine on the RedBoard. I tried the examile1-basic sketch
Sorry I don't have this device... I don't think... I did not have that library installed
But looks like it should work... IF...
void setup()
{
Wire1.begin();
Serial.begin(115200);
if( !mySTTS.begin(Wire1) )
{
Serial.println("Did not begin.");
while(1);
}
Serial.println("Ready");
With the two lines changed that have the word Wire1 in it.

No, I tried that before.
There are 2 lines in the library file:
// wirePort optional. The Wire port. If not provided, the default port is used
// address optional. I2C Address. If not provided, the default address is used.
Does this mean that I need to add these to the sketch since it was written for Wire not Wire1?
If so, What would they look like?
I figured it out, just in setup, in the begin() function of the sensor, there is needed information about Wire1.
#include <Wire.h>
#include <SparkFun_TMP117.h>
TMP117 sensor;
void setup() {
Wire1.begin();
Serial.begin(115200);
sensor.begin(0x48, Wire1);
}
void loop() {
Serial.println(sensor.readTempC());
delay(1000);
}
Yes, that worked. In my case with the sensor I own the code is:
#include <Wire.h>
#include "SparkFun_STTS22H.h"
SparkFun_STTS22H mySTTS;
float temp;
void setup()
{
Wire1.begin();
Serial.begin(115200);
mySTTS.begin( Wire1);
It does not need the address 0x48 for some reason. Thank you very much
Hello again,
I have just got a LISMDL with a view to working through calibration of a Magnetometer.
Using the LIS3MDL demo example I have finally got it working with Uno R4 Wifi using Qwiic ( on LISMDL) with wire pins SCL, SDA, 5v, and Gnd to R4 header.
I have followed this thread and I cannot seem to get it to work Qwiic to Qwiic.
Serial monitor output:-
Adafruit LIS3MDL test!
Failed to find LIS3MDL chip
I tried Wire Wire1: , Wire1.begin(): and changing
if (! lis3mdl.begin_I2C()) { // hardware I2C mode, can pass in address & alt Wire
to
if (! lis3mdl.begin_I2C(Wire1)) { // hardware I2C mode, can pass in address & alt Wire
and various other options but it will not compile.
Error:-

You might try:

Worked a treat! Thanks
Looking back I had tried the (LIS3MDL_I2CADDR_DEFAULT, Wire1), and it didn't compile, sort of guessed it by looking at the .cpp and .h files; (i2c_address, wire) but did not know the '&' was needed. Still don't know why.
My programming knowledge is very basic.
Glad it worked.
The language syntax can be very confusing. I have used it for years, but there are some of the new things, that I have to look up... Like lambda stuff or templates...
But in this case the error message gave the hint. From your first post:
An object can be passed in three ways (object, pointer to object, reference to object)
By pointer: something like, by pointer as this one is: TwoWire*
The * is the key... So it wants you to pass it a pointer, which you get with an &
so &Wire1
Some do by reference: The definition would have been: TwoWire&
The & is key, To pass one you simply pass: Wire1
An object: would have been just: TwoWire
And I doubt would work...
Good luck.

Thank you.
thanks for all those info guys.
i have the same kind of issues on a BNO085 from adafruit.
i use the quaternion template and edited as you did for your qwiic sensors but no luck for me :
the edited code :
void setup(void) {
Wire1.begin();
Serial.begin(115200);
while (!Serial) delay(10); // will pause Zero, Leonardo, etc until serial console opens
Serial.println("Adafruit BNO08x test!");
if (!bno08x.begin_I2C(74,&Wire1)) {
//if (!bno08x.begin_UART(&Serial1)) { // Requires a device with > 300 byte UART buffer!
//if (!bno08x.begin_SPI(BNO08X_CS, BNO08X_INT)) {
Serial.println("Failed to find BNO08x chip");
while (1) { delay(10); }
}
Serial.println("BNO08x Found!");
setReports(reportType, reportIntervalUs);
Serial.println("Reading events");
delay(100);
}
the result :

16:45:10.276 -> I2C address not found
