Hello.
I'm trying to use a Spakrfun breakout board CCS811 with an Arduino Nano 33 BLE Sense but the code I'm trying from Spakrfun site is not even compilling!
The guide I'm using is this:
https://learn.sparkfun.com/tutorials/ccs811-air-quality-breakout-hookup-guide/all
The code I'm using is the one that returns the errors descriptions while starting the I2C bus, but without the interrupts and Wake Up features.
This is the exact code I'm trying to compile:
/******************************************************************************
WakeAndInterrupt.ino
Marshall Taylor @ SparkFun Electronics
April 4, 2017
https://github.com/sparkfun/CCS811_Air_Quality_Breakout
https://github.com/sparkfun/SparkFun_CCS811_Arduino_Library
This example configures the nWAKE and nINT pins.
The interrupt pin is configured to pull low when the data is
ready to be collected.
The wake pin is configured to enable the sensor during I2C communications
Hardware Connections (Breakoutboard to Arduino):
3.3V to 3.3V pin
GND to GND pin
SDA to A4
SCL to A5
NOT_INT to D6
NOT_WAKE to D5 (For 5V arduinos, use resistor divider)
D5---
|
R1 = 4.7K
|
--------NOT_WAKE

R2 = 4.7K

GND

Uses Wire.h for i2c operation

A utilizar a biblioteca SparkFun_CCS811_Arduino_Library com a versão 2.0.2 na pasta: C:\Users\cecol\Documents\Arduino\libraries\SparkFun_CCS811_Arduino_Library
A usar a biblioteca Wire na directoria: C:\Users\cecol\AppData\Local\Arduino15\packages\arduino\hardware\mbed_nano\3.2.0\libraries\Wire (legacy)
exit status 1
variable or field 'printDriverError' declared void
I don't know much about C++ to be able to fix the problem.
Can anyone help me?
Thanks
