Description
I'm trying to compile the code from this post:
https://learn.sparkfun.com/tutorials/ccs811-air-quality-breakout-hookup-guide/all
without the interrupts and Wake Up features to try to read the values from CCS811 over I2C but the code is not even compilling. I'm getting this error:
Temp_Hum_Gas_rasp:125:36: error: variable or field 'printDriverError' declared void
void printDriverError( CCS811Core::status errorCode ){

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

The code I'm trying is exactly this:

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

Uses Wire.h for i2c operation

Am I missing something or what is the problem is the status not being a member of CCS811Core?
I'm using Arduino Nightly 1.8.20 and Windows 10 (at work).
