Can you guys help the bug from the code? I can’t run from Arduino IDE.
/*
Read both CCS811 and BME280 sensors at same time

License: This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license).
Works with SparkFun combo board https://www.sparkfun.com/products/14241
Enjoy this code? Buy a board and help support SparkFun!
Let’s read both sensors at the same time!
Outputs CO2, TVOC, temperature, humidty, and pressure.
Hardware Connections (Breakoutboard to Arduino):
Attach a Qwiic Shield to your RedBoard, Photon, or ESP32.
Plug the Qwiic Air Quality Combo board into one of the connectors
Serial.print it out at 9600 baud to serial monitor.
