//////////////////////////////////////////////////////////////////////////////////////////////////////////

// This is basic example to use the K30 sensor with Feather.
// The K30 sensor will measure the CO2 from the range 0 to 10000 ppm and log to SD.

// In this example of program, it will measure the CO2 level and display on the Serial Monitor.
// Note that the K30 sensor needs at least 6 minutes of warm up to get accurate measurements.
// Therefore, you will get data values after 6 minutes have passed.
// Inside this program, there is a timer that will run for 6 minutes before it starts measuring values.

// As you might see, there are some syntax that came from outside of the Loom language,
// so take a look the link and the code carefully.

First issue "Cannot add null module" has been fixed by changing a line in Loom's K30.h. Changing the registration function call at the bottom of the file from REGISTER_NODEFAULT() to REGISTER() fixes that issue. The config.h file being worked with above attempts to add the K30 module with 'default' parameters, though this cannot be done when the module is register with REGISTER_NODEFAULT().

@SmithJar-rov , please test by Week 5 meeting - if enough time with K30 hardware arriving.

Issue: pins were not correctly connected on the K30
