i2c_bus or just i2c?

I had i2c. Must have pasted the wrong update at some point in going back and forth between code.py and simpletest.

ccs811 = adafruit_ccs811.CCS811(i2c_bus)

#wait for the sensor to be ready and calibrate the thermistor
while not ccs.data_ready:
# Wait for the sensor to be ready and calibrate the thermistor
while not ccs811.data_ready:
pass
temp = ccs.temperature
ccs.temp_offset = temp - 25.0
temp = ccs811.temperature
ccs811.temp_offset = temp - 25.0

while True:
print("CO2: ", ccs.eco2, " TVOC:", ccs.tvoc, " temp:", ccs.temperature)
time.sleep(.5)
print("CO2: %1.0f PPM, TVOC: %1.0f PPM, Temp: %0.1f C" %
(ccs811.eco2, ccs811.tvoc, ccs811.temperature))

Should we use .format here instead of %? I think % is considered the "old" way.

Hmm I didn't realise it was considered to be the old way. I'll refactor it.

time.sleep(0.5)
