### build
Run `make` to build demo programs `bme680_spi` and `bme680_i2c` that use the pins/dev configured in `spi.c` and `i2c.c`
```sh
$ make
```
This will create demo programs `bme680_i2c` and `bme680_spi`, and logging programs `bme680_log_i2c` and `bme680_log_spi`. They all expect the pin/devices specified in `spi.c` and `i2c.c`.
Also `make log` creates spi and i2c versions of the log program
The loggers spit out the following every minute:

>Note: disregard measured gas resistance if the heat stability bit is not 1.
