Always use polling mode for CO2 operation:
In the previous version the CO2 sensor was operated in streaming mode (2 measurements a second) in case it was used stand alone (without multiplexer). This added some complexity to the implementation (setup, error handling etc). To reduce this the sensor will now always be operated in polling mode like it is done for multiplexer operation. To make sure that the correct mode is set a command has been added to the configuration steps.

3 The main CPU (aka. _CPU1 Discovery_) firmware is splitted in two parts:
|
|
|
4 - The proper _CPU1 Discovery_ firmware, with the main code.
|
|
|
5 - The _protected upper memory_ firmware, which is programmed during _OSTC4_ production, and contains (amongst other things) code used to upload and install firmware upgrades.
