Bugfix ppo2 display in simulator mode: In the previous version a wrong ppo2 value was display if a digital O2 sensor was used. Rootcause was that the calibration data of the analog sensors was used. To fix this a default calibration coefficient is used (calibration is done within the sensor => no need to store it in OSTC) if the sensor is identified as digital O2 sensor.

# How to Create From Scratch a Project for _CPU1-Upper_ Code #

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

## Make a specific project ##

Follow the same procedure than for [CPU1-Discovery](Detailed CPU1-Discovery Project.md), (same processor, same includes) but include the `CPU1-Upper` source directory.
