Discovery<=>SmallCPU inferface update: The sensor data struct is extended to store the data of up to three (three visible O2 sensors). To avoid unnecessary payload on the SPI only the last update sensor data item is transfered. The sender receiver uses the sensor ID which is provided in parallel to identify the correct storage location.

# 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.
