Cleanup sensor data interface: In a very early implementation of the multiplexer the address of the mux was 0 followed by the sensors. As a resul the ID of the channels was shifted by one. To avoid confusion and because the mux address is meanwhile changed to the last address, it makes sense to return to the indexing where only the three visible sensor slots are used as reference (0,1,2).

# How to Create From Scratch a Project for _CPU2-RTE_ Code #

Follow the same procedure than for [CPU1](Detailed CPU1-Discovery Project.md), with changes:

- Create a new _board_ for processor:  
>   Series: `STM32F4`  
>   Mcu: `STM32F411xE`  
>   Debug: `JTAG`  

- Add `Small_CPU` linked source directory (instead of _Discovery_)

- Use linker script `OSTC4/Small_CPU/CPU2-F411.ld`
