Expanded Sensor map structure: In the previous version the number of possible sensors were set to 5 based on the assumption that ADC slots are shared with digital O2 sensors. As result three of five slots would have been limited to O2 measurement usecase, leaving just two slots left for other sensors (e.g. CO2). In order to have as much flexibility (and less risk for data structure changes) the number of sensors has been set to 7 (3 ADC + 4 UART MUX)

# 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`
