Improve CO2 calibration:
The most common calibration environment for diving is fresh air => ~400ppm co2. Some sensors do not have this setting as default => Calibration to 0ppm. To make sure that a proper calibration reference is set the common used value of 400ppm is not set before starting the calibration. For implementation new states were added to the co2 protocol state maschine. In addition the rx processor is now able to handle two responds parameters.

# Using OpenSTM32 IDE to Compile OSTC4 Firmware # The free and Open [STM32 IDE](http://www.openstm32.org/System%2BWorkbench%2Bfor%2BSTM32) is an integrated development environment based on _Eclipse_ that will allows you to compile and link code for the OSTC4 dive computer. You will then be able to generate `.bin` firmware files to upload to your computer using your favourite tools, eg. [OSTC Companion](https://ostc-planner.net/companion). 1. Register on http://www.openstm32.org/ : that will allows you to download the IDE. 2. Once registered and logged in, you can go to _Documentation_ and _Installation Manual_. Follow the instructions to install the IDE (available for Windows 7, MacOS and Linux). 3. Use the ready made project ... in ... Or you can create a brand new project by following the _How To_'s: - [HowTo compile CPU1-Discovery main firmware](Detailed CPU1-Discovery Project.md) - [HowTo compile CPU1-Discovery protected area firmware](Detailed CPU1-Upper Project.md) - [HowTo compile CPU2-RTE real-time firmware](Detailed CPU2-RTE Project.md) - [HowTo generate uploadable firmware file](Make Firmware File.md)
