Changed reaction for uart DMA buffer overruns: In the previous version a DMA was not restarted in case the read pointer is in the chunk which should be filled next. In normal operation this should never happen, in special cases, like debugging, it may occure. In case of an overrun the data may be already outdated and can be discarded. Because of this the new handling of a buffer overflow is to set the read pointer to the start of the chunk => the read function will start with the latest received data. Not yet processed data will be discarded.

# 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)
