Bootloader use compressed fonts:
The previous Bootloader was larger than 128k => not fitting into the first sectors of the second flash bank. Most memory is occupied by the two fonts in use. In order to make the bootloader small enough for the bootloader update function the fonts need to be compressed. To avoid code changes in visualization functions the compressed fonts are decompressed into RAM and then used in the same way as before.

# 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)
