Mission in a huge company leader in the auto radio development. I had to develop in C language a GUI autoradio system based on an XML description. The process was simple : The XML description was stored in a SQLite database from a C# tool I wrote, then this database was used to generate some C datas ( written in C# too) and finally I wrote a generic engine running on the embedded platform which use those datas to render the HMI. The generic engine had to run on the TI processor : TMS 470, but the rendering requests were made by a simple exchange protocol between the TMS and a FPGA.
