After winning the contest i want to make some further improvements to the OSM4Primer2 project.

That is:
- a png decompressing algorithm to save space on the memorycard and to download OSM maps directly without the need to convert them to prm-files
- attach a hardware to the primer2 that can connect to the internet and download maps directly (even google maps)
- add routing capabilities

and more...

All proposal are welcome. Please visit the project website/ forum on

I'd love to see you attach an ethernet chip/wireless and see if that works. However, beware that wifi chips are harder.

Or you can bit bang ethernet.

Well, there are two ways to achieve this:

Connect a ethernet controller like the ENC28J60 to the STM32 and include the TCP/IP stack to the CircleOS. Unfortunatly there´s no free SPI left on the primer2.

Or connect a wifi module like this:

Advantage: TCP/IP stack already included. Only needs serialport and therefor can be connected to the extensionboard.

Note that SPI2 is available on the extension board. SPI2 is also used by CircleOS, but only for recording (as input) when the stw5094A is configured in voice mode. This mode is not used by default, and if you don't need the 'voice recording feature' in your application, you can use SPI2.
