So time is up!
Here is the presentation video:
Currently working features:
- FM radio receiver
- FM frequency adjusting and editing
- setting volume
- RTC time display
- RTC time setting
- 24 7-segment characters and 20 14-segment displays
What didn't make it to the build in time:
- a few more buttons
RDS was really problematic. As explained in the video, I didn't manage to receive any kind of information from Si4703 Arduino library from Sparkfun. It seems it has a very limited support and unfortunatly blocking function calls (like lose keypad responsivness for 15 seconds awaiting for RDS data). I hope I'll be able to add this feature later.
Alarm and more buttons was simply a matter of time, which we run out of. Nothing difficult there, just some additional work. As for the casing, it other than little time we had, we thought it's safer to make the casing (or in this case front panels) out of wood, as it is easyer to work with. We had silver paint to pain it, but we run into lots of hardware bugs while testing all hardware connected together (first time 10 hours before this video recording). A good example is the LED connected to pin 13 of Arduino that prevented the Keypad library to work properly with the pins for the keypad we chose - so we removed it :)
There is ofcourse a lot more we would have wanted to do, but I guess we will need to leave it for later.
The contest was a lot of fun and I hope there will be more!
