Saving frequencies for radio stations
I am definately no expert here, but I may be able to help a little bit. I have a very similar function with the buttons on my weather page. When pressed and held, the OSK asks for the city name, and writes that to the rr.ini file. WHen the value is in the ini, RR loads it automatically when RR starts. It will remain whatever freq it was, until the button is held and then updated in the ini.
Going this route, you will not have to have individual files for each preset.
"SETVAR;Preset1;$FREQUENCE$||SAVETOINI;Preset1;$FR EQUENCE$" (Purposely misspelled, as stated in the skincommands.txt file, for older Media Car Support)
I have not tested the line above, but it SHOULD work, (make sure to remove the space in FREQUENCE above that the forum inserted)
This would then save the following line in the rr,ini
To call that back up as a label on the button use:
Another advantage of this, is if you plan to make this skin public, then when the radio skin is opened for the first time, the presets will be blank, and all that would be required it to press and hold them to add the info to the rr.ini. No lines would have to be added manually
