List of presets

Open EastEriq opened this issue 10 years ago • 1 comments

The attached script works on my radio; if saved as /mnt/debug/webserver/cgi-bin/radio_List_presets.cgi it naturally appears in the left frame of the welcome screen. Cosmetics may be improved, if you like it as a contribution, take.

Update: this is how far I've got for a tentative page handling presets. It interacts with the radio (one way) giving lirc commands. Nothing great, but being some 5 years late in the game... A more clever implementation could avoid refreshing the whole page (recalling the same cgi), which takes some seconds and kB of traffic, when buttons are pressed.

handle_presets.ZIP

Uses the script preset, included in the zip, which I dropped in /usr/sbin/.

Also included is an aborted attempt to command the spinner automatically entering a given string. Absolutely vane, only for future memory.
