Re: wiringPiISR switch bounce

IMHO, debouncing is best done in hardware, if you're up for that. Two NAND gates, two pull-ups and a SPDT switch are all that is required. Then no software shenanigans are necessary.

Just one tip to try before you give up on lo-res displays: - if a settings dialog window (or any window for that matter) has its lower part off-screen (especially the OK button) then hold down the ALT key (to the LEFT of the space bar) and use the mouse to drag an otherwise immovable settings window...

Re: How do I add a headphone jack?

It depends on the audio circuitry in the LCD Controller, but probably NOT. And doing so will most likely damage that circuitry in the LDC Controller permanently. Sorry. (As drgeoff said.)

Re: RTC not found

I don't think the Pi has a RTC. In its unexpanded form, it only reads the RTC from a network time server AFTER it's been connected to the Internet. However, there are stand-alone RTC peripherals available - that tend to have small power cells and RTC chips on a HAT or similar. Look here: https://www...
