alex	fd49235f9e	ui: implement a screen timeout after a period of user inactivity ... passed 60 sec of no touch screen activity, daemon turns off backlight and gui places a black "topdrop", opposite of backdrop. simply touching the screen reactivates it immediately. there seem to be no way to turn screen power off, so backlight plus black topdrop is the next best. there's no user settings to change 60 sec timeout at the moment because it is unclear whether it's worth adding UI elements. can always do so later. the implementation also provides means to reactivate the screen in an event of an alert from the daemon in the future. closes #3	2 years ago
alex	fe68ae96d6	comm: format protocol header manually and eliminate a potential footgun ... the nd/ngui protocol is a simple TLV: message tag, length and a json-encoded payload. the issue is with the (tag, length) header which was written/read by using raw memory pointers, such as Writer.writeStruct. in addition, tag ordinal values were auto-generated by the compiler. all those deficiencies may potentially lead to bugs hard to find or serious data leaks. serializing and deserializing the (tag, length) header manually makes it more robust and eliminates the footgun.	2 years ago
