Storing hours and minutes into single byte?

How about 60x24=1440 8 bits is 256 save time as 6 min chuncks 1440/6=240

for example

01:08 = 1x60/6 + 8/6 = 11 (time somewhere between 01:06 and 01:11)

23:59 = 23x60/6 + 59/6 = 239 (time somewhere between 23:55 and 24:00)


Clunky but it works provided you don't need better resolution.

You could use a word for HHMM, but nothing is stopping you from sharing some of the unused bits for other data.

Differentiation between 11:14 and 14:11 will be quite easy, because when time from RTC reaches that time, a variable is toggled, which can be later used to determine exactly what time should be read now.

If you can live with 2 second resolution then there are 43200 2-seconds per day -- one word.
