fonts.h file basics?

Postby Wermz » Sat Feb 25, 2017 2:31 pm

Sorry for the really noobish post. I am trying to figure how the static words and letters in kit three are displayed on screen? "RPM" "Temperature" etc.

Can somebody explain how the fonts.h file works? or point me to a website with good explanations. I've been trying to search for info for a couple of days now to no luck.

Looks like it does some sort of hex conversion for each letter and character, but i see several values per character let's say the letter R for example has this
" { 0x7f, 0x09, 0x19, 0x29, 0x46 }, // 52 R"
in searching for this i do not see 0x7f, 0x09, 0x19, 0x29, 0x46 as a string anywhere.
I do see 0x07f in a couple of locations.

What do the five hex numbers in front of each character mean? and how does it work?

thanks.
