I have 16 bit addresses stored in 2 sequential eeprom addresses, and I want to combine them into a 16 bit word, to address a max7219 chip.
I thought there was a method that used 'highbyte' and 'lowbyte', but I can't find anything about it.
instead of combining the 2 bytes into a word, can I just pass them together as 2 variables to the max7219?
So b1 = 00001000, b2 = 01000001;
address would need to be 0000100001000001
so send (b1, b2) to max7219?
I'm sure I've done this before, but probably only once, and I seem to have deleted it from my HD.
