How to display more than 65536 with MAX7219
Hi All
would someone be kind enough to explain to me how i can display more than
65536 which is the limit of a word variable on a 7 seg display using the Max7219 and 6 digits.
i want to be able to display say 123456 but this a more than a word

Any pointers would be well appreciated

It might be a decade delayed answer, but here is what op needs:
To display any digit at any position on MAX7219, which can drive up to 8 digit 7 segment displays. Without sending actual number to that IC.
The problem is, that all existing "code samples" for PBP are meant to decode value of some variable into corresponding reading of MAX7219 display. And without "LONG", we are limited to 65535.
Due to that, I've almost completed a code, which will like this: There are two variables, MPOS, MVAL. First one stands for position on 8 digit display (0-7), and 2nd one is actual number you want to display there. So to display say 00876540, the code will look like this
Code:
MPOS=7
MVAL=0
GOSUB DSP
MPOS=6
MVAL=0
GOSUB DSP
MPOS=5
MVAL=8
GOSUB DSP
and so on.
