Hello there ,I like to display a moving message on 3 8*8 dot matrix (ROW Anode) but I am having problem of how to create MAP for characters to display;
If you gonna using row scan another use column scan I think you don't use the same characters MAP nor the same circuit;can you please help me to think on this??
see the circuit I want to use,if someone has codes it is better that he/she share with me .
How to know whether you scan rows or whether you scan columns ;for my case for example one column has to provide current to many diodes;will I scan column,s how will I proceed iin coding??
Thanks.
