Re: DOT MATRIX

you, can use mc AT89cxx ,pic16f877 ,etc


for 40 columns and 8 rows

assume there is large data to display


scan loop2.........

scan loop1..........scan this upto your requirment = 20-30 times (not exact)

take first byte and place on row
then select first column line
small delay

clear the row data
take 2nd byte and place on row
then select 2nd column line
small delay

so on upto 40th column

scan loop1..............................................

after this increment the data pointer by 1

scan loop2..............................................

ok

but , it is just example , brightness of display also depends scanning speed .

enjoy
