hi,

can any one help me to build a moving display using PIC 16F877 and four 5x7 led matrix in c (MikroC)

Thanking You
Soina
 

i tried to implement a ckt to scroll message as tutorial in proteus and Mikroc. i failed to obtain a output .. any one can post a working schematic with PIC16F877 and 5x7 matrix led with c code.. Thanks in advance

You have used both the Chips as 74Hs595 ???, I doubt it will work. You should have used one 74LS138 as decoder for rows
and a shift register 74LS164/74LS595 for driving column.

another thing you just mentioned clock=1, clock =0 in your C code, but I could not find which pin you are using as clock.
in your C code you should try to send each bit of the character data and send a pulse to the shift register.
and to the rows should be scanned continuously. so when a row column pair match the corresponding LED glows.

hope this helps a bit.
 

Thank u for ur response .. clock is defined for the pin PIN_B0.. i coudnt work shift register with pic. the out puts are orderless.. if u hav any schematic n code , can u post it.. i want to scroll a text from right to left using four, 5x7 led matrix with help of PIC 16F877. i know only C language( MPLAB,Mikroc)
 

i got a solution for the scrolling message with PIC6F877 and 5x7 led matrix..
nw im working to scroll message in four,5x7 matrix ,,
code is written in MPlab IDE and simulated in proteus
here im attaching my work..
thanks a lot to everyone
