I need help....i have a code for scrolling "A" in the led matrix (code attached below) using mikroC and i simulate it using proteus. Proteus simulation has correct output but when i try to load it on my circuit, letter "A" is not complete(video is also attached below for reference).

schematic diagram is also attached.

pls tell me what to do...i tried manipulating the code but it didnt work
thank you

Seems likely that you have made some mistake in your physical circuit/ wiring, since you say the simulation works & hence code is OK.
I suggest you carefully review your connections as well.... you have not posted the actual circuit, so it's a little difficult to point out any sources of error.
 




i tried reviewing and reviewing my connections...and i didnt find any wrong connections..

i'll try to paint my actual connections...tell me if its right
thank you for replying to my thread..
 

Can you upload your Proteus project or its video ?

In that program ,where is the code for scanning ?
How do you sent data serially ?

Thank you sir for replying to my thread
The first loop is for the lighting of the LEDs and third loop is for the scrolling.

i will upload the proteus file.

im with adelair

the proteus file has different result with the video...since t has correct output..but n actual circuit..the first line for "A" is lacking..
