pic16f877 projects

hi everyone .
i am beginner in pic programming. I got a project which involes the use of PIC16f877 . i need to display numbers on whiteboard (its not a board, its like a seven segment display , but not a board).
i need to build the hardware as well as the soft ware. the project is Braille to number. so i need to convert the braille input to the display. there are six switches for input.

however, i don't really know how to write the source code using Assembly language.
the connection between numder display (whiteboard (kingbright TC20-11GWA)) and pic and elctronics.

can someone give some guidance?( pls provide schematic diagram if possible)

does anyone have any exampler report or assighnment, that would be great help too.
thanks!

Hi ayeshasana.

I think you could take some good idea from this good page. The task is very same.

Hello ayeshasana

I couldn't sleep last night, so I made a quick sketch for your project. Its a could be the starting point.

The main concept comes from here:
https://hobby_elec.piclist.com/e_pic6_23.htm
At the middle of page there is an animation about the principle of the working.

For my sketch:
We put the first column's pattern through rc0-rc6
then we select the 1st coulum by rd0. Wait for a short time.
Next we put the 2nd coulmn's pattern through rc0-rc6 and select the 2nd column by rd1. And so on.
At the other side we are watching the state of Sw1-sw6 switches.(Brile switches).
According to the Braile switches we put the appropriate patterns to the white board. Column by column enough fast for not flickering.

you are great ........ thanks alot for your sketch...... i want to do the coding in Assembley language... can you please please please help me with that ??????????? i am working on it but i am badly confused ???

Write your questions.
If you have concrete question, I try to answer it.
But it would be very complicated to start explain about assembly in general.
Make a study of 16F877 datasheet, if you haven't done.

for example:How you can configure the I/O ports to input output.
Let"s start somehow.
