Sorry,a long time not update,but my Arabic language Led matrix driver board is going.pls wait a moment.
character mode,just need send Arabic char,not dot matrix data.so easy!
Good job,But why you used so much PCB?
I think if you used like this PCB an module,That' better and easy.

CD4094 same as 74HC595,
About display refresh :
step1.Choose firt row,and shift first row data to 4094/595,and then lock and enable output,after enable out put must delay some time;
step2.Choose No.2 row and just like step1
.......
if finish all rows,return step 1,
First,Do you know the matrix display how to work?operating principle is very important.

Yes,I not fond any nice codes too,thank you share.but if know it's how to work,and see the datasheet,timing,it's easy to drive,right?I think principle is important than code.
Good job!Now,i driver one 32x256RGB LED matrix display.but i not use PIC MCU and TLC5940.however,i think you are doing very nice project!if you can drive more area,and add communication,PC message editer software,it's will be perfect!
Usually,the matrix display is used to show message.Advertisement,signal...Maybe just to learn is possible.
But i really want to know where you want to use?Can you talking about it?
