how to "shift" a data into led matrix display ?

[CuriousOne]

Yes I will have to read data from EEPROM, since this is just short demo and I need a lot of data, speaking in pixels, it will be 200*5*7, quite much for solely PIC to handle.

Here's the sample video how it works:



But have no idea how to handle these parasitic lights, if I increase DRO variable, then these half lit segments go away, but then flicker is noticeable.

Checked in details, these parasitic lit segments are on even with larger DRO values. Tried to disable internal pull-up resistors - no change. Even tried to interlace update, do a 1,3,5,7,2,4,6 row sequence - no difference.

Solved, just added this to each line draw end routine:

c1=0
c2=0
c3=0
c4=0
c5=0
