Hi

Have a look here http://www.picbasic.co.uk/forum/showthread.php?t=11871

I played with Sure modules way back - late 2000s and used 2 modules to make a nice large clock and where the digits change by scrolling upwards with the new one scrolling in from the bottom.

It took a while to design the dot matrix data for the characters and for doing the vertical scroll.

But it all started from the above link.

I see the chip is EOL. But modules are still available on Ebay though not the Sure ones I used, but as the current Ebay modules use the same chip and control lines, the code should work.

I will have a look for my old early codes (not well documented!) and perhaps post one, it will be a few days !!
