I bought a sure electronics green LED display, its basically 4 8x8 LED matrices on a circuit board. It seems to have its own built in controller and has only 8 pins. Has anyone used these before? how would i go about interfacing this with the arduino. here is the data sheet.
The LED drive chip is a HT1632
There was extensive discussion and code posted here: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1225239439 (It's a different display, but uses the same controller chip.)
Thank you so much! i should have searched the forum first!
I got a couple of them and managed to modify the code from the other board demo to drive it ok. The dimming problem is just as bad as the larger display it seems so really they are not a viable solution in their current form.
