My led matrices (EC40-11GWB) came in a few days ago. After reading the data sheet: http://shop.emscdn.com/im/LED/EC40-11GWB.pdf I was unable to find out which pins on the matrix controlled which leds. Can someone tell me how to count the pins on the matrix so I can match it up to the data sheet. Ill post a picture after I find my camera.
After skimming the MAX6953 data sheet a few times I thought of something. Do I need resistors between each screen and the chip? Does any body have a schematic. If not could some one maybe make one(Please). Also if some one told me what was needed I could make it and post it for everyone.
Thanks, wow my searching skills are sure lacking today. Ill keep looking thanks for everyone's help. Just one last question does anyone have a good beginner (or advanced) circuit book that they could recommend?
Is there anything cheaper? Maybe it could only control one display would be ok. I cant really imagine spending $25 on a chip that ill probably solder wrong and it does not really look like it would go in a breadboard.
This would be great, perfect size and reasonable price. My only question is how many pins would I need to control this matrix and could I use some kind of a chip to decrease the pins needed without much work.
