144 LED Games Console Project

[mtripoli]

thanks, but I have 17years, and in school we are making SCH and PCB with tango, and I won't buy displayes, I buyed 144 LED diodes.
Can you just connect that R19 on my schematic that I uploaded, and tell me if I have connected LED diodes correctly, because I edited your schematic

Your schematic looks a little odd for the displays. As shown it looks like the leds being used are offset in different directions so if the they are physically pushed together there would be rows and columns not lit. The resistor you are so worried about (R19) originates from one of the "d-pad" switches. These switches are pulled low and are active high as drawn in the schematic I did. I believe Art changed the code to reflect that. In his original code he had it as drawn with two pulled high and two pulled low for no reason whatsoever. Why you have another low value (120 ohm) resistor tied here I can't imagine. It looks to me like you simply copied the schematic wrong. Look at the original schematic in the RAR file I posted. This is not a difficult project. You've admitted "editing" the schematic; don't make changes to a circuit if you don't understand the circuit in the first place and then demand that others fix it for you or explain it to you.
