I hope somebody can help me....at least get me pointed in the right direction.
I have a few SLR2016 5x7 Dot Matrix LED displays to test. I would LOVE to get something set up with an Arduino to just make sure these things work. I have searched the web for days on end and searched through this Arduino forum without luck. I have found a few YouTube videos that show this exact chip with scrolling text, but no one posts the code or schematics on how they did it. What is frustrating is that other users have posted questions on requesting the code or schematics and they do not get a reply.
It is like these people do this just to show off without sharing their knowledge.
These displays have 14 pins. They are:
Pin 1 Write Pin 2 A1 Digit Select Pin 3 A0 Digit Select Pin 4 Vcc Pin 5 D0 Data Pin 6 D1 Data Pin 7 D2 Data Pin 8 D3 Data Pin 9 D4 Data Pin 10 D5 Data Pin 11 D6 Data Pin 12 Display Blank Pin 13 Clear Pin 14 GND
The displays have their own CMOS memory build in.
I don't have my Arduino kit here (hoping it will be here tomorrow), but I am hoping to get an idea where to go with this.
I see on the board that on one side of the board is marked Digital 0 through 13. Will I just jumper each of my D0 through D6 to these?
I see an A0 and A1 on the board too....will my A0 and A1 go to those?
Ground and 5v is pretty self explanatory.
That Display Blank and Clear do not have any corresponding connectors.
I found one comment on a website that said "I realized that they used the standard ASCII charset, so they are extremely easy to drive."
Ummm....no. They aren't when you have no idea what you are doing.
I have the Arduino software installed. I have the ASCII charset codes. I understand how to load code onto the Arduino.
Can anyone get me pointed in the right direction?
Thanks so much.
