Re: DMD Notes

Geoff, I've tried using your spreadsheet to create a 16px high font like Brissieboy's but it doesn't seem to work. Is there any reason I wouldn't be able to use your spreadsheet to do a 16px high font? Do I need to alter the value total size of the font? Here's the font code. cheers, Trav #include <...

Re: Serial input and the interrupt timer in DMD library

I left it around lunch time to move onto some other work and I decided to have another look at it before I left the office. I added a 5 ms delay after my while Serial.available line and it is now working perfectly. Now I just have to tidy the code up, and next step is to see if I can combine it all ...

Serial input and the interrupt timer in DMD library

Is it possible that the interrupt timer can cause issues with an incoming serial string on the arduino? Here's my scenario. I have an arduino (A1) that takes a HEX string input over SoftwareSerial, pulls a couple of relevant bytes out of it, and converts them to ASCII in a character array. I want it...

Re: DMD Notes

That's the original DMD Library. (Not the modified one for flipped panels).

Re: DMD Notes

I'm putting together a 3x3 sign at the moment and will need to display numbers from 0 - 999. Thus I'm looking to create a number font that is 48px high and obviously no wider than 32px (a bit less to allow for gap between). How hard is it to modify this spreadsheet to allow for this?

more than 6 panels with Chinese controller

Has anyone looked at using one of the Chinese matrix controller to drive more than 6 panels, and feed realtime serial text to it from an arduino board? Wondering if this is even possible, and if that would be a simple solution to trying to drive larger arrays.
