Another simple (& free) alternative GUI for avrdude is AVRDUDESS (http://zakkemble.co.uk/)

That will work fine with an Eleven. I have often added a LM386 amplifier to Arduino projects. I have a couple of Elevens that form the basis of halloween decorations that play samples off SD using the Adafruit WAV Sheild. One of those I use a small practice guitar amp on the output which is somethin...

i Already have a scoreboard with controller from android apps, but this scoreboard just add the score and not for team's name , anyone can help me to add the code to insert the name team , So looking at the code all your Andriod app is currently transmitting a single character command to reset the ...

Hi, If your alphabet has a traditional order (akin to A, B, C, etc) then every symbol could be referred to by that index. If there are 30 symbols (I'm basing this entirely from wikipedia) then defining your symbols from A through ^ would allow you to do what you want, as a substitution cypher. It's ...

I recommend reading this post by @Brissieboy. His custom font is very well commented and from reading that I learned what I needed to create fonts.

All the best, Geoff

Hi, This one is entirely on me. Additional to the new firmware, there were also minor updates to our custom PCB. One important difference was relocating resistors that were on the ISP programming lines as some protection for the DMD (to stop it flickering etc) when programming. Prior version they we...

That is richly bizarre. Glad you sorted it with a workaround.

Hi

Did you resolve this? Was the video the result of one of the DMD2 example sketches without making any changes?

Hi, Is there anything significantly different in the signals created by DMD2 that would cause this? I've updated the firmware for an existing project that uses a cable between the custom PCB (ATmega386 based, essentially a Uno) and 4x DMD panels. The PCB and cable only transmit these pins: GND D13 S...

They daisy-chain by design. Every project where there is more than one DMD module in use has them connected one after the other. The Arduino connects to the last DMD in the chain. Make sure you power them with something beefy, and if you use a different power supply for your Arduino to the DMD make ...
