if you get:
“error: ‘MatrixNet’ does not name a type In function ‘void setup()’: In function ‘void loop()’:”
You forgot to set the:
Tools > Board > Displayduino 644
You must always remember to include the MatrixNet libraries and begin MatrixNet in the setup.
#include
MatrixNet myMatrix;
void setup()
{
myMatrix.begin();
}
void loop()

Hi – Just wondering about Arduino 0018 Support for this product. Is the software download going to be updated anytime soon?
Is the current revision compatible with 0018 if I just copy the relevant folders over into the new structure of 0018?
(Posted this in the Main Controller section too by mistake, sorry.)
Thanks
Hi!
The current version should be compatible with 0018 if you copy the relevant folders into the new structure, yes, but I haven’t tested it myself. It’s definitely on the to-do list to get 0018 working nicely – the target for that is in the next week or two.
Thanks,

I have a few different Arduino style boards now and it would be useful to use one software stack. The Arduino software is at 22 now and Displayduino is still shipping with 17c. Can you be more specific about what might need to be copied? I tried copying from Displayduino (ie {DD}) to Arduino (ie {AD}) as shown below and this didn’t seem to work even after a restart of the IDE. Can you provide a list of the folders/files you think are necessary to copy?
{DD}/hardware/cores/displayduino to
{AD}/hardware/arduino/cores/displayduino
{DD}/hardware/bootloaders/displayduino644 to
{AD}/hardware/arduino/bootloaders/displayduino644
{DD}/hardware/bootloaders/displayduino324 to
{AD}/hardware/arduino/bootloaders/displayduino324
Hi,
I found this cool web project. http://www.modk.it/
Maybe you could be integrated board and your libraries then there may even people without much knowledge of software work with mondomatrix.
Hi Luxor … good to hear from you. We actually saw ModKit at the Maker New York this year and we agree they are awesome! We are going to be working on this in the coming weeks.
HI all,
I have the servomatrix for a project using 103 servos with very specific timing instructions. Many people have suggested using PWM to control the servos because i have thousands of commands but mondomatrix does not support PWM. Will I need to use another method to control the timing of lot of servos using the servomatrix?
Thanks.
The ServoMatrix board uses a PWM signal to control up to 64 servos and you can have 8 different servos using 8 different power sources (if you need them).
Hello,
I am trying to use Max/MSP to control displayduino and LEDmatrix but cannot find a patch/messaging system that works specifically with the Displayduino. Is there anything I can do to use Max/MSP to control it?
The Displayduino uses Arduino code. Have you tried looking at the Max/MSP example for Arduino?
Example: http://www.arduino.cc/playground/Interfacing/MaxMSP
I have tried maxuino and can see how to communicate with the displayduino’s digital and analog pins but don’t know how to get max to communicate with the LEDmatrix board.
This is not something we have developed but it sounds like a great contribution – know anyone who would step up to the plate?
I am trying to individually control a matrix of 80 rgb leds with constantly changing color values (0-255) coming from a live video feed which has been downscaled to 8 by 10 pixels via Max/Msp. Any suggestions? I have the displayduino and two ledmatrix boards.
the example we have build uses Quartz Composer. We have it working well in that example – but we have only done demos with it and it would have to be cleaned up if we were to post it on the site. It is possible. If you end up in a rut let us know and we will see what we can do.
hi.
is there any chance to see the serial code you are using to communicated to the expansion boards?
I would like to connect and LED matrix directly to a computer use a usb to serial to rs 485 adapter.
Thanks,
Stephan.
Hi Stephan,
This might be hard because the chip we use has more memory and speed. We don’t really support other connections though if you get that rolling we would love to share it with others.
