Good day all, I am working on a big project with several arduino nano's tied together with I2c.
(and so far it seems to be going well given enough time, but I am still a beginner)
This is the project: I have 1 arduino running as a master on a I2c network, by using buttons it will send the number 1,2,3 etc on the network to the other arduinos. (and showing the function on a display)
Some arduino's will transfer the number to a motor, relais or waveshield or to a LPD8806 led strip.
Now I have got the LPD8806 part to work with the I2C, by sending 1,2 or 3 to this arduino it will execute the light pattern associated with it.
But Iam having trouble keeping the pattern in a loop, it will now run for 1 or 2 times and then I have to send the number again. And the pattern cannot be interrupted.
The funny thing is that the hole LPD8806 script came from a wheelchare project by Cranium.
(many thanks go to him, I've got another LPD8806 project running completly on his script)
Original script: http://arduino.cc/forum/index.php/topic,79839.15.html
The orginal script is using a button who can interrupted the current running loop at all times, but I am not sure how to replace the button control with the I2c control and keep the hole thing running the same.
I will be grateful for any tips or help...
Here is the changed script up till now: (orginal can be found on the link above)
