I'm thinking of getting this to work without an external master.
To do that, we need to stop waiting for data to be sent by I2C and act as the master after the first Colorduino shows it on the display.
I would like you to create a code to control the display with Colorduino alone, or give me a hint for creating it.
If you give me a hint, I might be able to write the code.

Best regards

I would like to know a simple fix.
Thank you very much for your time.

Hello Wilson
How should the code be written in two Colorduinos?
In DisplayMaster, I write, leaving it like this: const uint16_t NO_OF_MODULES = 2;
In ChromaduinoSlave, I write, leaving it like this: #define WIRE_DEVICE_ADDRESS 0x06.
After this procedure, I join the two Colorduinos, leaving the Master to the right of the Slave and turn the Master on 5v and GND. But, it doesn't show any scrolling text on the screen. What am I doing wrong?
Thanks

What does this code do? I would like to use 2 or 3 Colorduino for scrolling text; Thank you

I've uploaded master code to master Arduino Uno, slave code to Colorduino (Colorduino demo works like a charm), but the master does nothing (changing delay value inside loop in master's code has no effect).

I've connected Colorduino SCL to A4 pin of Arduino Uno (master). Colorduino SDA to A5 pin of Uno (master). GND to GND.

Am I missing something here? Code looks good, I must have gotten something wrong with wiring it up.

Is this schematic also relevant for Uno? https://hackster.imgix.net/uploads/attachments/238281/p036VjisJZuDMSAGmUTB.png (omitting every element besides Nano and LED matrix here)

I have tried many libraries to control this, sometimes changing their content. But I didn't know how to control this.
I would appreciate it if you could tell me how I can control it.

I am using ArduinoIDE ver2.0.1.
Please let me know if you need any information.
I hope you can help me.
