I use multiple 8*8's LED dot matrix, with 4 8*8 can form a 16*16 matrix, then the line between the two 16*16 is how to connect?
Choose the line of code can be a total of two 16*16 connected to the corresponding, similarly...
Line access. The column requires nothing more than a separate grounding, 16*N dot matrix display, oh....
The connection between the two does not need it, and then connect the driver circuit with the microcontroller, after receiving the LED to see how you control the program...
