I've looked everywhere for help but the answers were too vague so this is my last resort.
I bought an adafruit Trinket with 5V logic and I bought a led matrix kit on amazon that uses a MAX7219 IC.
After soldering the kit together, I see that there are 5 pins on this module
1st pin: VCC
2nd pin: GND
3rd pin: DIN
4th pin: CS
5th: CLK
I have no idea what pins 3, 4, and 5 are used for. So I was wondering if I can get a little help here so that I can use my LED matrix. What I want to do with this for starters is just have all LED turn on and turn off.
Please help!
Thank you for reading this :)

Re: Need help on using Trinket to control LED matrix
Have you contacted the vendor for documentation or support?

No, but the only reason why is because I've seen other people use the same 8x8 LED matrix with their Arduinos.
Although the Trinket isn't an arduino, I was hoping I could still use it for the matrix

Well, you can start at the Arduino Playground:
http://playground.arduino.cc/Main/LEDMatrix
I'm not familiar with the chip or any of those libraries, but they might work on the trinket.
