adafruit / piccolo Goto Github PK

Hi, I'd like to use this example with my rgb led table but I'm struggling with upscaling the project to reflect the equalizer to a 10x10 matrix. Can you give me a hint on how to extend the arrays: noise, eq, col8data, col9data?

I couldn't find the License for the arduino-sketch.

Hello !

I'm a beginner in arduino and I'm not very familiar with some operations. I saw in the code expressions with a constant before a variable (256L or 0L) and I was wondering what it was doing. I tried to look for informations on the internet but it was hard to formulate (I tried searches like "number before variable in c") and I didn't find anything relevant.

Could you help me?
