First cut of MPR121

[schamp]

Jeff,

Here's the first cut of the library. My hardware is this thing from SeeedStudio: http://garden.seeedstudio.com/Twig_-_I2C_Touch_Sensor_v0.93b. It appears that channels 8-11 mirror channels 0-3 and aren't working themselves. E.g., a touch on channel 0 also results in what appears to be a touch on channel 8, likewise for 1 and 9, 2 and 10, and 3 and 11. Channels 8-11 appear inoperative when I hook touch elements up to them directly. I'm not sure what's going on here, it may be a HW problem. Anyway, channels 1-4 work, which is all I need at the moment. I hope this is a decent starting place for what you had in mind.

That's excellent! Thanks for doing this; it's a great start, and the filename conventions and function names look good. I'll see if I can finish up the remaining bits after I finish the MPU-6050. Your name will always be first in the list of authors on this one. :-)

My reference hardware is the MPR121 breakout from SparkFun, so I'll see if I can get it to work with all 12 channels with that one. We'll see.

Hey Jeff,

I'm also doing some work with an SSD1308-based OLED display controller. I like your framework, so I think I'm gonna use it. You can add that to the "coming soon" list in the README if you want.

Sounds great! I'm glad you like the approach. I'll add it to the README file for the next time I push some changes to the MPU-6050 (which should be soon) and update the Arduino Forum post. Thanks!
