Monday night (Nov 10) I’ll be going over the I2C protocol and how to make it work for you. I2C is used in all sorts of sensors these days, and understanding how to make the AVR’s speak it is useful stuff!
I’ll bring in some I2C external memory chips, a temperature sensor, and a 3-axis accelerometer. There’ll also surely be steaming hot, AVR-to-AVR, master-slave action. After a little bit of lecture and some code demo, we’ll see how many of them we can get working…
7pm. The Space.
In honor of Columbus Day, the AVR class took a night off from “formal” instruction and messed around with noisemakers. Specifically, using analog-to-digital conversion techniques to control the pitch of a square wave run through a small speaker. Hilarity ensued. (Follow along with us at the AVR Microcontroller Class Wiki Page.)
