Pic Program Analog Read for Threshold and Digital Output

Here is my second program using one of the Pic 16F684's Analog to Digital Converters. I needed a voltage window detector for the simple lamp circuit in the crickets. More or less it is neccesary to send a Digital high if a voltage is greater than voltage 1, but less than voltage 2. Here using Vcc and Ground as reference, I've read a value from the PickIt1's on board potentionmeter, and sent a digital signal based on its position in relation to the window. Once again, not sure this is the best way to go about the process.

Pic Program to Control Charlieplexed LED Array

Due to some issues in the Digital Crickets for DGL, I've been doing some PIC programming using a borrowed PickIt1, Pic 16F684 and High-Tech C compiler. This has been an interesting journey. In the future I'm thinking I might go the AVR direction because there seems to be more documentation out there. Though PIC does have a good, internationally attended forum that reponds quickly. As always the community is where to go for trouble shooting. I thought I'd post my very first sucessful program. It's a short program to cycle through a the PickIt1's Tri-state Charlieplex.

Sonifying LIS30DL

I’m really excited about building the Evening Song piece for my space. It’s actually going to be pretty easy I think. This is a lo-fi cap of some work in that direction. Here I am controlling 3 midi channels with the X, Y, and Z vectors of the LIS30DL accelerometer (Cheapest one Sparkfun carries). I use Processing’s Serial library to interpret the sensor data and TheMidiBus (MIDI library) to convert the sensor data into midi notes. This is good progress to me due to the fact that I know very little about MIDI. I use Mac’s built in IAC Bus drivers to make the data available to other programs.
