Reading
Sec 7 to Sec 7.1.4 is the A/D Math we discussed in class. The reset of Chp 7 is specific to the 68HC11 microcontroller's A/D. Chp 8 is about connecting to the A/D and is interesting reading.
 HW #1 - Due Oct 2 at start of class (see instructions for details).

Using a honeywell 24PCDFB6G pressure sensor and pneumatic setup supplied by the instructor, do the following
  1. Use a relay driver to turn on and off the compressor
  2. Create a LabVIEW VI to run the compressor while the pressure switch (Nason SM-2b-115R/443) is at it's NC possition. Also display the signal from the Honeywell 24PCDFB6G
  3. Presurize the system and get the data needed to generate a calibration curve for the (0-30 psi)
  4. Using an Op-Amp circuit, convert the current signal from the honeywell pressure sensor so that the circuit outputs a 0-5v signal for 0-30 psi
  5. Modify the VI to maintain a set pressure at the pressure sensor (using a "Control" to set this pressure).

Demonstrate to the instructor. Submit final VI and excel spreadsheet with calibration / gain calculation(s) via online submission.

Peer Evaluations will be conducted at start of Lab Nov 1.
