1. Introduction

The CompassDT1 RoboBrick is a RoboBrick that can be used to connect to a Devantech CMPS01 compass module. This compass uses two Philips KMZ10A megnetic field sensors to measure the direction accurate to 0-3599 (i.e. .01 degree accuracy.) Please note that the magnetic field inside a build can be off by 10's of degrees.

2. Programming

{To be written}

3. Hardware

The hardware consists of a circuit schematic and a printed circuit board.

3.1 Circuit Schematic

The schematic for the CompassDT1 RoboBrick is shown below:

The parts list kept in a separate file -- compassdt1.ptl.

3.2 Printed Circuit Board

The printed circuit board files are listed below:

compassdt1_back.png: The solder side layer.
compassdt1_front.png: The component side layer.
compassdt1_artwork.png: The artwork layer.
compassdt1.gbl: The RS-272X "Gerber" back (solder side) layer.
compassdt1.gtl: The RS-272X "Gerber" top (component side) layer.
compassdt1.gal: The RS-272X "Gerber" artwork layer.
compassdt1.drl: The "Excellon" NC drill file.
compassdt1.tol: The "Excellon" tool rack file.

4. Software

The CompassDT1 software is available as one of:

compassdt1.ucl: The µCL source file.
compassdt1.asm: The resulting human readable PIC assembly file.
compassdt1.lst: The resulting human readable PIC listing file.
compassdt1.hex: The resulting Intel^® Hex file that can be fed into a PIC16C505 programmer.

The CompassDT1 test software is available as one of:

compassdt1_test.ucl: The µCL source file.
compassdt1_test.asm: The resulting human readable PIC assembly file.
compassdt1_test.lst: The resulting human readable PIC listing file.
compassdt1_test.hex: The resulting Intel^® Hex file that can be fed into a PIC16F628 programmer.
