COMPASS / DF RS232 INTERFACE
PARTS LIST
This parts list is presently INCOMPLETE, and probably has errors.... Eventually, it will include ONLY those items required for the serial RS232 interface WITH the compass interface... if you intend to build the digital readout as well, you will have to compare this parts list with the one provided in the section titled "DIGITAL READOUT"

If you intend to build the compass / DF version, program the PIC chip with the source code in filename : DOPPLER2.asm

If you intend to build the "compass only" version, use the PIC source code in filename : COMPASS1.asm
