PIC Serial Interface

This circuit is an interface between your radio control transmitter and your computer comm port. It connects between the transmitter trainer jack and a computer comm port, 9 pin. The interface reads the PPM data from your transmitter and converts the pulse widths to numbers. It then sends those numbers to the computer via a 9pin comm port at 19200 baud. This interface is generally intended for use with FMS.
Interface Features
- Full 8 bit range used for PPM width, except FF which is the SYNC.
- Data sent every PPM frame, approximately 50 times a second.
- High speed baud rate, 19200.
- Test communication mode.
- When no PPM signal present interface sends "Interface OK No PPM"
- Using Hyperterminal you can test for proper communication to your computer comm port.
- Auto Powerdown after 2 minutes without PPM signal.
- Auto Powerup when PPM signal returns.
- Works with either Futaba, Hitec, JR. Just change transmitter connector.
- Very easy to setup.
- Compact size.
The PIC code described here does not work with Airtronics but I do have a working hex code for an interface that works with all brands including Airtronics. If interested you can a request it by email.
