MicroTrac Controller v17.10/Code

Goals

• Establish serial communication over xbee radio
• Transmit commands from the "remote controller" box to "onboard controller" box.
• Attempt to run identical arduino control software on both boxes.
  • Will run in onboard mode if jumper set between defined pins.
• When in onboard mode, transmit GPS location.
• Boxes will ping each other and will shut down if connection lost.
• Store radio information in EEPROM. Update on startup.
  • Create a program to define the EEPROM
• Operate relay switches when "HAND" switch is on

Terms, Pins and Variables

Each Solenoid and corresponding relay switch will be defined by a single alphabet letter.

A - Left Track Forward

B - Left Track Backward

C - Right Track Forward

D - Right Track Backward

E - Arms Up

F - Arms Down

G - Bucket Up

H - Bucket Down

AT Commands

ATIDXXXX - set radio network ID

Code Theory

When a switch is thrown, its letter followed by a 1 or 0 will be transmitted over serial.

example: "E1" will engage the solenoid to raise the arms. "E0" will turn off the solenoid and will stop raising the arms.

While "F1" will lower the arms and "F0" will stop lowering the arms.
