New Module - Inside DeMux to Encode Switch Data Sleep Mode Sleep Light Indicator Old Receive Module No On/Off Switch PicAxe Program Port Resets Inside Four Outputs Outputs Hardwired to Toy New Module - Improvements Power Light Indicator Power Switch CMOS External PicAxe Programmer Problems Encountered Conflicting Voltages PicAxe Chip: 5V XBee Chip: 3.3V Solution Emailed MaxStream on maximum voltages Problems Encountered X-CTU Software Would not recognize XBee Chips Could not program XBee Chips Serial Cable connection unreliable Solution Reinstalled X-CTU and Serial cable drivers Bought USB to Serial Cable Used different computer Problems Encountered ZigBee Communication Get ZigBee Chips to talk to each other Solution Trial and Error Change settings on X-CTU program Problems Encountered ExpressPCB Software Save file corrupted Trouble finding components in library Solution Modified backup file Problems Encountered PicAxe Pinouts Confusion on PicAxe pins Output number vs. Pin number Solution Reference PicAxe PDF manuals Problems Encountered Hardware Bugs Incorrect wiring Floating pins Weak batteries Software Bugs Mislabeled pins Stuck in unending loops Approach to Solving Bugs Protoboard Break circuit into modules Test each component Use data sheets Use LEDs for debugging Coding Break functions down Test each module seperately Refer to PicAxe manuals Implement pauses to check program Outstanding Problems None! Suggestions Project Specific Make own board Save on cost Make smaller modules Smaller PicAxe, One ZigBee, FET Use smaller batteries Save space Make whole circuit run off 3.0V vs. 3.3V Reduce current consumption through XBee Sleep ZigBee – Final Status Instruction Manual: Done Transmitter Module: Done Receiver Module: Done Modules working together: Done Plug and Play usability: Done Sleep Mode: Done Project: Success
