Part 2

Ok so the first entry was getting a little long, so I decided to create another.

Now is time for the Master control unit:



Master PicBasic Code here http://pastebin.com/8nNVxzn8
Found a suitable housing (plastic) so the X-Bee radio network could easily operate inside the enclosure.

Made some indicator boards so I can see where the PIC is in the program. These boards have 74LS595 shift registers and the Led's march as the code dictates. If there was an error in communications a flag is thrown and the red led is lit & the node is skipped until next round. When the data transmission completes the error bit is cleared.






Note the 120VAC outlet on the left. That is for controlling an Insteon Power line modem so I can send commands to IR transmitters and control the Mini-split units in each zone.
