Sunday. Picked up the paper as usual at 7:05 AM. I noticed the $10 off Lowes coupon from Libbie expires today so I'll go down and pick up another roll of aluminum foil for the crawl space. Late last night I changed the port for Rembrandt and can now access the http server on port 9320. Next step is to compile a "hello world" program before I compile my own temperature reading program.
After lunch went to Lowes and picked up the roll of foil. Back home I collected pine straw off the driveway and picked up tree limbs in the backyard as well as pruned the roses and weeded.
After a quick shower I settled down and compiled a hello world program using Cygwin and GCC on my PC, Mazeppa. Downloaded Hello World to the Rembrandt and executed it OK.
Next step is to write a One Wire program derived from lots of examples on the web. I'm going to either use a serial port or the TWI port on the AVR32.
Studied some one wire interfacing techniques using 3 volts which is a problem. The Uart will provide the timing but will have to buy some GasFet transistors from Digikey or Mouser. Cost is $.14 each which is more than acceptable but will have to buy 100. because of quantity pricing. Started writing the interface program using Digitemp as a guide. I also need to look at OWFS to see how they did serial port I/O. Fell asleep downstairs watching IFC, went to bed at midnight.
