Worked on the temperature probe in the morning checking all the timings of read and write of ones and zeros to see where the problem may be. It seems to be reading FF for the temperature as confirmed on the scope. After changing the timings I'm now getting AD. Found that I need to set the output to a strong one (active) or else the bus droops to 1.5 volts with just the pullup after commanding a conversion. In the afternoon I took all the shutters off over the porch. I stretched a ladder across the porch roof to give me some balance. After this Libbie and I went to Lowes and then the greenhouse and nailed boards on the bottom of the plastic over the cool cells. Got home and Libbie fixed a nice dinner of flounder stuffed with crab and Brocolli. Made some more calls in the evening to get convention committees signed up.
