To solve this we thought the problem might have been the resistance not being exactly what was calculated.
At first there was a 7 degree difference between the 68HC11 and all the other readings. Timer and Interrupt Source code.
UTexas Homepage for Microcontroller courses. UNM howto on microcontrollers. W, X, Y, and Z. While all of the reading were not exactly as read by either the thermometer or the water bath sensor, this could be fine-tuned by either the resistors used or through code changes. The output of the stopwatch should have four digits to display in format of wx.
To allow for consistent results we also included a mercury thermometer.

Driving 7 segment display source code http: Also included in this objective was the task of designing software to do the following: The program consists of three parts.
If so then the tenths digit is incremented and the hundredth digit is reset to zero. SMU Microprocessors help pages http: The procedure to load the file into the microcontroller is the following: Driving a 7 segment dsiplay http: I took readings from the lowest point we could reach and read which was 2 degrees C and then took reading at 5 68hx11 intervals.
