I'll
gladly answer questions regarding software that I've
written, but I
cannot help with homework, class assignments, projects
and unrelated 68HC11 programming questions. Thanks.
LCDTemper
LCDTemper
is a
fairly simple 68HC11 program that reads a single DS18S20
temperature sensor (for the now
obsolete DS1820) and displays its
temperature (in degrees C) on a 16x1 LCD display. The temperature, in
ASCII, is also available at the serial port. LCDTemper runs on an MIT
miniboard.
LCDTemper demonstrates:
I used this version of the LCD FAQ to help me write the LCD code and with the hardware interfacing to my surplus 16x1 display.
The pictures below show my Miniboard in a small project box.
This version of the program is relatively simple; it reads a single device and displays the temperature to the nearest 0.5C.
LCDTemper8 can read up to eight devices (using the SearchROM and MatchROM commands) and calculates and displays the DS18x20 extended temperature (good to 0.1C).
