OPERATION CALC is a simple calculator which reads in
single digits and produces two digit results. The keypad is scanned by row and column, and
the ASCII code for the key which has been pressed is returned. This is
converted to a BCD number (subtract 30h) and the selected calculation
performed. The two digit BCD result (max 9x9=81) is
processed for display as two digits (divide by 10 for high digit). Divide results are displayed as integer
result and remainder to avoid decimal point processing. The LCD driver is included as a separate
file derived from the routine developed in the LCD demo application. |
