Calculator using the keypad of the HC12 - rock...@gmail.com - Oct 1 9:27:09 2007
HI everyone,
Im wondering if anyone could help me with programing a basic calculator using assembler language.The calculator is only meant to store the number shown when the '*' button is pressed and then another number is put in and when '#' is pressed both numbers are to be added.I can get the Keypad press to show the numbers on the display but cannot store the actual number shown.It always shows either 'a' or 'b' when the '*' or '#' buttons are pressed and then freezes.
Any help will be greatly appreciated.
