i need help constructing the keytable to include in my program. This 'keytable' has to be included at the start of the assembly language program and is similar to the LCD initialisation sequence i.e.
initseq: DB 38h, 38h,........,0FFH
Each of the keys has to represents two letters i.e. key 1 = 'ab' key2 = 'cd' i know nothing about this key table which needs to be included in the program and am having difficulty researching the code to perform the key presses.
