Using the matrix / membrane keypad develop an integer calculator to add. subtract and multiply up to three numbers. The results are to be displayed on the LEDs. You will need to carefully consider how to display results that are greater than 255 or negative (Hint: use an additional key to switch between the upper and lower 8-bits.). To increase the complexity, you can include division. When performing a division, the quotient and remainder can be displayed separately. Given that the ATmega32A has limited division support a reminder that division is repeated subtraction until a value of less than zero is obtained. Need both c code you can only use #include <avr/io.h>!!!!!!!!!!!!!!!!!!!!!!!!!!! keypad: 1|2|3|A 4|5|6|B 71819|C *|0|#|D Using the matrix / membrane keypad develop an integer calculator to add. subtract and multiply up to three numbers.
