actually i have to solve an problem for my versity project.the project is to display LED.if any body help me about this i'll be very helpfull all the project description given bellow
a) The pulse generator and 8 bit IO by using switches for input and the LED display for output.
The switches may be read repeatedly (“polling”) but this is too inefficient and we shall use
the pulse generator buttons to get an interrupt. When the left button is pressed you shall read
the switches. The input shall then be echoed to the LED display.
b) The pulse generator may register which of three events that was the interrupt reason. The
left button, the right button and the frequency pulse. You shall use the frequency interrupts to
make a simple clock and the right button pressed to get the clock displayed on the LED display.
