ER-UoB-484a Elizabeth Rweikiza added 'Questions:
I have designed a timer device(displaying 60 leds) using a PIC16F84, 8 latches
74LS373, and a demultiplexer 74Ls138.
I'm using the De-multiplexer 74ls138, connecting pins A0,A1,A2 & E1 to the
PIC pins RA1-RA3 to be able to select a particular latch (LE) I'm using 8
latches for displaying the 60 leds. Pin RA0 is connected to a push button.
Pins RB0-RB7 are connected to the input pins of the latch 74ls373 (hold &
display) and the output to the led through a 270 ohms resistor.
My question is after initialising the PIC, what instructions can I write in
order to select a particular latch,(using the 74ls138) so that it can light
the leds at an interval of 1 second?
