hi
i have a semester project
to make an 8951 based card
whihc takes in 3 analog inputs..speed ,temperature and pressure ..with diff ranges for each
the input can beselected by the user by pressing switches or
all three r displayed
on 7 segment displays with a gap of 3 seconds....first of all i do not know how to configure the timer for a 3 second delay
secondly the 8951 also gives the voltage output to a d to a converter and also to the serial port of a pc...i have all of ths figured out
the prob here is that
im having a prb with the pins of the 8951..they r not enough for the application

i was wondering if some one can suggest how to make an address bus with 2 ports or something so that i can put the A/D and D/A on the same port
or some other way ...except PPI
i do not want to use that as already the project cost is coming out to be too much to afford
also i need a program of 7 segment display interfacing with 8951
if there r similar projects on the net
i would like to take a loo at them
ive searched and searched but havent ome up with satisfactory stuff
so any help will be apreciated
...as in guidelines
or other similar projects to look at
thankx in advance

ps i need some stuff fast ive only got this month to finish this...not to mention all my other prjects for the semester
