hello sir,
as a matter of fact it is our be project! we need 2 make a 19inch rack which will hold different 96 pin male connectors. for eg. we can either have a dac or adc or digital i/o which will be connected 2 the 96 pin male connector on rack and these divices can be selected using dip switches.a saperate 96 pin connected 2 the c8051f040. so sir can u pls send the design so that max divices can be included in rack. also we need 12-bit adc, dac design( any adc,dac, digital i/o) pls.......

first you need to find out which ADC you are planning to use, because only after that.. design can be made. According to your need you can find out an ADC. try visiting www.national.com

hello sir,
for now we r leaving the rack business..will configure it later..first we r planning 2 design an external dac ckt using quad dac7744..now we r planning 2 use the port po of c8051f040..as the main addr line and we will be able 2 interface 2^8 devices with its help. as dac7744 is 16-bit quad..we will have 2 use p1 & p2 ports of the c8051f040 for data i/o. port p3 is internally connected to the internal 12-bit adc so we r not bothering it..also we have 2 design the quad dac ckt , it pcb layout and interface it with port p1-p2 such that we use it as 12 bit..also we need 2 give chip select and various other selection i/p needed 2 be given 2 the external ic of dac7744.. so pls help ..if u didn't get anything clear the pls ask 4 verification..(any data sheet or ic details reqd..)

and what i was saying was.. make the circuit and show me.. if any mistake i will tell you. that is what project help is about..
i hope getting me.. see you have planned something to do as per your previous post... so start it.. what are you waiting for..
make the circuit... then take the screenshot or directly attach the file.. and show me.. i will take a look and tell you what is right and what is wrong. you can check the forum, people work and take help.. to see whether they are doing right or wrong.. that is what i expect from everyone and that is how you are going to learn on your own
