PROGRAM IN C LANGUAGE to transfer data from 8051(philips) port 2 to 8051(philips) port 2...data is two different 13 digit codes which will be represented by a single digit .. EXAMPLE :: if the two codes are 42006B1B0032 and 42006B1B9AA8 ... then the first one is represented by "1" and the second one is represented as "0".... we need to transfer the codes from one 8051 to another.... depending on wat code has been read in the RFID reader , the respective values 1 or 0 have to be transmitted from one 8051 to another....
Actually, Philips don't make any 8051s at all - they spun-off that business to NXP a few years ago.
Now, NXP don't seem too interested in making 8051s any more: www.8052.com/.../181200
But is that relevant?
Does the assignment intend you to use specific features of the NXP (formerly Philips) chips? Would it be better to make the interface workable on any 8051-based chip?
Why use a parallel interface? Why not serial?
