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....
8051(philips)
wich one?
your post also does not make it clear what your question is
Erik
we want a C program to transfer data from one 8051 to another using their port 2's... above we have mentioned two 13 digit code...they are RFID tag codes.... i want send dese....
my work is ... i read a rfid tag using rfid reader...it takes the code.. (as i have only two tags i will represent there tag codes using some digits example 1 or 0 ) ... 8051 will check which code is read by the reader and will transfer d related number ( 1 or 0) through its port 2 to another 8051's port 2... here the second 8051 reads the number n cross checks which code it is related to and will ask the transmitter zigee to transmit this to another receiver zigbee...
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?
Yes: it's your work!
You do seem to be making things excessively complicated for yourself, though!
Surely, this could easily be done all on one 8051?!
Or is this just an exercise in parallel interfacing - not a practical solution to a real-world problem?
we want a C program ... my work is ...
i need serial comm... n ya...nxp 8051...
