Read the datasheet. If you are a student you are going to have to learn to read the datasheet every time. To answer your question, yes you will need two. One as TX and one as RX. These units can RX and TX. Using these units will make your life easy as they handle all of the encoding/decoding.XBee 1mW Chip Antenna CAN THIS MODULE RECEIVE ALSO?? I MEAN THT I HAV TO BUY TWO MODULES ONE AS TRANMITTER AND OTHR AS THE RECIVER??
ACTUALLY ITS DEFICULT TO GO FOR THESES MODULES COZ I ALREADY BOUGHT TLP/RLP MODULES.
PLS REPLY TO MY THIS QUESTION
i hav to transmit 8bit data, can i use ht 640 nd ht 648 encodr/decodr? Aftr using these chips would i gt my data clrly with out any garbage?????
how wil i be able to trnsmit nd receive 8 bit data using 4 data lines of Ht12e pair?↲
push acc
swap a
anl a,#0Fh
mov p1,a
clr TE
setb TE
pop acc
anl a,#0Fh
mov p1,a
clr TE
setb TE
.i hav to transmit 8bit data can i use ht 640 nd ht 648 encodr/decodr? Aftr using these chips would i gt my data clrly with out any garbage?
yes. poll VT then read the byte from the port.use polling method to chk the VT pin if it goes high thn i would call receive function and after displaying the control would be returned to polling position
onething more for example if i change the transmitter ,wt would be best for me? the one u told me or any othr ,as u know tht i hav to transmit temperature and fire status (fire sensed or no fire etc) 8 times in a minute.
