Connection of RF module to PIC16f877A

Share
Above is connection of Rf to PIC microcontrollers via HD12E ic So in left side of ic A0-A7 these are address pins, you can ground all or put in any configuration according to your address. Right side of this ic contains data pins transmission enable pin oscillator pin and data out pin.
Between oscillator pin you have to connect 1.1Mohm resistance which acts as a RC oscillator AD8-AD11 are data pins which you have to connect with your PIC data pins. and last is te bar pin which you can connect to any  pic Pin it is used for TRansmission Enable.

Rest you can download all the data sheet and circuit connection from this link

note:- Connection for the RF receiver is same but you have to use HD12D IC
i hope it may help you all...
