From what I know, I think they just output according to what they got as input. So the inputs have to be programmed somehow, like using a microcontroller to interface the inputs.
can this be done with the holtek series of encoders/decoders in rf communication with control inputs given by 8051
thus can i give encoder and decoder address at one of the ports-p2 from the 8051 and data to the encoder from port p0 and receive data from the decoder at port p1.also any interfacing is required b/w 8051 and encoder or can i connect them directly from the ports to the encoder address pins.
help me Plz its urgent
