 		 #81253 - RE: analog to digital controllers
Responding to: ???'s previous message
respected sir
we are doing a project for control and automation of airconditioning plant. there are totally 7 parameters to be controlled. we are using 8051 microcontroller with anolog to digital converter and digital to analog converter. which converters can be used for 7 parallel inputs and outputs.

should we use 8255 programmable peripheral interface also.

Informative!
What is the cuestion?
