How to interface Servo Motor with 8051 Microcontroller (AT89C51)

[hina rubab]

Can anyone please tell me What crystal is used in this project….i am littlebit confused about this…i am using 11.0592MHz but i couldnot get desired results…please help me…

Hi,

 

Can you please post schematic and code?

Yup i picked schematic and code from this link

for controlling servo motor you can use crystal of 4 MHz, 8 MHz or 12 MHz or any other. it does not matter. because your delay calculation for generating pulse depends upon this crystal frequency value. that you can simply substitute and get the desire value. with 11.059 MHz crystal you might not be getting exact delay that is required. this crystal is used only when micro controller communicates with PC. so just change crystal.
