Successive Approximation ADC

    Today in this paper we will be understanding how an successive approximation ADC works. We are learning this basic working principle because sooner we will be dealing on how to interface an analog to digital converter with AT89s52 microcontroller. And because most of analog to digital converter uses successive approximation analog to digital conversion method for conversion of analog signal to digital signal it is important to understand successive approximation method of digital conversion before interfacing an analog to digital converter with any microcontrollers.

HM-TR interfacing with AT89s52

HM-TR 434 is a wireless radio frequency module with default configuration(9600,8,N,1). In this post i am going to give a tutorial on interfacing HM-TR with AT89S52 microcontroller.But first you are encouraged to read this post UART in AT89s52 / Serial communication using AT89s52.The pin configuration of this module is shown below.
