This circuit demonstrates the principle and operation of collecting data from ADC and sending it to PC via serial communication using microcontroller AT89C The circuit is divided into three parts: This circuit can be used as an intermediate in many applications.

ADC which is an 8-bit resolution ADC has only one input channel connected to variable resistance preset to give the analog input. In place of preset, analog input from a sensor can also be used. AT89C51 is an 8-bit microcontroller and belongs to Atmel’s family. These digital signals are used for further processing by the digital processors. Various sensors like temperature, pressure, force etc This high-density System-in-Package SiP integrates controller, power switches, and support components.


Interfacing ADC0804 with Serial port (RS232) using 8051 micocontroller (AT89C51)

Skip to main content. The output pins of the ADC are connected to port P1 of the microcontroller. Write Xdc0804 pin 3 is connected to P2.

Read RD pin 2 is connected to P2. The IC Max is used to ensure compatibility between controller and serial port Refer serial port interfacing through controller.

Interfacing ADC with Microcontroller

The program continuously monitors the output of ADC and transmits it to the serial port. The input to the ADC is supplied through a preset. When the value of preset changes, the corresponding output changes and is displayed on the hyper-terminal.

Hyper Terminal shows character corresponding to the ASCII values Refer serial port interfacing through controller for hyper-terminal settings. This Code is only visible to Registered users.
