8051 Microcontroller Trainer
The 8051 microcontroller trainer is designed specifically for educational, institutes and individuals who are interested in 8051 microcontroller. It includes a Microcontroller Module with I/O ports Module, DC Power Supply Module and 9 standard application modules & 2 optional student projects module.
Features:
o Standard 87C52 CPU clocked at 22.1184 MHz
o 50 I/O lines with 10 x 5 rows of 2mm brass socket & Turn-pin input/output ports
o 32k SRAM, program variables and code (24k usable for code download)
o 30k Flash ROM, non-volatile program storage and data logging
o High speed baud rates: 115200, 75600, 38400, etc. All standard baud rates are supported (except 300 baud)
o Display port, works with optional standard character-based LCDs such as 16x2 LCD display
o Eight LEDs, controlled by 8 dedicated I/O lines (not shared with the 50 I/O lines)
o Bus expansion with 4 chip select signals, for adding UARTs, A/D converters and other bus-based peripheral chips.
o EDUMON monitor program for easy code development without additional equipment.
The Main Frame
- The 8051 microcontroller board are built-in to the main frame. This will allow students to have visibility of the 8051 microcontroller board with minimum access to the board.
- 10 x 5 rows of 2mm brass socket & Turn-pin input/output ports are provided.
- DC power supplies of +5V(two each), -5V(two each), +12V(two each), -12V(two each) and GND (two each) are provided.
- The reset/restart button for the microcontroller should be easily accessible on the main trainer.
- Computer interfacing connectors of 8051 board are available.
- Input Voltage: AC 240V ; 50Hz
Accessories
o Power cord with a 13A fused mains plug at one end and a straight socket at the other.
o Relevant sets of 8051 technical data and programming manuals.
o RS-232 interfacing cable.
o Technical information, instruction manuals and circuit diagrams for the 8051 Microcontroller Trainer and Application Modules (including soft copy).
Application Modules
The set comprises 9 application modules which attached to the main frame of the 8051 microcontroller trainer unit. The application modules powered from the 8051 microcontroller trainer's built-in power supply module.
Functional details of the Application Modules :
Module 1 : 8 Bits Data Display Module
This module consists of 8 input sockets and 8 buffers driven LEDs. It is used for monitoring the status of the each output port bit of the main frame.
Module 2 : 8 Bits Switch Input Module
This module consists of 8 toggle switches and 8 buffer driven output sockets. It is used for input of data to the input port of the main frame.
Module 3 : 7 Segment Display Module
This module consists of two 7-segment displays. The display is driven by a BCD to 7-segment driver IC through 2 multiplexing transistors.
Module 4 : Digital To Analog Converter Module
This module consists of an 8-bit D/A converter IC. Its output drives an inverting op amp with variable amplification factor.
Module 5 : DC Motor Control Module
This module consists of a small DC motor, 2 relays for direction control and an amplifier circuit for feeding PWM power to the DC motor.
Module 6 : Stepper Motor Control Module
This module consists of a 4-phase unipolar stepper motor driven through a buffer IC. 4 LEDs are connected to the stepper motor terminals so that phase status can be observed (at low speed stepping only).
Module 7 : Keypad Module
This module consists of a 12 key keypad wired up in 3 x 4 matrix. It is an input device for the main frame.
Module 8 : Dot Matrix Display Module
This module consists of two 5 x 7 dot matrix LEDs. They are driven by buffers in a 10 x 7 matrix.
Module 9 : LCD Display Module
Consists of a LCD panel (2 x 16 characters). Supply + 5V DC and ground terminals
Module 10 : Trigger Sensors And Alarm Circuit Module (Student Project)
This module consists of 4 photo-coupled input devices and 2 transistors driven devices, a buzzer and a lamp.
Module 11 : Car Park System Application Module (Student Project)
This module consists of 2 sets of Infrared detectors, 2 motor driven gates, and four 7-segment displays. This module is designed for testing automatic car-park system software on a small scale.
