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 should be powered from the 8051 microcontroller trainer unit otherwise an additional power supply unit should be provided.
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.
