Digital to Analog Converter 14. I2C Interface 15. RJ-45/RS-485/RS-232 interface 16. Servo Motor Control 17. DC Motor Control 18. Temperature Control. 2. Write a brief description of each module available in MC-8600. PSU PSU provides FOUR different voltages i.e. +12V, -12V, +5V, -5V for external use. Programming Port Programming port is used to serve as a mean to program the controller. It consists of a DB9 and Jumper Connector J1. RS-232 cable is connected to DB-9 for the transfer of data from PC. LED Array LED Array have 8 LED array i.e. L0-L7 and to control it a Jumper Connector J2 is provided. Interrupt Source There are two interrupt sources included in this module. One is active low INT0 and other is active high INT1. DIP Switch 8 DIP switches can be used to input the data through jumper connector J3 to controller. Key PAD Key PAD is used to demonstrate the multiplexing technique. It contains alphanumeric keys i.e. A-Z,0-9, arrow keys, delete and back space and can be used to input the controller by jumper connector J4. 7 Segment Display 7-Segment display also have concept of multiplexing. It has four 7-segments display with two jumper connectors J9 for data and J10 for control signals. 16x2 Character LCD A 16x2 character LCD is provided to display text data. It displays the character data (A-Z, 09).J11 port is used to connect with microcontroller. Contrasts of LCD can be controlled by pot provided. 128x64 Graphic LCD A monochrome graphical LCD is provided to display both character and graphic data. It provides 128x64 pixel area for display. It has two connectors. J14 is data port, while J15 is control port. Analog to Digital Converter Atmel AVR/Microchip 16 series controller comes with built-in 8-channel, 10-bit Analog to Digital Converter. There are 8 channels CH0-Ch7 for digital input. Digital to Analog Converter It converts 8-bit digital data from controller to analog signal available at O/P. Offset can be controlled by tuning the pot provided. Servo Motor Servo motor is commercially used in many applications. They are commonly found in robotics, UAVs. A PWM signal is sent by controller to SERVO motor driver that controls the speed and step size of rotation (0o to 180o). DC Motor DC motor demonstrates the concept of feedback speed control system. A disk with a slot is attached to a DC motor. This slot upon rotation cuts the IR sensor, which sends the pulse train to the controller. The frequency of pulse train gives the rpm. Speed of DC motor is controlled by H-Bridge which provides 4-quadrant motor operation. PWM signal is generated from controller to set the desired speed and direction of rotation. J8 connector is used to connect to the micro controller. Temperature Control Temperature control is used to study the discrete/digital PID control system. A 5W resistor is used to model a heater. A temperature sensor is attached to the heater that sends temperature data to the microcontroller/PID controller. It then turns on/off the fan to set the temperature in the desired range.
