  1. BLDC MOTOR SPEED CONTROL USING EMBEDDED PROCESSOR PROJECT BY K. JEBASTIN S. RAMESH D.REUBEN DEVASIGAMANI M. SATHISH KUMAR

  2. INTRODUCTION • In this project, we are going to control the speed of the DC motor using Embedded processor.

  3. HARDWARE USED • LPC-2138 microcontroller, • ARM processor, • Driver circuit for motor, • DC motor.

  4. SOFTWARE USED • Embedded “C” language programming. • KEIL micro vision 3 for ARM programming.

  6. FEATURES OF MICROCONTROLLER • n 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package. • n 8/16/32 kB of on-chip static RAM and 64/512 kB of on-chip Flash program memory. • 128 bit wide interface/accelerator enables high speed 60 MHz operation. • n In-System/In-Application Programming (ISP/IAP) via on-chip boot-loader software. • Single Flash sector or full chip erase in 400 ms and programming of 256 bytes in 1 ms. • n EmbeddedICE® RT and Embedded Trace interfaces offer real-time debugging with the • on-chip Real Monitor™ software and high speed tracing of instruction execution. • n One (LPC2131/2132) or two (LPC2138) 8 channel 10-bit A/D converters provides a total of up to 16 analog inputs, with conversion times as low as 2.44 ms per channel. • n Single 10-bit D/A converter provides variable analog output. (LPC2132/2138 only) • n Two 32-bit timers/counters (with four capture and four compare channels each), PWM • n Real-time clock equipped with independent power and clock supply permitting • extremely low power consumption in power-save mode. • n Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s),

  7. n Up to 47.5 V tolerant general purpose I/O pins in tiny LQFP64 package. • n Up to nine edge or level sensitive external interrupt pins available. • n 60 MHz maximum CPU clock available from programmable on-chip PLL with settling time of 100 ms. • n On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz. • n Power saving modes include Idle and Power-down. • n Individual enable/disable of peripheral functions as well as peripheral clock scaling down for additional power optimization. • n Processor wake-up from Power-down mode via external interrupt. • u CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads.
