This document discusses controlling a stepper motor using a microcontroller's serial port communication. It covers connecting a stepper motor, understanding step sequences, asynchronous serial communication protocols, timer settings for baud rate, and code for moving the stepper motor and implementing delays between steps.

Controlling stepper motor using serial communication with computer
- 2. Project Title: TO CONTROL STEPPER MOTOR WITH COMPUTER USING SERIAL PORT COMMUNICATION OF MICROCONTROLLER
- 5. Difference b/w Rotor & Stator of Stepper & other Motors
- 11. Serial communication uses 2 methods • Synchronous method transfers a block of data at a time. • Asynchronous method transfers a single byte at a time.
- 12. Asynchronous serial data communication • A protocol is a set of rules agreed by both the sender and receiver on • How the data is packed. • How many bits are for data. • When the data begins and ends.
- 13. Asynchronous
- 15. • RS323 • STANDARD • TTL • STANDARD
- 22. Timers of 8051 • TMOD Register
- 23. • TMOD=0x20; //use Timer 1, mode 2 • TH1=0xFA; //4800 baud rate • TR1=1; //start timer
- 25. SCON=0x50;
- 26. MOVEMENT,DELAY B/W EACH STEP OF STEPPER MOTOR void MSDelay(unsigned int); void MSDelay(unsigned int itime) { unsigned int i,j; for (i=0;i<itime;i++) for (j=0;j<1275;j++); } P2=0xCC; P2=P2<<1;
