A serial port interface circuit has been designed and tested for programmable control of multiple permanent magnet unipolar stepper motors to be used in a biped robot. In this work, a stepper motor control system of a biped robot having 10 degree of freedom, 5 on each leg is proposed, that will be built in-house in a economical way. The circuit con...

Context 1
... Serial port interface circuit is designed with serial connector shown in Figure 1. Once the sequence of motor steps is calculated, it is sent via serial communication from any of the PC's COM# Port (RS232) through MATLAB Program. ...
Context 2
... second part of the microcontroller code reads the data from the EEPROM and sends the pulses to the required motor in decoded direction. There is a mode change switch implemented in the circuit PIN 14 of the microcontroller (refer Figure 1) which decides the download or working code to be functional based on the position of the switch. The indicator pin PIN 15 of the microcontroller fitted with a Light Emitting Diode (LED) is used to indicate the download completion while data transfer and cycle completion in running mode. ...
