How can I use a servo motor on the LPC2103 MCU?

Marcus Vinicius

I'm still a beginner on deep embedded systems development. I would like to know how to control a servo motor without using PWM, since I didn't actually learn anything about it on my classes and I'm not sure wether I could use it or not.

    Ok, but most servo motors use a 50 Hz (20 ms period) repetitive signal, where the pulse width nominally 1-2 ms or 500-2500 us, controls the angle of the output shaft.

    This is the poster child for a microprocessor PWM timer/generator.

    Get the LPC2103 reference manual, and review the timer/pwm section. Any teacher worth listening to should be able to demonstrate this within as couple of minutes.
