 This example shows the support of PWM for servo-motor control.
-Servo-motor position is set by reading on ADC input 0.
+Servo-motor position is set according to characters received on serial line,
+between '0' and '9', with 20° steps.
 
 The PWM signal is output on port 0 pin 23 (LPC_TIMER_32B1_M0_PIO_0_23), using
 32 bits timer 1, match channel 0.
