Frequency

7.3.5

Frequency Generator Function
Uses output channel 0 for Timer 0 and output channel 2 for Timer 1.

Can generate a frequency between 1 and 10kHz

Waveform will have a duty cycle of 50%

7.3.6

PWM Generator Function
Uses output channel 0 and 1 for Timer 0 and output channel 2 and 3 for Timer 1. This
function allows the user to generate a waveform up to 10kHz with a user defined duty
cycle. The frequency of both outputs is the same but the duty cycle can be varied by
changing the low time for each of the channels.

Specify timebase, from 1µ second to 1second

Specify PWM period as a function of the timebase

Specify first channel low time as a function of the timebase (Chan 0 for Timer 0 or Chan 2
for Timer 1)

Specify second channel low time as a function of the timebase (Chan 1 for Timer 0 or
Chan 3 for Timer 1)

Enable/disable second channel as output

7.3.7

One-Shot Pulse Generator Function
Uses output channel 0 and 1 for Timer 0 and output channel 2 and 3 for Timer 1. This
function allows the user to generate a single or multiple pulse waveform with a specified
pulse width. The pulse can be repeated either by a software command trigger or by a
rising edge on the first channel. The user can specify a Pre-Delay which will execute
once the trigger has been received and/or a Post-Delay which will be used to ignore any
triggers until the delay has expired.

Specify timebase, from 1µ second to 1second

Specify trigger for pulse generation: Software command, hardware rising edge or
hardware falling edge

Specify number of pulses to generate before stopping

Specify output pulse polarity as positive or negative

Count of number of pulses generated

Specify length of pulse as a function of the timebase

Specify length of pulse Pre-Delay as a function of the timebase

Specify length of pulse Post-Delay as a function of the timebase
