Command |
SETUP(PWM) |
|
|
|
|
Description |
Setup the protocol for the
Pulse width modulation |
|
|
|
|
Syntax/Parameters |
setup(pwm){...} |
|
|
|
|
Options |
active=123; //to enable the required combination of
PWM's use 1,2,3 and N=none eg 1, 12, 13, 23, 3
OR
active1=Y/N; active2=Y/N; active3=Y/N;
pol1=H; //polarity = High or Low on first
phase of PWM1
pol2=H; //polarity = High or Low on first
phase of PWM2
pol3=H;
cycle1="200"; //cycle time in microseconds of PWM1.
Range 160Hz to 1MHz
cycle2 = "300"; //cycle time in microseconds of PWM2.
Range 160Hz to 1MHz
cycle3 = "300"; //cycle time in microseconds of PWM3.
Range 160Hz to 1MHz
duty1=
"44"; //value
of first phase as a percentage for PWM1 = 1-99
duty2=
"56"; //value
of first phase as a percentage for PWM2 = 1-99
duty3=
"56"; //value of first phase as
a percentage for PWM3 = 1-99
delay=
"50"; //delay
between first phase of PWM1 and first phase of PWM2 in microseconds
PWM parameters cycle1, duty1, cycle2, duty2, cycle2, duty3
now accept float parameters giving greater PWM resolution. - v49.37 |
