Quick Reference
Methods/Functions
Name Parameters Return Description and Notes
high pin none Set output pin to high
Automatically sets pin to output
low pin none Set output pin to low
Automatically sets pin to output
toggle pin none Reverse state of output
Automatically sets pin to output
inp pin Byte (ASCII 0 or 1) Read input pin
Automatically sets pin to input
a2d channel word Read analog channel
Returns 0 to 1023
a2dconf justify, clk2x, reference None Set 1 to left justify result
Set reference = 0 for supply rails, 1 for analog 3 used as +
reference, or 4 for analog 2 as – reference and analog 3 as +
reference (note: clk2 parameter not used)
pwm channel, duty_cycle,
duration/freq none Output pulse width modulation
If channel = -1, use hardware PWM with specified
frequency; otherwise use software PWM for specified
duration
Automatically makes pin an output
count pin, duration word Counts pulses on specified pin for duration (in mS or 2mS
for Pi)
Automatically makes pin an input
rctime pin, state word Measures time pin stays in state (2uS resolution; 4uS for Pi)
Automatically makes pin an input
pulsein pin, state word Measures pulse (2uS resolution; 4uS for Pi)
Automatically makes pin an input
pulseout pin, duration none Creates pulse on output pin for specified duration (2uS
resolution; 4uS for Pi)
Automatically makes pin an output
freq pin, frequency, duration none Make pin an output and synthesize sine wave
Frequency in Hz (2 Hz for Pi), duration in milliseconds (2
mS units for Pi)
setcounter prescale, mode none Set prescaler (1, 2, 4 or 8) and timer/counter mode
resetall none none Reset GP3
repeat count none Repeat next command
readbyte none byte Read bytes from repeated command
readword none word Read word from repeated command
Notes:
Pin numbers are from 0 to 7
A/D channels are from 0-4
