Input Ports

IN_1 = Input Port 1 (Same as IN_L - Left)
IN_2 = Input Port 2 (Same as IN_M - Middle)
IN_3 = Input Port 3 (Same as IN_R - Right)
SensorType(IN_2, IN_LIGHT); //Sets Light Sensor in PORT 2

menu

SMODE_PERCENT = Percent mode
SMODE_CELCIUS = Celcius mode
SMODE_FAHRENHEIT = Fahrenheit mode
SMODE_ANGLE = Angle mode
SensorMode(IN_1, SMODE_RAW); //Sets Sensor in Input Port 1 to RAW MODE

menu

Input Types - System Commands

SensorType(i, type) = Set a sensor's type
STYPE_SWITCH = Touch sensor type
STYPE_TEMP = Temparature sensor type
STYPE_LIGHT = Light sensor type
STYPE_ANGLE = Angle sensor type
SensorType(IN_M, STYPE_LIGHT); //Sets a sensor in Input Port 2 as a LIGHT TYPE

menu

Input Configuration

Sensor(i, config) = Sets a sensor with a specific configuration
IN_CFG(type,mode) = Customized Configuration
IN_SWITCH = Touch config
IN_LIGHT = Light config
IN_ANGLE = Angle config
IN_PULSE = Pulse config
IN_EDGE = Edge config
Sensor(IN_1, IN_SWITCH); //Makes a sensor in Input Port 1 with a Touch configuration
Sensor(IN_L, IN_CFG(STYPE_LIGHT, SMODE_RAW)) // Sets a Light sensor in port 1 with Raw

menu

Output Ports

OUT_A = Output Port 1
OUT_B = Output Port 2
OUT_C = Output Port 3
Fwd(OUT_A, 1); //Tells the motor in Output Port A to go forward at speed 1

menu

Output Modes - System Commands

OUT_ON = Tells the output to turn On
OUT_OFF = Tells the output to turn Off
OUT_FLOAT = Tells the output to slowly turn Off (Floating)

menu

Output Directions - System Commands

OUT_FWD = Sets output to go forward
OUT_FLIP = Sets output to reverse direction
OUT_REV = Sets output to go reverse

menu

Full Speed

OUT_FULL = Full speed!!!
On(OUT_B, OUT_FULL); //Sets the motor in Output Port B to go full speed

menu

Output Functions

Fwd(o, p) = Sets the motor go forward and speed
Rev(o, p) = Sets the motor go reverse and speed
Off(o) = Turns off Motor
Float(o) = Slowly turns off Motor
OutputMode(o, m) = Sets the output mode
OutputDir(o, d) = Sets the output direction
OutputPower(o, p) = Sets the output power
Fwd(OUT_A+OUT_C, 4); //Sets the motors in port A and C to go forward at half speed
Fwd(OUT_A, 4); //Sets the motor in port A to go forward at half speed
OutputPower(OUT_C, 3); //Sets the motor in port C to 3rd Power
Off(OUT_A); //Turns off motor in port A

menu

General

Timer(n) = RCX timer
Random(n) = Starts a random timer, then proceeds with the program
Input(n) = Reads the value of the sensor
InputType(n) = Set Input type for sensor
InputMode(n) = Set Input mode for sensor
On(OUT_B, 8);
Random(50); //Randomly turns off motor in output port B at 1 to 5 seconds
Off(OUT_B);

menu

RCX Specific

Program() = Starts a program in a Program Slot
InputRaw(n) = Reads the input value in Raw mode
InputBool(n) = Reads the input value in Boolean mode
Watch() = Return value of the system clock
Message() = Return value of the last IR msg received
Program(2); //Starts program in Slot 2 of the RCX's memory

menu

Misc. 

Wait(c) = Tells the RCX to wait c seconds (1/10th of a second) then proceeds with the program
PlaySound(x) = RCX plays one of the system sounds [sounds]
PlayNote(f, d) = RCX plays a note by specifiying frequency and duration (1/10th of a second)
Sleep(v) = Tells program to halt for v seconds (1/10th of a second)
Display(v) = Choose which display the RCX will bring up in its LCD
SendMessage(v) = Send another RCX a number through IR
ClearMessage() = Clear Message
Wait(20); //Program waits for 2 seconds
PlaySound(3); //Program then plays system sound 3

menu

Data Logging 

SetDatalog(v) = Set the datalog size
Datalog(v) = Add a point to the datalog
UploadDatalog(s, n) = Upload datalog

menu

Controlling IR Mode 

IR_LO 0  = Sets IR range to short-range
IR_HI 1 = Sets IR range to long-range
IR_Mode(m) = Set range

menu

Notes

[sounds] Systems sounds (1-5) are numbered:

• PlaySound(1); = two short beeps
• PlaySound(2); = a slow downward arpeggio
• PlaySound(3); = a slow upward arpeggio
• PlaySound(4); = a low buzz
• PlaySound(5); = a fast upward arpeggio
