DEBUG
Usage: DEBUG on|off

This command enables or disables debug messaging.
When enabled, you will receive extra information via IM about operations on your SiB™.  Disabled by default.

EN
Usage: EN

This statement breaks a FOR loop.
Use this statement to exit a FOR loop before the loop reaches it's exit condition.
See FOR for more information.

FN
Usage: FN name|function [parameters...]

This command allows you to create and manage functions.
Functions are blocks of code that can be called inside of a program.  
The following commands are possible:
FN LIST
FN PRINT
FN DEL
To learn more, enter HELP FN function
To create a new function, enter FN followed by the function name, and, on new lines, the code for the function, in a single IM.
For example:
FN myFunction
[code]
will create a new function called myFunction and that function will contain the code [code].

FN LIST
Usage: FN LIST

This command lists all currently configured functions.

FN PRINT
Usage: FN PRINT function_name

This command outputs the program code stored for the given function.

FN DEL
Usage: FN DEL function_name

This function deletes the specified function.  
FN DEL * will delete all stored functions.
Neither of these commands provide a confirmation prompt prior to deletion; functions are immediately deleted and the operation cannot be undone.

FOR
Usage:

 FOR var start end increment
 ...
 NEXT
Creates a loop with a counter and incrementer.
This function creates a FOR loop, allowing you to repeat a step multiple times or increment a variable.
Example:
FOR myVar 1000 0 -100
IM Step myVar
RD button 35
IF button=1
 EN
EI
NEXT
The above program will loop and run the block with a value of 1000, then 900, then 800, up to and including 0.  The block will send a message with the current step value, then check the status of GPIO 35.  IF GPIO 35 is high, the loop is ended early with EN.  Otherwise, it continues until its end.
PLEASE NOTE that FOR cannot be used within a FN (function); only within a PROG (program).
See also: NEXT, EN

HALT
Usage: HALT

Shuts down a SID as though it had reached the end of a SiB™ (button-mode) program. 
See also: RESET

IF
Usage: 

 IF variable =|>|>=|<|<=|!= value
 [code]
 ELSE
 [code]
 EI
This function executes code conditionally, depending on a given variable's value.
A variable can be any string used in functions that output to variables; for example:
TEMP temp_var
IF temp_var > 30
IM The temperature is over 30, it's temp_var C
EI
The above code reads the current temperature value, stores it in a variable named temp_var 
and executes the code only if temp_var is greater than 30.

INIT
Usage: INIT variable=value

This function initializes a variable to the given value if the variable does not already exists.
This function should always be used at the beginning of a program (after PREW for pre-wifi programs, which must be the first line).
If a variable with the given name already exists, it's value will not be modified.
See also: SET

LOOP
Usage: LOOP

This function should only be used in a PROG or FUNCTION block.
Outside of a program, this function resets the current running program back to the first line, even if the running program is paused.
This function, when execute, loops back to the beginning of a program.  It can be used to create long-running SID-mode programs.

NEXT
Usage: NEXT

This statement marks the end of a FOR loop.
See FOR for more information.

NOSAVE
Usage: NOSAVE

This function disables the state saving of the SiB.
This function stops any future save operations on the SiB until the next power cycle (SL or HALT).  There are many reasons this function might be used.  The SiB saves it's state on each program line execution, and each variable change.  These operations can add hundreds of milliseconds to a running program, and may be undesirable in a program where the state is not needed (i.e., in a SiB program that resets on each power cycle).  Likewise, this reduces overall battery use.

NOTIFS
Usage: NOTIFS ON|OFF

Enables and disables polling for new commands.
This function enables or disables the polling for commands via IM.
This function should only be used in a program.  The state of NOTIFS is not preserved after a power reset.
This function allows you to disable remote polling when performing time-critical operations such as IO reads and writes. This function
garantees that the SiB™ will not perform any other task during the execution of the code while NOTIFS is OFF.
This function should be used safely:
NOTIFS OFF
[code...]
NOTIFS ON

PAUSE
Usage: PAUSE

Pauses the execution of the current running program or function.
When Pause is issued, the SiB™ stays powered on and awaits further instruction. The current line of execution is stored so the program can be resumed.
See also: STOP, RUN, RESUME

PRE
Usage: PRE command

Example: PRE temp mytemp
This will execute a command on the next SiB™ reset, while the WIFI is connecting.  It is useful to queue commands to run while the SiB™ is still cool.
See also: PREW, POST

PREW
Usage: PREW [command]

This will execute a command on the next SiB™ reset, prior to WIFI starting.  This is useful when accessing GPIO's on the ADC2.
It is also useful to execute entire programs without starting the WiFi component, preserving battery.
PREW can be used to queue a single [command] at the next startup, or it can be used to instruct the SiB™ to skip WiFi at startup in a program.
To use PREW in a program, PREW MUST BE the first line of the program.
In a PREW program, the command POST can be used to start WiFi.
Example:
PROG myprog
PREW
TEMP mytemp
IF mytemp<0
  POST
  IM The temperature is below freezing
EI
SL 1m
LOOP
This program will measure the temperature but keep WiFi off and power use at a minimum until the temperature reaches below 0 Celcius.
At that point, the POST command initiates WiFi.
See also: PRE, POST

POST
Usage: POST

Instructs the SiB™ to connect to WiFi when used in a PREW program.  See PREW for more details.
See also: PRE, PREW

PROG
Usage: PROG name|function [parameters]

This function allows you to create or manage programs.
To manage programs, you can execute the following:
PROG LIST
PROG DEL
PROG PRINT
PROG LOAD
To learn more, enter HELP PROG function.
To create a new program in SiB™ mode, you must name your program according to a click sequence, where
S = a short click, and L = a long click.
For example, to create a program that executes after two short clicks, enter the following:
PROG SS
[code...]
In SID mode, you can give any name to your program other than those keywords 'LIST','DEL','PRINT','LOAD', for example:
PROG daily reminder
[code...]
When a program is created, if the SiB™ is not in 'STOPPED' or 'PAUSED' mode, the program executes immediately.

PROG LIST
Usage: PROG LIST

Lists all stored programs.

PROG DEL
Usage: PROG DEL name|*

Deletes the specified program by name, or all programs if an asterisk * is specified.  This function provides no warning or confirmation 
prompt and immediately deletes the specified program(s), with no option to undo. Use this function with care!

PROG PRINT
Usage: PROG PRINT [name]

Outputs the program code for the named program, or, if no program is specified, for the current running program.

PROG LOAD
Usage: PROG LOAD name

Loads the program specified.
If the SiB™ is not in STOPPED or PAUSED mode, the program will execute immediately.

RESET
Usage: RESET

This function resets the SiB™.
See also: HALT

RESUME
Usage: RESUME

This function resumes a paused program.
See also: PAUSE, STOP, RUN

RUN
Usage: RUN [name]

Runs a program.
If [name] is specified, loads and runs the named program. Otherwise, this will run the current program in-memory.
If a program is in-memory and is in PAUSED mode, the program will be reset before running.
See also: PAUSE, RESUME, STOP

RUNEX
Usage: RUNEX [name]

Runs a program in exclusive mode.
If [name] is specified, loads and runs the named program.  This function operates exactly as the RUN function, 
but runs any program in Exclusive mode.  In Exclusive mode, commands issued via IM will be stored and will execute only when the program
finishes.  A STOP command can exit exclusive mode.

RUNFN
Usage: RUNFN name

Runs a function.
Runs the named function.
See also: FN

SET
Usage: SET variable=equation

Allows the execution of mathematical equations in running programs.
Example:
INIT a=10
SET b=a*20
IM a b
This program will send an IM containing the message: 10 200
See also: INIT

STATUS
Usage: STATUS [extend]

Echos back to SiMP™ the current status of the SiB™.
Specify EXTEND to receive more information. 

STOP
Usage: STOP

Stops the running function, program or sleep.
This function will stop the execution of any program or function.  It also exits from exclusive mode, and clears any queued items that were received but not executed.
See also: RUN, PAUSE, RESUME

WAKE
Usage: WAKE ssid time

Remains in deep sleep with short WiFi scans and wakes if a specific SSID is found.
This function will go to deep sleep and sleep for the specified time.  The SiB™ will then wake and scan for nearby Access Points.
If the specified SSID is seen, the SiB™ will wake and the program code will continue to execute.
If the specified SSID is not seen, the SiB™ will go back to sleep for the given time, and try again.
The time is specified in milliseconds, however the following suffixes are permitted: s = seconds, m = minutes, h = hours
Waking the SiB™ via button press overrides the WAKE command.
