Determine the multiplexed input keys

Syntax: Easy n

Easy Format provides friendly access to keyboard scanning arrangement. Typical keyboard scanning schematic are preset in hardware supported with standard keyboard scanning routines written in assembly language. Standard scanning arrangement in Easy Format are:

Setup	Configuration	Trigger Names
Easy 8	2x4	TG1;TG2.....TG8
Easy 12	3x4	TG1;TG2.......TG12
Easy 16	4x4	TG1;TG2.........TG16
Easy 20	4x5	TG1;TG2...........TG20
Easy 24	4x6	TG1;TG2.............TG24
Easy 32	4x8	TG1;TG2...............TG32
Easy 48	6x8	TG1;TG2.................TG48
Easy 64	8x8	TG1;TG2...................TG64

In the Easy Format program, it is required to specify one line statement for the I/O pins to support the scanning function by a simple schematic. Trigger names (i.e. TG1; TG2; ... TGn) are then assigned to each scanning switch location. This schematic is a standard circuit and cannot be changed by user.

Declare Voice/melody file

Syntax : voice file / compression method
melody file
tone file

If any audio file is used in the application, it is required to declare ahead. The compression methods of voice files have different option, such as PCM8 and AD4.

Example:

Voice1.wav/pcm8        ; #0 voice files declaration
Voice2.pcm/ad4           ; #1
melody1.mid                 ; #2

Define Input States

Syntax:
     INPUT STATES
     ;                       TRn                ....
    statename:     [rising edge path][/falling edge path] ....

The general format to specify the I/O states is presented by a table with the above format. When the TRn detects a rising edge or falling edge signal, the path name of the specified path will be executed. User can define the statename and the path label. The symbol "/" denotes the falling edge path which is an optional existence.

Define Output States

Syntax:
     OUTPUT STATES
     ;                       OUTn            ....
     statename:      OutputMode ....

The possible output mode are listed as follows:

OutputMode	Description
X	Set OUTn to input with pull high resistor
H	Set the output pins to logic high
L	Set the output pins to logic low
P+	Send a (+) pulse train to output pins
P-	Send a (-) pulse train to output pins
SP+	Send a plus single pulse to output pins
SP-	Send a minus pulse to output pins

Define the Paths

Syntax:
PATHS
pathname: path command ......

The PATH section defines the executing instructions of the application. User can define multiple pathname which is consisted of sequence of path commands. Each pathname is initiated by the Input state table when a trigger is detected. The path command can also instruct to change of next input/output state. All the commands are summarized as follows:

Path command	Description
Input statename	To active input state.
Output statename	To active output state.
Pathname	To execute the specified path.
VAR=pathname	Define the variable path.
VAR	To execute the variable path.
Volume_1=n	Define the volume 1 value (n=0 .. 15).
Volume_2=n	Define the volume 2 value (n=0 .. 15).
Samplerate_1=n	Define the sample rate 1 value.
Samplerate_2=n	Define the sample rate 2 value.
Delay (n)	To delay n (min=0.1s) (n=0.1 .. 65).
TRn?H:Pathname	If TRn is logic High, then the pathname is executed.
TRn?L:Pathname	If TRn is logic Low, then the pathname is executed.
Flashrate = n	Set the output pulse rate to "n" pulses per second, where n can be assigned as 1, 2, 3, ..., 12.
FlashrateT = n	Set the output pulse rate after the melody tempo, n=1, 2, 3, ... 12.
FlashrateV = n	Set the output pulse rate after the volume, n=1, 2, 3 , ... 12.
END	Enter power down mode.
Mi = PB	Read Port B to Mi.
STOP1	Stop the sound of channel 1 playback.
STOP2	Stop the sound of channel 2 playback.
Mi = data	Set the contents of Mi to be data.
Mi = Mj	Set the contents Mi to be Mj.
Mi(bn) = 1 or 0	Set bit bn to be 1 or 0, bn=0..7.
Mi = Mj + data	Add immediate data with Mj to Mi.
Mi = Mi + Mj	Add Mi with Mj to Mi.
Mi = Mj.AND.data	AND immediate data with Mj to Mi.
Mi = Mj.OR.data	OR immediate data with Mj to Mi.
Mi = Mj.XOR.data	XOR immediate data with Mj to Mi.
Mi?data:pathname	If Mi=data then pathname is executed.
Mi?Mj:pathname	If Mi=Mj then pathname is executed.
Mi(bn)?1:pathname	If the bit bn of Mi is "1" then the pathname is executed.
Mi(bn)?0:pathname	If the bit bn of Mi is "0" then the pathname is executed.
Mi:[Path1,Path2, ... ,Pathn]	Path1 is executed when Mi=1. Path2 is executed when Mi=2. Path3 is executed when Mi=3. ... Pathn is executed when Mi=n.
Random(Mi)	Get a random code and put it to Mi.
Timert:timer_path	Initialize the timer. If time out then timer_path is executed, t=0.1 ... 65 sec.
TimerOn	Start the timer counter.
TimerOff	Stop the timer counter.
nsoundfile, n#N or #N	Play the soundfiles n times. #N is the N'th soundfile which is defined in the audio file declaration part. The starting number is 0.
[nsoundfile] or [repeat soundfile]	Play the soundfile n times or repeatly via channel 2 and simultaneously execute the next path command.
Wait	Stop executing the next path command until the channel 2 soundfile is terminated.
