$SERIALINPUT1

Action

Specifies that serial input of the second UART must be redirected.

Syntax

$SERIALINPUT1 = label

Remarks

With the redirection of the INPUT command, you can use your own input routines.

This way you can use other devices as input devices.

Note that the INPUT statement is terminated when a RETURN code (13) is received.

By default when you use INPUT or INKEY(), the compiler will expect data from the COM2 port. When you want to use a keyboard or remote control as the input device you can write a custom routine that puts the data into register R24 once it asks for this data.

$SERIALINPUT2LCD

Action

This compiler directive will redirect all serial input to the LCD display instead of echo-ing to the serial port.

Syntax

$SERIALINPUT2LCD

Remarks

You can also write your own custom input or output driver with the $SERIALINPUT and $SERIALOUTPUT statements, but the $SERIALINPUT2LCD is handy when you use a LCD display. By adding only this directive, you can view all output form routines such as PRINT, PRINTBIN, on the LCD display.

Example

$regfile = "m48def.dat" $crystal = 4000000 $baud = 19200

Config Com1 = Dummy , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0

Config Lcdpin = Pin , Db4 = Portb.4 , Db5 = Portb.5 , Db6 = Portb.6 , Db7 = Portb.7 , E = Portc.7 , Rs = Portc.6

$serialinput2lcd Dim V As Byte

Do Cls

Input "Number " , V 'this will go to the LCD display

Loop

$SERIALOUTPUT

Action

Specifies that serial output must be redirected.

Syntax

$SERIALOUTPUT = label

With the redirection of the PRINT and other serial output related commands, you can use your own routines.

This way you can use other devices as output devices.

$SERIALOUTPUT1

Action

Specifies that serial output of the second UART must be redirected.

Syntax

$SERIALOUTPUT1 = label

$SIM

Action

Instructs the compiler to generate empty wait loops for the WAIT and WAITMS statements. This to allow faster simulation.

Syntax

$SIM

Remarks

Simulation of a WAIT statement can take a long time especially when memory view windows are opened.

The $SIM compiler directive instructs the compiler to not generate code for WAITMS and WAIT. This will of course allows faster simulation.

When your application is ready you must remark the $SIM directive or otherwise the WAIT and WAITMS statements will not work as expected.

When you forget to remove the $SIM option and you try to program a chip you will receive a warning that $SIM was used.

$SWSTACK

Action

Sets the available space for the software stack.

page -247-

© MCS Electronics, 1995-2007

Syntax

$SWSTACK = var

Remarks

Var A numeric decimal value.

While you can configure the SW Stack in Options, Compiler, Chip, it is good practice to put the value into your code. This way you do no need the cfg(configuration) file.

The $SWSTACK directive overrides the value from the IDE Options.

It is important that the $SWSTACK directive occurs in your main project file. It may not be included in an $include file as only the main file is parsed for $SWSTACK

$TIMEOUT

Action

Enable timeout on the hardware UART 0 and UART1.

Syntax

$TIMEOUT = value
