42 RabbitLink (EG2110)
E.2 Variables Commands
The RabbitLink serial console has the ability to handle SSI (Server Side Includes) vari-
ables. These variables are stored in an xmem buffer. This means that the memory will lose
the variables when power is cycled, although the references to the variables will still exist.
Remember that any HTML file that includes SSI tags must have the file extension
.shtml.
createv <varname> <vartype> <format> <value> [strlen]
This command creates a variable and stores it in the flash file system on the RabbitLink. The
variable can be referenced in HTML files using SSI; e.g. <!--#echo var="var1"-->).
varname The name of the variable.
vartype Type of the variable (int8, int16, int32, float32, or string)
format The printf-style format specifier (such as %d) for outputting the
variable
value The value to assign to the variable
strlen Maximum length of the string for variables of type string.
EXAMPLES
createv var1 float32 "%.2f" 3.14
createv var2 string "%s" "This is a test." 50
getv <varname>
This command gets the value of the specified variable. The value is printed using the format
specifier given in the createv command.
varname The variable whose value is requested.
putv <varname> <value>
This command assigns the specified value to the specified variable.
varname The variable whose value is being changed.
value The new value for the variable.
