Share string between Linux API and MicroBasic script was created by marcusbarnet
Is it possible to use a C application in Linux with Roboteq Linux API to send a value to a microbasic script which is already running in the controller?
I mean, I would like to have something like this pseudo-code in my script to run in my controller:
In this way, my controller do nothing if it receives a zero value and it starts processing data only when my C application send a value greater than zero.
If this is possible, what kind of instruction do I have to use to read values from C application via USB?
Thank a lot

Use the VAR to exchange numbers with script
from linux: sendcommand VAR, varnumber, varvalue
in script read with getvalue(_VAR, varnumber)
In the other direction. In script setcommand(_VAR, varnumber, varvalue)
Read from linux with getvalue VAR, varnumber
from linux: sendcommand VAR, varnumber, varvalue
in script read with getvalue(_VAR, varnumber)
In the other direction. In script setcommand(_VAR, varnumber, varvalue)
Read from linux with getvalue VAR, varnumber

Thank you a lot!
I guess getvalue() is a blocking function in microbasic, isn\'t it?
In this way, I can use it to let the script (and the controller) wait for a string from my C application.
Is it correct if I do this?
In C application:
In microbasic:
May be I\'m not understanding the difference between varnumber and varvalue.

I\'m having problems with API reference.
I found no occurences for SendCommand() function in Roboteq API: what kinf of function do I have to use if I want to send a value to a microbasic script?
