Dear all,
I am trying to implement a StreamDevice driver for a Leybold Graphix Three vacuum gauge controller.
With the help of Pete Owens I got the basics running very quickly, but now I am stuck with parsing string outputs from the controller.
The message structure for receiving data is:
[ACK] Value CRC [EOT]
which is implemented in my protocol file as follows:
get_string {
out SI "\$1;\$2 %<notsum>" ;
in ACK "%s%0.1<notsum>" ;
}
When I receive a string response I get the following error:
Input "" does not match format "%0.1<notsum>"
and the CRC is not recognized but added to the string output.
Is it in general possible to parse this message format without knowing the response string length in advance?
Best
Daniel
