MOGlabs MWM, Manual, Page: 67 / 96

C. Programming
The
MWM
is controlled via simple text commands of the form:
DISPLAY,LINE,0,0,"Hello"
Each command begins with a text key; only the first three letters are re-
quired but the full command can be used. Some commands will have a
sub-command, and/or parameters including integers, floating-point num-
bers, and text strings. Each command will return a requested value, or a
default “OK”.
These commands can be sent to the device via
TCP/IP
(for example, using
telnet
) or
USB
. A full list of commands is provided in Appendix D.
Watchdog timer
The
MWM
has a watchdog timer that resets the device if any internal
function or operation fails to complete within approximately 5 seconds.
Thus if your application fails to receive an expected response then it can
attempt to re-establish a connection after that time.
C.1
python
example
A simple program involves opening the communications channel, config-
uring the imaging sensor, optimising the exposure time, and then either
acquiring the spectrum or the calculated wavelength. An example, writ-
ten in
python
, is outlined below. Further examples will be provided for
matlab
and
LabVIEW
.
