\subsubsection{Oxford Instruments ITC4 Temperature Controllers}
|
|
SINQ makes heavy use of Oxford Instruments ITC4 temperature controllers. In
|
|
order to support them the following software components had to be defined in
|
|
addition to the basic environmet controller interfaces:
|
|
\begin{itemize}
|
|
\item ITC4driver, naturally.
|
|
\item A ITC4-controller object as derivation of environment controller. ITC4
|
|
's allow you to select a sensor which you read as your standard sensor and a
|
|
sensor which is used for automatic control. The ITC4 controller object adds
|
|
just that additional functionality to the statndard environment controller.
|
|
\end{itemize}
|
|
The additional data, the selection of sensors, will be kept in the driver.
|
|
This serves also an example for implementing inheritance without C++.
|
|
|
|
The driver interface:
|
|
@d itcd @{
|
|
pEVDriver CreateITC4Driver(int argc, char *argv[]);
|
|
int ConfigITC4(pEVDriver self);
|
|
int SetSensorITC4(pEVDriver self, int iSensor);
|
|
int SetControlITC4(pEVDriver self, int iSensor);
|
|
int GetSensorITC4(pEVDriver self);
|
|
int GetControlITC4(pEVDriver self);
|
|
int SetDivisorITC4(pEVDriver self, float iSensor);
|
|
float GetDivisorITC4(pEVDriver self);
|
|
int SetMultITC4(pEVDriver self, float iSensor);
|
|
float GetMultITC4(pEVDriver self);
|
|
int SetTMOITC4(pEVDriver self, int iSensor);
|
|
int GetTMOITC4(pEVDriver self);
|
|
|
|
@}
|
|
|
|
The ConfigITC4 is special. It has to be called to commit changes to the
|
|
driver read and control parameters.
|
|
|
|
The ITC4 object interface:
|
|
@d itco @{
|
|
int ITC4Wrapper(SConnection *pCon, SicsInterp *pSics, void *pData,
|
|
int argc, char *argv[]);
|
|
int ITC4SetPar(pEVControl self, char *name, float fNew,
|
|
SConnection *pCon);
|
|
int ITC4GetPar(pEVControl self, char *name, float *fVal);
|
|
int ITCList(pEVControl self, SConnection *pCon);
|
|
@}
|
|
|
|
The functions defined are: new parameter handling functions, with just
|
|
support for the two extra parameters added and a new Wrapper function for
|
|
SICS. The meaning of all these functions, their parameters and return values
|
|
are identical to those defined for an environment controller. Additionally,
|
|
the standard environment controller functions will work as described. The
|
|
functions described above are just needed to implement the extra parameters.
|
|
|
|
@o itc4.h @{
|
|
/*-------------------------------------------------------------------------

Support for Oxford Instruments ITC4 Temperature controllers for SICS.
|
|
The meaning and working of the functions defined is as desribed for a
|
|
general environment controller.
