Entering user module code
Enter the C code.
Refer to
supported I/O and SMU commands.
To enter the C code, enter the new C code into the module-code entry area.
For the TwoTonesTwice user module, enter the code listed below. The code deliberately contains a
missing ; error to illustrate a KULT debug capability.
/* Beeps four times at two alternating user-settable frequencies. */
/* Makes use of Windows Beep (frequency, duration) function. */
/* Frequency of beep is long integer, in units of Hz. */
/* Duration of beep is long integer, in units of milliseconds. */
Beep(Freq1, 500);
Beep(Freq2, 500);
Beep(Freq1, 500);
Beep(Freq2, 500);
Sleep(500)

Entering parameters
To enter the required parameters for the code:
1. Click the Parameters tab.
2. Click the Add button at the right side of the parameters tab area.
3. Under Parameter Name, enter Freq1.
4. Click the Data Type cell and select long under Data Type, as shown here. This is the C data
type.
For an output parameter, only the following data types are acceptable: pointers (char*, float*,
double*, and so on) and arrays (I_ARRAY_T, F_ARRAY_T, or D_ARRAY_T).
5. For this user module, the I/O entry of Input is correct. If the Data Type is pointer or array, you
could choose Input or Output.
