RaDeKL_SetInterval

Set the automatic detection interval for continuous detection mode. When the radar is in continuous mode,

a new detection is performed each time this interval expires. The default setting is INTERVAL_50_MS.

NOTE: There are currently 5 distinct interval settings (see table below), but the actual range of

permissible settings should be obtained by calling RaDeKL_GetDeviceInfo and using interval_min

and interval_max, as these might change with future versions of the radar unit.

Format:

ULONG RaDeKL_SetInterval (RaDeKL_HANDLE handle, BYTE interval);

Parameters:

handle RaDeKL_HANDLE as returned by a call to RaDeKL_OpenRadar.

interval A BYTE indicating the requested interval. Permissible interval values are:

Symbolic Constant Duration Value

INTERVAL_1_SEC 1 second 0

INTERVAL_500_MSEC 500 milliseconds 1

INTERVAL_250_MSEC 250 milliseconds 2

INTERVAL_100_MSEC 100 milliseconds 3

INTERVAL_50_MSEC (default) 50 milliseconds 4

Return Value:

RADEKL_OK (0) if successful, a non-zero status otherwise. See RaDeKL_GetStatusText for codes.

Example:

Set the continuous detection interval to 100 milliseconds.

ULONG status;

RaDeKL_HANDLE handle;

// Assume we have an open radar with a valid handle

status = RaDeKL_SetInterval (handle, INTERVAL_100_MS);

// Check status . . .
