Fix setting ScopeInfo property

[tstibor]

Setting Scopeinfo property with previous settings: min, max, step, val:

ScopeInfoNP[FocalLength].fill("FOCAL_LENGTH", "Focal Length (mm)", "%.2f", 10, 10000, 100, 0); ScopeInfoNP[Aperture].fill("APERTURE", "Aperture (mm)", "%.2f", 10, 3000, 100, 0);

resulted in error:

Error: Invalid range for Aperture (mm) (APERTURE). Valid range is from 10 to 3000. Requested value is 0 [DEBUG] Configuration successfully saved for SCOPE_INFO. Error: Invalid range for Focal Length (mm) (FOCAL_LENGTH). Valid range is from 10 to 10000. Requested value is 0 [DEBUG] Configuration successfully saved for SCOPE_INFO.

because at least one property value is 0 by default however, min values are set to 10mm, so the value cannot be set via the property settings. In addition the step size is decreased to 1mm and enum values are in uppercase letters. Moreover, the state of the property is IPS_OK only when the update is successful, otherwise IPS_ALERT.

is there a reason for this change? any other drivers using these enums?

It is used also in guide_simulator.cpp and ccd_simulator.cpp. Checking other parts of the code, it seems to be conform to use capital letter enums definitions. So far all

enum {
 CAPITAL_LETTERS
 ...
 ...
}

have this capital letter pattern. E.g:

enum
        {
            CCD_CAN_BIN        = 1 << 0, /*!< Does the CCD support binning?  */
            CCD_CAN_SUBFRAME   = 1 << 1, /*!< Does the CCD support setting ROI?  */
            CCD_CAN_ABORT      = 1 << 2, /*!< Can the CCD exposure be aborted?  */
            CCD_HAS_GUIDE_HEAD = 1 << 3, /*!< Does the CCD have a guide head?  */
            CCD_HAS_ST4_PORT   = 1 << 4, /*!< Does the CCD have an ST4 port?  */
            CCD_HAS_SHUTTER    = 1 << 5, /*!< Does the CCD have a mechanical shutter?  */
            CCD_HAS_COOLER     = 1 << 6, /*!< Does the CCD have a cooler and temperature control?  */
            CCD_HAS_BAYER      = 1 << 7, /*!< Does the CCD send color data in bayer format?  */
            CCD_HAS_STREAMING  = 1 << 8, /*!< Does the CCD support live video streaming?  */
            CCD_HAS_WEB_SOCKET = 1 << 9, /*!< Does the CCD support web socket transfers?  */
            CCD_HAS_DSP        = 1 << 10 /*!< Does the CCD support image processing?  */
        } CCDCapability;
