how to activate the red light in MC67

问题

i'm working on MC67 with windows mobile 6.0 and Motorola symbol.dll.

I need to light the red light in the device. i looked at the Motorola example and they don't show a way to do it, which makes me think there is no way to do it with symbol.dll.

is there a different way to do it? or do you know a general way to light the red led in the MC67? i'm talking on the red light because i already succeeded lighting all the others using Motorola Symbol.dll

回答1:

There is a class LED in Symbol.Notification namespace (EMDK .Net by Motorola).

I'm not tried but i think it helps you to solve your problem.

All LEDs on WM are normally accessible using the NLED API. The problem is that you have to find the ID for the red LED yourself:

First get the number of LEDs:

    NLED_COUNT_INFO cInfo;
memset(&cInfo, 0, sizeof(cInfo));
NLedGetDeviceInfo(NLED_COUNT_INFO_ID, &cInfo);

Then check each LED ID using LED ON/OFF (some support BLINK):

/*
struct NLED_SETTINGS_INFO
{
UINT    LedNum;                 // @FIELD   LED number, 0 is first LED
INT     OffOnBlink;             // @FIELD   0 == off, 1 == on, 2 == blink
LONG    TotalCycleTime;         // @FIELD   total cycle time of a blink in microseconds
LONG    OnTime;                 // @FIELD   on time of a cycle in microseconds
LONG    OffTime;                // @FIELD   off time of a cycle in microseconds
INT     MetaCycleOn;            // @FIELD   number of on blink cycles
INT     MetaCycleOff;           // @FIELD   number of off blink cycles
};

*/
NLED_SETTINGS_INFO settings; 
memset(&settings, 0, sizeof(settings));
settings.LedNum= id;
/*  0 Off 
    1 On 
    2 Blink */
settings.OffOnBlink= onoff;
settings.TotalCycleTime=1000;
settings.OnTime = 500;
settings.OffTime=500;
settings.MetaCycleOn=5;
settings.MetaCycleOff=5;

if (!NLedSetDevice(NLED_SETTINGS_INFO_ID, &settings))
{
        DEBUGMSG(true,(L"NLedSetDevice(NLED_SETTINGS_INFO_ID) failed"));
}
else
{
        DEBUGMSG(true,(L"NLedSetDevice(NLED_SETTINGS_INFO_ID) success"));
}

PhoneGap has a CS interface for the above C API: https://github.com/hemisphire/phonegap-winmo/blob/master/NotificationCommand.cs

The above works on all WM devices not only Motorola. It is a more general approach than using OEM SDK which will not work on other devices.
