[Version 1] Detecting When Someone Logs In


Recommended Posts

Here is the method I came up with. Seems to work on my laptop. Let me know what you think.

//Attempt to detect when a user logs in.
void WaitForUserToLogin(uint16_t timeToLogin)
{
    //Get value of keyboard leds just for caps lock.
    uint8_t caps = keyboard_leds & 0b00000010; //Second bit is for caps lock
    //If caps lock isn't on, turn it on.
    if(caps == 0)
    {
        usb_keyboard_press(KEY_CAPS_LOCK, 0);
    }
    //Wait a second before we begin checking.
    PDDelay(1000);
    //Wait for caps to be turned off.
    do
    {
        //Get value of keyboard leds just for caps lock.
        caps = keyboard_leds & 0b00000010; //Second bit is for caps lock
    }
    while(caps == 2);
    //Delay to allow time for the user to login.
    PDDelay(timeToLogin);
}
