Subject: [PATCH 0/7] em28xx: add basic support for the SpeedLink Vicious And Devine Laplace webcams
Date: Sun, 1 Dec 2013 22:06:50 +0100 [thread overview]
Message-ID: <1385932017-2276-1-git-send-email-fschaefer.oss@googlemail.com> (raw)
The SpeedLink Vicious And Devine Laplace webcam is using an EM2765 bridge
and an OV2640 sensor. It has a built-in microphone (STAC9753 AC97,
USB standard device class) and provides 3 buttons (snapshot, illumination, mute)
and 2 LEDs (capturing/mute and illumination/flash).
It is also equipped with an eeprom.
The device is available in two colors: white (1ae7:9003) and black (1ae7:9004).
For further details see http://linuxtv.org/wiki/index.php/VAD_Laplace.
The first 6 patches improve and extend the support for device buttons and LEDs by
- abstracting and generalize the button and LED handling
- adding a software debouncing mechanism for buttons connected to ordinary GPI ports
- adding support for analog capturing and illumination LEDs
- adding support for illumination buttons
Support for the audio/video mute button can easily be added later, but that requires to fix several audio issues first.
Fortunately, there is another bug that prevents the em28xx driver from detecting the audio part of these devices. :/
Patch 7 finally adds the USB IDs and the board defintion for these cameras.
The following limitations need to be addressed later:
- resolution currently limited to 640x480 (sensor supports 1600x1200)
- picture quality needs to be improved
- audio/video mute button doesn't work yet
Frank Schäfer (7):
em28xx: add support for GPO controlled analog capturing LEDs
