* Parallel CMOS Image Sensor with UART Control Interface @ 2011-07-25 8:43 James 2011-07-26 19:40 ` Sakari Ailus 0 siblings, 1 reply; 8+ messages in thread From: James @ 2011-07-25 8:43 UTC (permalink / raw) To: linux-media Dear all, Does anyone came across a v4l2 Linux Device Driver for an Image Sensor that uses Parallel CMOS H/V and can only be control by UART interface instead of the common I2C or SPI interface? A similar sensor is the STMicroelectronics VL5510 Image Sensor although it support all 3 types of control interface. (http://www.st.com/internet/automotive/product/178477.jsp) Most or all the drivers found I found under drivers/media/video uses the I2C or SPI interface instead I'm new to writing driver and need a reference v4l2 driver for this type of image sensor to work with OMAP3530 ISP port on Gumstix's Overo board. I just need a very simple v4l2 driver that can extract the image from the sensor and control over it via the UART control interface. Any help is very much appreciated.

Hi James, I think there has been a recent discussion on a similar topic under the subject "RE: FW: OMAP 3 ISP". The way to do this would be to implement platform subdevs in V4L2 core, which I think we don't have quite yet.

I found it from the archive at http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/32700/focus=32721 I read through the threads and see that I'm indeed in similar situation with Alex. We both have sensor that output CMOS H/V image and only have UART/RS232 for control of the sensor operations via sending/reading packet of bytes. i.e. AGC, contrast, brightness etc.. Since the thread ended on 29-Jun, is there anymore update or information? As I've a MT9V032 camera with Gusmtix Overo, I was hoping to rely on the MT9V032 driver as a starting point and adapt it for the VL5510 sensor using only the UART interface.

As a quick hack, to start with, you can still use an I2C subdev driver. Just remove all I2C-related code from the driver, and register a fake I2C device in board code. That will let you at least develop the driver and test the UART interface. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 8+ messages in thread

Probably obvious, but just to have it mentioned in this thread, such UART driver should certainly be implemented as a line discipline.
