New page

MT9M111 is an xxx 1,3 Mpixels sensor that can be found in the following commercial camera modules:
*
*

==Connecting the XXX module to the APF27==
*

===Description===
* CSI port (8 bits data + 4 bits control signals) is used to transmit images. (10 bits mode not usable on i.MX). These signals are available on the APF27Dev J9 connector (2,5V logic).
* I2C bus is used to configure the sensor. This bus is available on the APF27Dev J8 connector.
* Sensor core/IO power supply (2,5V) comes directly from J9 2,5V.

===Adaptation board===
* (Preliminary) Schematics and layouts (for [http://kicad.sourceforge.net/wiki/index.php/Main_Page KiCAD]) of an APF27 adaptation board are available [http://dl.free.fr/opT0rvWWZ here].

==Usage==
* Bring module out of powerdown by driving SSI3_TX (pin 30 of port C) & SSI3_CLK (pin 31 of port C) as GPIOs (through [[GPIOlib]]):
<pre class="apf">
echo 94 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio94/direction
echo 0 > /sys/class/gpio/gpio94/value; usleep 100000
echo 95 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio95/direction
echo 0 > /sys/class/gpio/gpio95/value; usleep 100000
</pre>

* Load corresponding drivers:
<pre class="apf">
# modprobe mx27_camera
Linux video capture interface: v2.00
mx27-camera mx27-camera.0: initialising
mx27-camera mx27-camera.0: Camera clock frequency: 33250006
mx27-camera mx27-camera.0: Using EMMA

# modprobe mt9m111
camera 0-0: Camera driver attached to camera 0
mx27-camera mx27-camera.0: mclk_get_divisor not implemented. Running at max speed
camera 0-0: Detected a MT9M11x chip ID 143a
camera 0-0: Camera driver detached from camera 0
</pre>

===Test===
* You can then use Armadeus "capture" demo tool to get images from the camera.
* First time you will have to set the camera module registers correctly (not done by the driver yet) by using a custom script ''ov9653_regs.sh'' available [here]. Here is how to proceed:
<pre class="apf">
# capture & usleep 400000 ; ./ov9653_regs.sh
</pre>
