This tutorial shows how to prepare the system running on the VisionSOM-6ULL module and the VisionCB-6ULL-STD carrier board to support the DLPDLCR2000EVM projector kit. The projector can be connected to the RGB LCD Connector of carrier board using an appropriate adapter. The example gerber files are provided here: [LINK DO GERBERÓW].

== Preparing the device tree file ==

The example is based on the available [http://ftp.somlabs.com/VisionSOM-6ULL/SoMLabs-VisionSOM-6ULL-Debian-2020-03.zip Debian image]. The device tree file can be modified according to [https://wiki.somlabs.com/index.php/Customizing_the_Linux_kernel this tutorial].

The projector module requires some changes of the timings used by the original system to support the parallel display interface. Changes need to be applied to the original somlabs-visionsom-6ull.dts file. The configuration of the LCDIF interface timings is shown below:

<pre>
&lcdif {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcdif_dat
&pinctrl_lcdif_ctrl>;
display = <&display0>;
backlight = <&backlight_0>;
status = "okay";

display0: display {
bits-per-pixel = <16>;
bus-width = <24>;

display-timings {
native-mode = <&timing0>;
timing0: timing0 {
clock-frequency = <26000000>;
hactive = <640>;
vactive = <480>;
hfront-porch = <14>;
hback-porch = <12>;
hsync-len = <4>;
vback-porch = <9>;
vfront-porch = <2>;
vsync-len = <3>;

hsync-active = <0>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <0>;
};
};
};
};
</pre>

After compilation, the new dtb file can be copied to the target system.

Configuring the system

The projector board requires some additional configuration and enabling using the I2C and GPIO interfaces. Setting the correct signal source and image resolution is realised using the i2cset tool and the GPIO is controlled using the /sys/class/gpio subsystem:

<pre>
echo 1 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio1/direction
echo 1 > /sys/class/gpio/gpio1/value
i2cset -y 1 0x1b 0x0b 0x00 0x00 0x00 0x00 i
i2cset -y 1 0x1b 0x0c 0x00 0x00 0x00 0x07 i
i2cset -y 1 0x1b 0x0d 0x00 0x00 0x00 0x02 i
</pre>

This configuration may be also written into an init.d script (/etc/init.d/projector) with permissions for execution:

<pre>
#!/bin/sh
# /etc/init.d/projector: Configures the connected projector
### BEGIN INIT INFO
# Provides: projector
# Required-Start: $x11-common
# Required-Stop: $x11-common
# Default-Start: 5
# Default-Stop:
# Short-Description: configures the projector I2C registers and gpio
### END INIT INFO

case $1 in
start)
echo 1 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio1/direction
echo 1 > /sys/class/gpio/gpio1/value
i2cset -y 1 0x1b 0x0b 0x00 0x00 0x00 0x00 i
i2cset -y 1 0x1b 0x0c 0x00 0x00 0x00 0x07 i
i2cset -y 1 0x1b 0x0d 0x00 0x00 0x00 0x02 i
;;
esac
exit 0
<pre>

<pre>
chmod a+x /etc/init.d/projector
</pre>

In order to run the script automatically after boot, the update-rc.d needs also to be called:

<pre>
update-rc.d projector defaults
</pre>
