Introduction

Toradex tests and recommends the following displays to be used with its Computer on Modules (CoM):

For these displays, Toradex provides an easy way to set-up and get running. This article explains how to set up these displays on Torizon.

This article complies to the Typographic Conventions for Torizon Documentation.

Configure Recommended Displays with Torizon

Pull the Torizon Debian Container

On the Toradex Computer on Module (CoM) terminal , pull the container:

# docker pull torizon/arm32v7-debian-dev-tools

Run the Container

After the pull complete, run the container:

# docker run -it --rm --privileged -v /dev:/dev -v /boot:/boot torizon/arm32v7-debian-dev-tools

Enable overlay

To enable the overlay for your display, in the container on the Toradex Computer on Module (CoM), use dtconf as following:

## dtconf activate display_7_parallel_cap_touch.dts 

For Apalis i.MX6 you'll need a second overlay to enable the parallel display interface on this module.

## dtconf activate enable_parallel_display_apalis_imx6.dts

For capacitive touch you'll need an additional overlay in the form of touch_cap*.dts. The overlay file needed depends on your module and carrier board combination. The following command will list Toradex provided overlays:

## dtconf status

Once you've identified the correct overlay for your setup you may use dtconf activate <file> to apply your capacitive touch overlay.

## dtconf activate display_10.1_lvds_cap_touch.dts

For Apalis i.MX6 you'll need a second overlay to enable the LVDS display interface on this module.

## dtconf activate  enable_lvds_display_apalis_imx6.dts

For capacitive touch you'll need an additional overlay in the form of touch_cap*.dts. The overlay file needed depends on your module and carrier board combination. The following command will list Toradex provided overlays:

## dtconf status

Once you've identified the correct overlay for your setup you may use dtconf activate <file> to apply your capacitive touch overlay.

## dtconf activate display_EDT7_parallel_res_touch.dts

For resistive touch you'll need an additional overlay as follows:

## dtconf activate display_EDT7_parallel_res_touch.dts

Apply overlay

Finally, once all overlay files have been enabled they can then be applied to the system with a quick reboot.
