April 21th, 2023 - This document explains how to use the new Picam v3 with a beamed patern via a projector (hdmi).

Prerequisite

• Raspberry pi 3b+ / 4
• Xangle OS image 10.0.0 or more recent. Get it here: https://drive.google.com/file/d/12a7xuFim--JtPfR6v4ptOgPPIWgTFj87/view?usp=sharing
• Xangle client version (in status page) should display 9.0.0 or newer
• XangleCS 2023-04-21 or newer

Projector Mode (Beta)

1- Enable experimental projector mode in the advanced settings:

2- On the dashboard, click on the trigger mode and choose "Projector"

• If you need to change the image you want to project, make sure it's a 24 bit RGB bitmap (bmp) image and save this image as "projector.bmp" in the src/client/assets/images folder of your xangleCS install

3- Plug an HDMI display on any of the raspberry pi with a picam connected to XangleCS and reboot it. The picam is required to get the sync signal for the HDMI output.

4- If you have some LED lights, make sure the associated pi registers with xangle (in status page). These pis (with LEDS) do not require a picam connected.

5- Once everything is connected, Press AND HOLD the trigger button on the dashboard**.** The projector.bmp image and the configured LEDS should be displayed as long as you hold the button.

6- Release the trigger button, 2x images will be captured in quick succession. The first image should capture the projected bmp and leds, the second will be without projection and the second light configuration.
