Updates

Dec 6 2019 - Official Firmware Available

Official firmware for the Omega2 Dash is now available!

If you have a beta unit, follow these instructions to upgrade to the official firmware:

• Make sure your Omega2 Dash is connected to the internet
• Back up any files that you don't want to lose! The upgrade will erase everything on the filesystem
• Run the following commands:

cd /tmp
wget http://repo.onioniot.com/omega2/images/omega2dash-v0.3.2-b233.bin
sysupgrade -F -n -v omega2dash-v0.3.2-b233.bin

Dec 6 2019

We've put together an program that can serve as the starting for Omega2 Dash programs using the LittleV Graphics Library.

• Learn more about the example program here: https://github.com/OnionIoT/Omega2-Dash#littlevgl-example-program
• See the repo here: https://github.com/OnionIoT/lv_example

Out of the box it supports:

• The Linux Framebuffer - will draw to the Omega2 Dash display
• The XPT7603 touch input device on the Omega2 Dash
• A makefile and instructions to build it as an OpenWRT package
• A small demo

Use this to get started with your own lvgl programs!

Compiled demo of LittleV Graphics Library with touch input. See how to run it on your Omega2 Dash [here]

Running the Omega's terminal on the display:

Run sh > /dev/tty0 on your Omega2 Dash. Everything you type from then on will show up on the display and not in your terminal window.
Hit ctrl+c to exit.

you can check out this tutorial

You need to edit the file /etc/config/wireless
Under config wifi-iface sta
set option disabled '0' to option disabled '1'

reboot your omega2+ and it will not try to scan or connect to any WiFi.

@William-Scott

My only concern with using a FET as the power supply is depending on the model it may not supply enough pick current for the normal boot process. I like your suggested setup if we can find a FET that works in normal boot.

Breadboard dock would be a idea dock for the setup. would you mind coming up with a block diagram of the setup?

@György-Farkas

In our test we used a 1000uF polarized capacitor. The power supply is the one used in a the Expansion Dock. Check out the schematics here.

Here is another tutorial you an follow
https://onion.io/2bt-single-command-losantomega/

We have done some internal testing by manually adding a large capacitor between 3.3V and GND while the system is running to emulate a large load. This is enough to introduce a brownout.

What kind of setup do you have in mind so we can programmatically change input voltage?

@William Scott

We are happy to collaborate in coming up with an automated tests procedure. Doing it publicly here on the community is definitely the way to go. This way more people can contribute of rip the benefit of the test result.

Can you share what test setup you have in mind and specifically what input do you need from Onion side?

how are you connecting to WiFi? wifisetup command? Can you share you console log?

Nice project, we will get you on Onion news letter in the coming weeks and you will be able to get some free Omegas for being featured ;)
