How to update firmware

[mrodz]

In case the steps are not clear:

1. Clone this repo on your machine (Linux is practically required).
2. Install the Arduino Desktop App (either `sudo apt-get install arduino or visit their website).
3. Open show_main.ino in the app.
4. Manually zip all of the folders in /libraries, then click Sketch > Include Library > Use .zip for each one to add them to the Arduino workspace.
5. Linux: open the terminal and make sure your USB device is showing in the kernel. cat /dev/ttyUSB0 shouldn't throw an error. the only valid "ports" in the Arduino app must start with USB (ttyAMA0 and others are NOT valid!)
   • If you use a data micro-USB connector, it might auto-fill this part for you. If not, the board is technically considered an Arduino UNO.
6. Ensure your device is connected using a data cable; chargers will not work. Identify a data cable by the USB trident on both connectors and the increased thickness of the base.
7. Quite possibly the most critical of all: KEEP THE DTR RESET JUMPER ATTACHED ON ITS TWO PINS.
   
8. In the Arduino App, hit Ctrl+U. Boom! You updated the Show2.

Important!

In order to use the product, TAKE OFF THE DTR RESET JUMPER and hit the reset button. Otherwise, this component will just continuously boot. Save the cap, in case you ever want to compile and downgrade.

Happy Hacking!
