Using your badge
With your badge you will receive a booklet explaining how it's done. If you have any problems, please come to the Badge Operation Center and we will help you.
After you have assembled your badge you can just use the tiny switch at the bottom of the screen to turn your badge on. Alternatively you can use any USB power source. If you turn your badge on for the first time (or if for some reason it has reset itself) you will get some on-screen information while we try to download the newest set of software. This doesn't always work on the first try, you might have to use "reset" to try a few times
If at any point you want to restart your badge you can just press the reset button on the back below the display ribbon.
Changing your name
- Press 'Menu'
- Select the 'Settings" app
- "Change Name" and press 'A'
- Use the joystick and 'A' key to enter your name
- Press 'Menu' to save your name and reset the badge - your name should now be displayed!
Installing new apps
- Press 'Menu'
- Select 'Badge Store' app and press 'A'
- Select "Install"
- Select a category and then an app. Wait until you see the description and press "A" to save it.
- Press B a few times (or alternatively MENU) to restart your badge
- On the home screen you can now press MENU to find your newly installed app.
Your TiLDA Badge has built-in wifi support. It should all just work if you're at the campsite, but if you're on your own network you might have to tell the badge about it. For more information please have a look here: WiFi
The badge charges via a microUSB socket, and takes about 2-3 hours for a full charge. The red charge LED to the right of the display ribbon on the back will extinguish when charging is complete.
Nothing works! Help!
Don't worry, you can always "factory reset" your badge. Please follow these instructions: Resetting
If everything else absolutely fails, you can try following these instructions (advanced): TiLDA_MK4/Firmware_Update
Hacking your badge
One of the main goals of TiLDA is to make hacking it as easy as possible. All you need to do so is a computer with USB and your badge.
- tilda-tools - the one-stop interface for all your badge needs
- Step-by-step - to make it as easy as possible to get going
- 3 Ways to run code on your TiLDA
- Badge Store Submissions - Share your creations with others
- Code Structure - How the python code is structured
For more information about the functions available please have a look at the Badge API section of this page.
In case you're more interested in what makes the hardware tick and your confident with C++ and microprocessors then you can work directly with the micropython code that runs TiLDA: How to build the firmware from scratch
All code used is hosted on Github. Contributions and PR are very welcome!
- https://github.com/emfcamp/Mk4-Backend (powers the badge store)
- documentation - General Micropython libarary
- uGFX - The TiLDA LCD colour screen
- CC3100 - The wifi chip
- RTC (real time clock)
- SIM800 (GSM/Phone/Bluetooth)
- import tilda (our custom micropython module)
- SPI SPI
- please add
On top of the build-in modules above we have also created a bunch of helpful libraries written in python. If you go through the bootstrap process or use the App Library you should always have a full set of those on your badge. If for some reason this isn't the case you can download our repository from https://github.com/emfcamp/Mk3-Firmware and copy the
lib folder onto your badge.
for now please have a look at the libraries themselves: https://github.com/emfcamp/Mk4-Apps/tree/master/lib
(feel free to add additional ideas, and create links new wiki pages to on-going projects, perhaps someone will want to contribute)
