From the Forums: a homemade cell phone with a GUI, calling, SMS, and games #FromTheForums #Adafruit @Adafruit

From the Adafruit Forums, user jim_lee posts a homemade graphical cell phone project!

This is the “home” screen (center, above). Across the top is the menu bar that can have text, icons, what have you. This screen has battery charge and RSSI indicators. Across the bottom, on the home screen is my five “standard” phone icons. Phone, SMS, Contacts, Calculator, Settings/Debug.

The project uses a ton of parts from Adafruit: An Adafruit 2,8″ display breakout with SD card reader, an Adafruit Feather FONA, and a Teensy 3.2. As for the software:

The phone runs on what I’m calling litlOS It’s basically an Arduino sketch swapper. There is an object called a panel and that has setup() & loop() methods. You can get your sketches running independently, then just wrap them into a panel object and the OS takes care of swapping them in and out of memory. Actually there are also close() and closing() methods. One can be called to quit a panel and the other is called when a panel is shutting down.

SMS panel for texting. Notice all the sub-panels have a red X in the top left corner. This takes you back to the home panel. When you send a text message it goes on the screen as yellow. If its successfully sent it turns to green. Incoming text are white. The nickname of the person your texting is at the top of the panel.

The code is available on GitHub at https://github.com/leftCoast/Arduino – Jim writes:

Maybe you see this as a neat toolset for programming Arduinos. It is, in a way. But really, its more like the huge pile of mess on my desk. Many things don’t work, some are missing parts. Some will never work. There’s probably spilled drinks and long dried out half eaten hamburger in here. This is just a swirling turmoil that new ideas spawn from.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
