Programming

Programming is easy! Like most Arduinos, you simply plug the board into your PC using a MicroUSB cable, select the board you want to program, and hit the upload button in the IDE when you're ready. The Pixel ships with the Arduino/Genuino Zero bootloader installed.

The Pixel is compatible with the Arduino's SPI and SD libraries. Communication with the display and MicroSD card are both handled through the SPI bus, which is broken out on a set of pads for a surface mount header.  The ATN pin replaces the reset pin on this header and acts as the CS pin for the MicroSD.  Pins 7, 8, and 9 (ORST, ODC, OCS) are also utilized to control the display.  

The Pixel is also compatible with Adafruit's graphics library. This library provides functions for blitting images, drawing primitives like lines and circles, and even includes bitmapped font support!

Lastly, if you ever need to modify the fuses or bootloader, the Pixel features an SWD header which is compatible with the Atmel ICE. On the final version of the board, this will be a through-hole header, so you can connect the ICE by inserting a pin header into its ribbon cable like so:

The Atmel ICE can be used to update the fuses and bootloader, but is NOT required for programming the board normally!

Open Source Hardware

The Pixel will be open source which means I'll make the schematics and PCB layout available, and you'll be free to modify the design as you wish and integrate it into your own boards - without ever needing to pay any royalties or licensing fees!

Risks and challenges

With the Pixel having been prototyped once already, and only some minor changes needing to be made to the design, there isn't much risk involved in this campaign. Last month, with the help of my manufacturer, over 400 Neutrinos (the Zero compatible microcontroller I developed which was the base for the design of the Pixel) were shipped all across the world to backers, so I have a very good idea of the costs involved and I anticipate no problems in delivering the boards to you!
