Easy e-paper?comes to your Feather?with this breakout that’s designed to make it a breeze to add a tri-color eInk display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
We’ve liked these displays for a long time, so wouldn’t a custom e-paper FeatherWing with buttons make a ton of sense??This ‘Wing is tested to work with?all?of our Feathers, from the ESP8266 to the M0. It has built-in memory buffering so it can work with chips as small as the ’32u4 and ‘328. It?does?use a lot of pins: the 3 SPI pins, and up to 4 control pins to manage the SD card slot and SRAM. Plus 3 optional buttons are available for Feathers with available pins.
The FeatherWing sports a?2.9″ tri-color (red, black, and white) display?with 296×128 pixels?with?black and red ink pixels and a white-ish background. Using our CircuitPython or Arduino libraries for the IL0373, you can create a ‘frame buffer’ with what pixels you want to have activated and then write that out to the display. Most simple breakouts leave it at that. But if you do the math, 296 x 128 pixels x 2-bits-per-pixel = 9.5 KBytes. Which won’t fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 9KB?
