Sharp Memory LCD

Sharp Memory LCDs are high pixel density, low power displays that don't need backlights. They draw in the region of 100uA while idle, so are perfect for always-on, battery-powered applications.

Wiring Up

Example Software

Just use the MemoryLCD (About Modules) module as follows:

SPI1.setup({ sck:B3, mosi:B5, order: "lsb", baud: 4000000 });

var g = require("MemoryLCD").connect(SPI1, B4/*SCS*/, B6/*EXTCOMIN*/, 128/*width*/, 128/*height*/, function() {
  g.clear();
  g.drawString("Hello",0,0);
  g.drawLine(0,10,g.getWidth(),10);
  g.drawString(getTime(), 0, 20);
  g.flip();
});

More details on how to draw are in Graphics.

Notes

• SPI must be set up with order : 'lsb' (the default is 'msb'), and the baud rate shouldn't be above 4000000
• Make sure you specify the correct width and height (either 96x96, 128x128, or 400x240 )
• Espruino toggles the VCOM pin (if specified) every 5 seconds. Sharp recommend 1 second but the longer time period allows Espruino to enter Deep Sleep and save a lot of power.

Buying

The LCDs come with a ~0.5mm ribbon on them so they're hard to connect to directly and you'll probably need a breakout board.

Sellers of LCDs on breakout boards are:

• MakerDyne 1.3" and 2.7"
• AdaFruit 1.3"
