Sharp Memory LCD BoosterPack 96
|
This Sharp Memory LCD BoosterPack features a 1.3" 96x96 pixels screen in black and white and two touch sliders.
Connection is done through SPI, software or hardware, and uses 3 additional pins only to be added to the SPI pins. Touch requires 6 pins. The Sharp LCD display doesn't include GRAM or graphic RAM. So it takes 96 rows x 96 pixels per row / 8 pixels per byte = 1152 bytes from the SRAM of the MCU. Unfortunately, this makes the Sharp memory display impossible to use with the MSP430G2 LaunchPad. The new LaunchPads MSP430F5529 and MSP430FR5969 pack enough SRAM to manage the screen. |

Technology
|
Actually, the screen doesn't display black and white pixels but rather reflective and non-reflective pixels.
Consider the activated pixels as mirrors. This ensures good readability at sun light. The screen uses very low power, and only needs to be refreshed once per second. The screen may sound familiar, as it is already used in smart-watches. |

However, the readability depends heavily on the angle of vision.
A small change can make the screen difficult if not impossible to read. Click to enlarge |

However, with a correct orientation, the screen offers a contrast high enough to allow a smartphone read this QR code.
See the Fast and Easy Connection with QR-Code project for more information. |

The screen comes with libraries and examples for Code Composer Studio as well as Energia.
