S1D13781 Reference design for mbedTM compatible platforms

The S5U13781R01C100 Shield TFT Controller board with an integrated Epson S1D13781 LCD controller can be used with some mbedTM compatible platforms.

Summary

mbed is a well-known software platform for ARM® based microcontrollers. It provides the tools and developer ecosystem necessary to create standards-based solutions for any kind of application, but with particular focus on Industrial applications. Further information is available on the mbed website at www.mbed.comNew window.

In order to use the S1D13781 Shield TFT board with mbed compatible microcontroller boards, some small modifications are required. Epson provides an easy to follow guide that details the required modifications. Also available is a simple graphics library designed to work with the mbed compilier, and instructional videos to help new users get started. These resources are available on Epson's website hereNew window. The S5U13781R01C100 board has been successfully tested with the ST Microelectronics Nucleo F303RE, F401RE and F411RE mbed compatible boards.

The S1D13781 Shield TFT Board adds support for up to WQVGA TFT graphics to the mbedTM based platform and provides a software library of simple graphics functions. It is designed to provide evaluation of the S1D13781 LCD controller and enables rapid prototyping on the mbed TM compatible board. It uses the mbedTMstandard SPI interface, providing a simple hardware connection which is powered by the mbedTMcompatible board. The S1D13781 Shield board includes two FPC connectors (40-pin and 54-pin) which can be used to connect to a WQVGA or QVGA TFT panel available separately.

The S1D13781 is a simple, multi-purpose Graphics LCD Controller with 384KByte embedded SRAM display buffer which supports RGB interface TFT panels. The embedded display buffer allows WQVGA up to 480x272 at 24bpp, or 480x272 at 16bpp (Main Layer) and 480x272 at 8bpp (PIP Layer) for two layer display. The S1D13781 is a flexible, low power, single chip solution designed to meet the demands of embedded markets and devices where total system cost and battery life are major concerns.

The S1D13781 Shield TFT Board can also be used to evaluate the low cost S1D13L01 LCD Controller which shares the same features as the S1D13781 except for BitBLT functionality*.

* See the S1D13781 and S1D13L01 Hardware Specifications for complete feature list.
