This demo is about driving TFT LCD by FlexBus module on MAPS-K22 board.

      MAPS-K22 brief description:

  • High performance Freescale ARM Cortex™ M4 SoC MK22FN512VLL12 with 120MHz core clock, 512KB Flash and 128K RAM.
  • Support Graphic LCD by Flexbus interface.
  • Power supply from Micro USB 5V.
  • Support ISO7816 smart card by UART interface.
  • Support connector for Peripheral, Application and Socket MAPS board.
  • SDK 1.0 Software release



FlexBus Overview

      The FlexBus module is a hardware module that:

  • Provides memory expansion and provides connection to external peripherals with a parallel bus
  • Can be directly connected to the following asynchronous or synchronous slave-only devices with little or no additional circuitry:
  • External ROMs
  • Flash memories
  • Programmable logic devices
  • Other simple target (slave) devices
