製品概要

This EZ-Extender is a daughter board that extends the capabilities of certain EZ-KIT developments boards, facilitating connection of Blackfin BF52x, BF53x and BF54x family processors to a landscape LCD. It connects to the ADSP-BF526 EZ-Board / EZ-KIT Lite, ADSP-BF537 EZ-KIT Lite, ADSP-BF538 EZ-KIT Lite, and the ADSP-BF548 EZ-KIT Lite development boards over their EI2 interfaces.

Supporting a 3.5” landscape QVGA (320x240) display from SHARP which can operate at VDDIO from 1.6V to 3.6V, it facilitates both normal and low power applications. The low cost touchscreen controller for this display is the Analog Devices AD7879, a small 16 pin LFCSP package ideal for low power applications.

The EZ-Extender employs the Analog Devices AD7147-1 programmable controller designed for use with capacitance touch sensors. The capacitance controller interfaces to the Blackfin processor over a simple two wire interface (TWI). The other end of the controller interfaces to external capacitance sensors such as capacitive buttons, scroll bars, and scroll wheels. No external power supply is required for the EZ-Extender.

Note: The Blackfin Landscape EZ-Extender has limited compatibility with the ADSP-BF537 EZ-KIT Lite. Below are the following limitations:

  • The Sharp LCD and the AD7879 (LCD Touch Controller) can be used together or the Sharp LCD and the AD7147-1 (Capacitance Touch Controller) can be used together.
  • The AD7879, AD7147-1, and the Sharp Display cannot all be used simultaneously.
  • This is due to limited GPIO availability on the BF537 Stamp PPI Interface.
  • All other supported products (BF526, BF538, and BF548 EZ-KITs) allow a user to use all three simultaneously.
