UART0, LCD, etc. on blackfin ADSP 707

Hi, there

We bought a new BLIP2 evaluation board (Blackfin ADSP-707) and would like to test some image processing algorithms.

My questions are:

1. Can I connect a LCD and direct the outputs of the images from the sensors to the LCD ? My idea is to run the VOS and direct the outputs to LCD. It looks like there is a 40-pin header on the board that we can use. I found a blackfin Landscape LCD EZ-Extenter board online, but it says that it works with blackfin ADSP 5xx. Not sure if it works with my processor which is 707. 

2. I can't find the connection points to TX/RX of UART0 on the board. I looked through the schematics and had trouble locating the exact solder points on the evaluation board for TX/RX of UART0.

3. Is there any GPIO pins on the board that we can use ? I only saw several Test Points that I might be able to solder physical pins to it, but not sure if any of them is associated with the GPIO pins.

Any comments/suggestions will be appreciated.

Regards,

Eric

    >> The EVAL-BFLLCD-EZEXT  (Blackfin Landscape LCD extender) can plug directly onto the expansion interface II of the ADSP-BF526 EZ-Board and the parallel peripheral interface (PPI) connector of the ADSP-BF537, ADSP-BF538, or ADSP-BF548 EZ-KIT Lite boards. It uses stamp connector for the interface and which is not available in the BLIP2, so it cannot be interfaced to BLIP2.

    2. I can't find the connection points to TX/RX of UART0 on the board. I looked through the schematics and had trouble locating the exact solder points on the evaluation board for TX/RX of UART0.

    >> The ADSP-BF707 processor has two built-in universal asynchronous transmitters (UART0 and UART1). UART0 is not used for UART functionality in the BLIP2, rather it brought to the Snap sensor interface connector, see below.


    UART1 is connected to an FTDI, FT232RQ, USB to UART converter IC (U15). For more information, refer to the UART1 example, which is included in the ADZS-BF707-BLIP2 Board Support Package.

    3. Is there any GPIO pins on the board that we can use ? I only saw several Test Points that I might be able to solder physical pins to it, but not sure if any of them is associated with the GPIO pins.

    >> Test points you cannot use in the BLIP2 as GPIOs. 

    I can see only the below connector where the GPIOs brought to a connector. The SPI1 signals are multiplexed with GPIOs of PORTA.

      

     

    Did you get a chance to look at ADSP-BF707 Ez-kit manual, where you can have the above provisions.
