| Connection You can attach an external front panel LED to the position marked D2. This duplicates the function of the onboard LED. Solder the pin header strip to pins 19-38 of JP4 on the application board There should be marker pips printed on the board by pins 19-20 and 37-38 which help to locate the header correctly. See Illustration. Connect the ribbon cable from this header to the box header on the memory card interface, making sure pin 1 in the memory card interface goes to pin 19 on application board JP4. Optionally mount the card to your hardware using the mounting holes provided. If you are already using asynchronous serial port 2, you must use the SPI connection for the memory card. If you do not need asynchronous serial port 2 in your application, you can use its data lines as a higher speed connection for the memory card. To do this on a 5811 application board you must remove the serial interface IC U4 from its socket on the application board. Follow the configuration instructions below for your chosen connection method. |
