Frank Vannieuwkerke / Mbed 2 deprecated LPC1768_Mini-DK_EasyWeb_DM9161

LPC1768 Mini-DK EasyWeb application with SPI TFT output. Started from EasyWebCR and modified for DM9161 PHY support.

Dependencies:   Mini-DK mbed

This is a very basic EasyWeb application.

No error checking is performed during initialisation.

Information

If the webpage is not reachable or the 'Webserver running' message does not appear, press the reset button on the Mini-DK and wait until the message 'Webserver running' appears.
This happens sometimes when powering up the Mini-DK because the DM9161 reset pin is NOT controlled by the LPC1768, it is directly connected to the reset button.
