I believe they are set to input so they will be floating. You need to do the following to set turn the output enables on.. OED = 0xff; Note that IFCFG1 and WORDWIDE can affect port D (they will switch it to its alternative function FD[15:8]) Hope that helps :) BTW I found it quite helpful to configure UART 0 and write out debug messages to it (depends if you need both UARTs for your application though). -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
