In one of our systems, I want to add a simple email feature. I have email working on a wireless modem, but some of our customers want a direct connection to their network. Some time ago, I put a footprint for a ENC28J60 chip on our board, since the LPC2148 doesn't have ethernet built in. I haven't been able to find stack code written for the Keil compiler for this purpose. I saw that...

I am trying to diagnose watchdog timer resets on our LPC2366 parts. I think I can create a WDINT interrupt rather than to have it just reset the processor but does anyone here know if I can analyze where the code was when the timeout occurred ? Is this similar to diagnosing a data abort (which we do)... Is the last instruction located at address R14 -8 like it is with dabt's ? Or can someone...

I'm creating a data logger using the LPC2129 and need to store configuration data, even when my SD card might become corrupted. I'm trying to use code from AN11008, using FLASH as EEPROM, modified to store a single, short text file. I think my read functions work properly, but writing to EEPROM seems to fail. I'm having trouble wrapping my head around all of this, so I would really appreciate a...
