Based upon the recent discussions concerning the UART TX FIFO, I have updated my UART Test w/ Blinky Lights program in the files section. The new (totally undescriptive) name is UT050418A.zip. The ISR code now checks if the FIFO is enabled when servicing a THRE interrupt. If so, 16 characters are loaded into the UART. If not, only a single character is loaded. Caution - I no longer have the eval board for which this code was originally written. I have however tested UART0 operation on another LPC board and merged the edits into the uartISR.c file for both UART0 & UART1. Enjoy -Bill Knight R O SoftWare & http://www.theARMPatch.com
