LPC804 UART Example

LPC804

UART demo

IAR EWARM 8.2

I am using the LPC804 UART example provided in the IAR example pack for the LPC804. I am using the LPC804 eval board. The UARt code builds and runs but I never get the buffer empty flag, for example it will hang here:

while ( !(UARTx->STAT & TXRDY) );

or here

while ( !(UARTTxEmpty & 0x01) );

Anyone get this example to work?

Thanks

Rich

Hi Richard Soennichsen,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'd like to replicate the phenomenon you mentioned, so whether you can up a compile-able demo code and introduce the testing process in brief.
Looking forward to your reply.
Have a great day,
TIC
