Hello all,
I am using the LPC LINK 2 as an evaluation board. So far, that works fine. Besides USART2 is it possible to get access to USART0 or USART3. I tried to configure the respective pins according to the Manual but that doesn't work. It seems that there is a problem with pin muxing, as activating pull up also does not work.
Thanks in advance
JoeE

Thank you for the hint. UART0 works on that pins. UART3 still doesn't. But 2 UARTs is ok for me.

you can get the schematic here

UART0 on P6_4, P6_5
UART3 on P2_3, P2_4

however, the startup code probably already maps these pins to some other peripheral,
so you will have find where that code is, and disable that code before your code can enable the pins as a UART.
