Hallo all ;-)

I am new in this area and I need for my project 2 UART connections. First for RS-485 and second for GPS. I saw that lpc1517 (LQFP64) has 3 USART but in data sheets I founded only on PIO0_13 U0_RXD and on PIO0_18 U0_TXD. So my question is on what pins are U1_RXD and U1_TXD?

Thanks

No :D

This U0_RXD/TXD setup is the default ISP setup (= if you are booting into ISP).

Chapter 8.4.2 'Movable functions' is describing how SWM (= Switch Matrix) can be used to switch this U0 / U1 / U2 functions to pins :O

So just select a pin and switch the desired function to this pin :)

Thanks R2D2. I told You that I am new in using microcontrollers :)
So simple thing but I did not know it hahaha
