I am using LPC1769 micro controller and planning to use one of its serial (UART) port for PC communication.

It has 4 UART ports (UART0,1,2 and 3)

For PC communication purpose, can I use all ports or there is limitation on specific port?

How to check which is suitable for PC communication?

Thanks in advance.

  • \$\begingroup\$ If you are using NXPs LPCxpresso evaluation board for this, then the documentation that came with it should say which UART is connected to the debugger. Otherwise you could use a simple UART to USB bridge. \$\endgroup\$ – Funkyguy Jun 2 '16 at 20:56

As far as the chip is concerned, you can use any UART port for any purpose you like.

However, if you are using a particular evaluation board or a particular software library, these may impose additional limitations. You'll have to read the documentation associated with each.

  • \$\begingroup\$ Can I use any uart port for flash programming on serial port? \$\endgroup\$ – Electroholic Jun 1 '16 at 11:03
  • \$\begingroup\$ That would depend on the flash programming firmware (a.k.a. "bootloader"). Again, read the documentation. \$\endgroup\$ – Dave Tweed Jun 1 '16 at 11:29
