Multiple UARTs on the LPC824 with LPC Open ?

Not sure if this belongs here or in the LPC Open forum...

I have an application that needs to handle full duplex data on 2 UARTs simultaneously.  I will definitely go interrupt driven but could go with either the ROM routines or the ring buffer example. 

It doesn't look like either of these LPC Open examples are inherently dual port capable.  Before I dig in, has anyone had any experience running 2 channels of the LPC Open UART code for UART0 and UART1?   Hoping to leverage LPCOpen as much as possible.

I suppose I could run my slower port polled if necessary.  One is 115.2K and the other only 2400.

Thanks!
Dave

OK, will give it a shot.  I'm no C guru yet so it wasn't immediately obvious how to use or modify the interrupt driven LPCopen reference code to support two instances.   If anyone has done this before I'd appreciate any comments.

Regards,

Hi Ll_Dave,

I do not see why any of the UART LPCOpen examples will have issues with using two UARTs. It is true that in general the LPCOpen examples only setup and use one UART/SPI/I2C but there shouldn't be any limitation to one UART -- just setup the necessary pins, clocking, IRQ, etc. for another :)
