Help setting up interrupr driven UART on 52223

PopsStack — Thu, 15 May 2008 23:35:09 GMT

Can someone please assist with setting up interrupt driven UART.

I see that reference is made to the CTS line being sensed for interrupt t oocurr or am I missing something here. I am not using CTS only RX,TX, GND lines.

Am try to get data out of a GPS so need to get the data out and stash it in a buffer to then parse it for the NMEA sentences.

Thanks

Hi PS

The RTS + CTS are not needed and can be ignored.

See the following:

the M52223 UARTs are compatible to the M5223X and code is identical.
