Interrupt UART0 DM368

Javier Hernandez

Hello,

I am using the EUCDK DM368 development kit from Leopard. In this project I need to know when data is received with an interrupt so I can process the data. The UART0 TX goes to GIO18 and the RX goes to GIO19, the UART0 is then go to a RS485 transceiver/receiver which eventually will go to another device. How can I set the interrupt to call a function that process the data?

Regards,

Javier

But is there a way to use an interrupt with termios or is the best way is to spawn a thread and loop waiting for a byte to coming? Remember I am only using RX/TX lines.
