TM4C1294NCPDT: TI RTOS NDK interrupt

Part Number: TM4C1294NCPDT

Hello,

My system works with an Ethernet connection and 5 UARTs. 
I receive a frame on the ethernet which I retransmit in part depending on the frame elements at each of the Uart. 
These Uart pass this data to devices which return values on the Uart. 
The Uarts values are positioned in a frame and sent back by Ethernet.

Following your advice I use NDK for ethernet. When I receive a frame from the PLC, 
it would be necessary to generate an interrupt to then analyze the frame and distribute it in the different Uarts' Task.

Is it possible to generate interrupt with NDK when a frame is receive on ethernet? 
Have you got an example ?

Thanks in advance

Best regards

Hello Christophe,

Our NDK expert is out of office this week but I will try my best to help answer this.

For starters, have you reviewed what we have provided from the NDK in terms of examples? We have a new app note that has multiple examples with it: https://www.ti.com/lit/pdf/spma080

In this some of these examples, we have a task setup to handle data processing:

/*
 *  ======== tcpWorker ========
 *  Task to handle data processing when data is received by client.
 */
Void tcpWorker(UArg arg0, UArg arg1)

I would think that would work for what you want. That example in particular is enet_tcpecho_client_tirtos
