Hello,

I work on lwIP 1.3.2 with a freeRTOS.
I have implemented a PPP communication with a 3G USB key.
Now i want to implement an ethernet communication with an adaptator USB/rj45.
I found the file ethernetif.c where i had to implement:
low_level_input()
low_level_output()
low_level_init()
I wonder if it's all ?
Is there any others functions?

I wonder where in RAW API,  can  i select PPP or ethernet?
Now i initialise ppp and tcpip. And ppp_thread "scan" the usb interface.
                    pppInit();
                    mem_init();
                    tcpip_init();
                    pd=pppOpen();
                    // waiting for pppOpen   [...]
                    pcb = tcp_new();
                    tcp_connect();
With ethernet i don't know how it works?
I wonder if i should create a thread?

Thanks for your help

regards

Nicolas
