Re: external apps addition to existing project Harmony V3
There are enough UDP examples in the demo applications that are part of the TCP/IP distribution:
- tcpip_udp_client, tcpip_udp_client_server, tcpip_udp_server
- berkeley_udp_client, berkeley_udp_relay, berkeley_udp_server if you prefer BSD API.
You can use the demo code that applies to you. The fact that the stack runs on a PIC32MX, PIC32MZ or any other platform is irrelevant (the only thing that's changed is the network driver, some I/O settings, etc.).
That is, once you have a demo working on your platform, you can use code from another demo application without any problem (provided that the proper stack modules are enabled).
You should add your code in the application files and never mess with the stack directly (unless you know what you're doing).
