Just a short note to say I have the following working:

- OLED display interface which shows a % from 0 to 99
- Sockets server (for receiving enquires)
- Sockets client (for sending updates)
- DHCP and DNS lookup

And something rather cool - Audio recorder and playback. The PIC will take line level audio input and stream it over TCP, as well as receive audio (8Khz sampling 8 bit, voice suitable) over ethernet TCP and produce a line level audio output using the PWM module.

Next is to try the HTTP server, and use MQTT-SN.
