Portable Wi-Fi Rotor Controller PWRC

PWRC is replacing the venerable AE-12 controller.
Introduces support for the widely available RCA rotators, which have limit switches and capacitor inside. Keeps compatibility with AE-12, by supporting Channel Master, RadioShack, AR-500 and other rotators.

I built this rotor controller for my portable operation on VHF/UHF contests and Field Day. The main goal was to be able to operate on 12VDC from a Solar / Battery power setup, easy installation and to be able to rotate my VHF/UHF antenna stack and a HF tri-bander. Using Wi-Fi network eliminates the control box and cables, to simplify the setup. On the field I can connect my laptop / tablet / smartphone directly to the rotor using it as a Acces point or it can be connected to existing Wi-Fi network. Rotator can be controlled simultaniousy via three interfaces.
Using any device (laptop/tablet/phone) with WEB browser to set it up and point-and-shoot to rotate antenae.

WEB interface can be completely customized by downloading, modifying and uploading file: rotor.html from the internal flash filesystem.

Running firmware V3B0 and above will serve any file uploaded to the flash file system back to the Web browser. There is a sample application to display Azimuthal map, created on Tom/NS6T Web site.
N1MM logger and DXLab suite (maybe others) can controll it with UDP packets. See N1MM Rotator Control page for details.
The versatile PstRotatorAz by YO3DMU can be used via telnet protocol. See the User manual how to configure it.
