bg. WIRELESS CHAT

INSTRUCTIONS TO BUILD (solder, program firmware, run the application):

- How to get PIC18 SPI interface working (includes PIC18F26J50 to RFM69CW schematic)?

- How to get PIC32 SPI interface working (includes PIC32MX250F128B to RFM69CW schematic)?

- How to properly configure RFM69CW wireless transceiver and transfer data?

OPERATING RANGE:

RFM69CWs work flawlessly up to a distance of approximately 100 m with no need for an antenna amplifier. The actual range also depends antennas types. You can also use a short piece of wire as an antenna for communications between computers within the same room.

Wireless communications are really funny. The wireless chat example is based on PIC18F26J50 (firmware v2.6.5 or newer) and PIC32MX250F128B (firmware v2.8.7 or newer) microcontrollers. The application also needs LIB_PCUSBProjects v4.8.NET4(x64).dll or newer to be installed in the same directory as EXE file, but don’t worry, the example includes the library. Though application is basic and simple, it can make a huge difference when playing a social action game. An independent communication channel may not be seen or blocked by routers and firewalls… All you need is a pair of microcontrollers with a USB 2.0 connection to a PC. PIC18F26J50 and PIC32MX250F128B microcontrollers may be used.

The application is available as RFM69CW Transceiver Chat (x64).zip files in Dowmloads section
