P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the Si446x series ISM-band transceiver ICs

si4463-spin

---

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for Silicon Labs Si446x-series transceivers

IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.

Salient Features

• SPI connection at up to 1MHz (P1), TBD (P2)
• Set common RF parameters: carrier frequency, TX bitrate, modulation (2/4FSK, GFSK, 2/4GFSK, OOK, and CW for TX testing), frequency deviation
• Supports on-air bit rates from 100bps to 1Mbps
• Options for increasing transmission robustness: Syncword, preamble
• Supports setting preamble length

Requirements

P1/SPIN1:

• spin-standard-library
• P1: 1 extra core/cog for the PASM SPI driver

P2/SPIN2:

• p2-spin-standard-library

Compiler Compatibility

• P1/SPIN1: OpenSpin (tested with 1.00.81)
• P2/SPIN2: FastSpin (tested with 4.1.10-beta)
• BST (incompatible - no preprocessor)
• Propeller Tool (incompatible - no preprocessor)
• PNut (incompatible - no preprocessor)

Limitations

• Very early in development - may malfunction or outright fail to build
• No working TX or RX code yet

TODO

• Get CarrierFreq working
• Verify simple transmission
