cc1101-spin

This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for Texas Instruments CC1101 low-power ISM-band (sub-1GHz) RF transceiver.

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), ~5MHz (P2)
  • Over-the-air (OTA) data rate from 600 Baud to 500kBaud
  • 2FSK, 4FSK, GFSK, ASK/OOK, MSK modulation formats
  • Set common RF parameters: Receive bandwidth, IF, carrier freq, DC block filter, RX Gain, TX power, FSK deviation freq, channel spacing
  • Set number of preamble bytes
  • Set function of CC1101's GPIO pins
  • Address filtering
  • Options for increasing transmission robustness: Data whitening, Manchester encoding, FEC, syncword
  • RSSI measurement

Requirements

P1/SPIN1:

  • spin-standard-library
  • P1: 1 extra core/cog for the PASM SPI engine (none if bytecode-based engine is used)

P2/SPIN2:

  • p2-spin-standard-library

Compiler Compatibility

Processor Language Compiler Backend Status
P1 SPIN1 FlexSpin (6.9.4) Bytecode OK
P1 SPIN1 FlexSpin (6.9.4) Native/PASM OK
P2 SPIN2 FlexSpin (6.9.4) NuCode OK
P2 SPIN2 FlexSpin (6.9.4) Native/PASM2 OK

(other versions or toolchains not listed are not supported, and may or may not work)

Limitations

  • TBD
