This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the TI CC2500 2.4GHz ISM-band transceiver chip.
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.
- SPI connection at up to 1MHz (P1), up to 6.5MHz (P2)
- Supports setting carrier frequency from 2,400,000kHz to 2,483,500kHz
- Set common RF parameters: Receive bandwidth, IF, carrier freq, DC block filter, RX Gain (LNA, DVGA), TX power, FSK deviation freq, modulation (2/4FSK, GFSK, MSK, ASK/OOK)
- Supports on-air baud rates from 600bps to 500kbps
- Set number of preamble bytes
- Set function of CC2500's GPIO pins
- Optional address filtering
- Options for increasing transmission robustness: Data whitening, Manchester encoding, FEC, syncword, CRC calculation/checking
- Packet radio options: arbitrary payload lengths (1..255), fixed or variable-length payloads
- Supports appending optional packet reception statistics to packet payload (RX role)
- Supports setting frequency by channel number (0..255), and modifiable channel spacing
- RSSI measurement
- FIFO: Read RX, TX states, flush
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
| 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 | Runtime issues |
| P2 | SPIN2 | FlexSpin (6.9.4) | Native/PASM2 | OK |
(other versions or toolchains not listed are not supported, and may or may not work)
- Frequency units in carrierfreq() is non-standard (kHz) due to overflowing spin's variable size limit of s32
