PYTICC

Python module to interface with Texas Instruments CC1xxx Sub-1Ghz RF transceivers over SPI.

Supported Models

• CC1101

Installation

pip install pyticc

Basic usage

from pyticc.cc1101 import CC1101

cc = CC1101()
cc.sanity_check()
cc.recv_data()

Command Strobes

cc.reset()
cc.power_down()
cc.sidle()
cc.enable_rx()
cc.enable_tx()
cc.wor_on()
cc.sx_off()
cc.calibrate()
cc.flush_rx_fifo()
cc.flush_tx_fifo()

Convenience config methods (get or set)

cc.base_frequency(433)
cc.modulation('OOK')
cc.packet_length('PKT_LEN_VARIABLE')
cc.rx_bandwidth(325000)
cc.sync_word('FAFA')
cc.manchester(1)
cc.whitening(1)

Read and write raw bytes to register

byte = cc.read_byte(0x10)
cc.write_byte('MDMCFG4', byte)

Easy querying and modification of config register attributes

Query by address, or class attribute name.

cc.register_value(0x10)
{
  'CHANBW_E[1:0]': 1,
  'CHANBW_M[1:0]': 3,
  'DRATE_E[3:0]': 8
}

cc.register_write('MDMCFG4', 'CHANBW_M[1:0]', 0x02)

cc.register_write('MDMCFG4', 'CHANBW_M[1:0]', '101')

To Do

• Add more CCxxxx models.
• JSON config dump/load would be cool.
