spireg_c1101 0.1.0

SPIReg-C1101 provides predefined registers for the CC1101 chip.

SPIReg-C1101

SPIReg-C1101 provides predefined register definitions for the CC1101 transceiver using the SPIReg framework.

Features

• Predefined register mappings for the CC1101 chip.
• Consistent access to register fields using the SPIReg notation.
• Supports both status and configuration registers.
• Ensures type-safe access to individual register fields.

Installation

SPIReg-C1101 uses spireg under the hood.

pip install spireg_c1101

Usage

import spidev
from spireg_c1101.status_register import PARTNUM, VERSION
from spireg_c1101.configuration_register import IOCFG2

# Initialize SPI device
spi = spidev.SpiDev()
spi.open(0, 0)  # Use the appropriate SPI bus and device number
spi.max_speed_hz = 5000000  # Set the SPI clock speed

# Function to read a register
def read_register(register):
    address = register.register | 0x80  # Set the read bit
    response = spi.xfer2([address, 0x00])
    return response[1]

# Function to write a register
def write_register(register):
    address = register.register & 0x7F  # Clear the read bit
    spi.xfer2([address, int(register)])

# Read PARTNUM and VERSION
PARTNUM.value = read_register(PARTNUM.register)
VERSION.value = read_register(VERSION.register)
print(f"Part Number: {PARTNUM.value}")
print(f"Chip Version: {VERSION.value}")

# Read, toggle, and write IOCFG2
IOCFG2.value = read_register(IOCFG2)
IOCFG2.GDO2_INV ^= 1  # Toggle GDO2_INV
write_register(IOCFG2)
print(f"Updated IOCFG2: {IOCFG2.value}")

# Close SPI connection
spi.close()

Registers

See the C1101 documentation for all available registers.

SPI Communication

SPIReg-C1101 only defines register structures. The user is responsible for:

• Implementing SPI communication to read/write register values.
• Integrating with hardware-specific SPI drivers.
• Ensuring correct register access sequences as per the CC1101 datasheet.
