# Python LT8900 via SPI

This Python module enables a Python to talk to an LT8900 radio attached to an serial peripheral interface (SPI).

## API
### Synopsis

    lt8900_spi.radio(spi_bus, spi_dev, config = None) -> instance
    lt8900_spi.radio.put_register(reg, value) -> value
    lt8900_spi.radio.put_register_bits(reg, bits_dict) -> value
    lt8900_spi.radio.get_register(reg) -> value
    lt8900_spi.radio.get_register_bits(reg, value = None) -> dictionary
    lt8900_spi.radio.configure(config) -> None
    lt8900_spi.radio.initialize() -> boolean
    lt8900_spi.radio.set_channel(channel) -> dictionary
    lt8900_spi.radio.set_syncword(syncword) -> None
    lt8900_spi.radio.fill_fifo(message, include_length = True) -> list
    lt8900_spi.radio.transmit(message, channel = None) -> boolean
    lt8900_spi.radio.multi_transmit(message, channels, retries = 3, delay = 0.1) -> boolean
    lt8900_spi.radio.start_listening(channel) -> boolean
    lt8900_spi.radio.stop_listening() -> boolean
    lt8900_spi.radio.receive(channel = None, wait = False, length = None, wait_time = 0.1) -> list

### instance.get\_register\_bits

Low-level primitive to get a named register with bitfields expanded to names.

### instance.put\_register\_bits
