class samna.afe2.AfeModel

Bases: pybind11_object

This is the afe part of xyloa v2. XYLO is a programmable, ultra-low power neuromorphic chip for low-dimensional signal processing. XYLO combines the analog front end(AFE) that can efficiently provide pre-processing functionality to input analog signals. XYLO has is highly re-configurable and scalable, which supports feed-forward, recurrent and reservoir and other complex neural network structure. XYLO can be easily combined with various common sensors such as: MEMS microphone , thermal sensor, pressure sensor, vibration sensor, IMU, Gyro, PPG sensor etc.

apply_configuration(self: samna.afe2.AfeModel, arg0: samna.afe2.configuration.AfeConfiguration) → None

Apply a specific samna.afe2.configuration.AfeConfiguration to afe part of xylo.

get_configuration(self: samna.afe2.AfeModel) → samna.afe2.configuration.AfeConfiguration

Get the cached configuration applied last.

get_sink_node(self: samna.afe2.AfeModel) → samna.DeviceSinkNode_afe2_event_input_event

Get the very sink node of afe input events.

get_source_node(self: samna.afe2.AfeModel) → samna.DeviceSourceNode_afe2_event_output_event

write(self: samna.afe2.AfeModel, arg0: List[samna.afe2.event.WriteRegisterValue | samna.afe2.event.ReadRegisterValue | samna.afe2.event.ReadVersion]) → None

samna.afe2.afe_configuration_to_spi_bytes(arg0: samna.afe2.configuration.AfeConfiguration) → bytes

Get the SPI byte stream for the given AFE configuration.

Parameters:

config (afe2.configuration.AfeConfiguration) – The configuration to turn into SPI byte stream.

Returns:

Byte stream to emit on SPI.

samna.afe2.validate_configuration(arg0: samna.afe2.configuration.AfeConfiguration) → Tuple[bool, str]

Validate the given configuration.

Parameters:

config (afe.configuration.AfeConfiguration) – The configuration to validate.

Returns:

A pair of the validation result and the analysis string.
