mmwave.dataloader.adc¶

class mmwave.dataloader.adc.DCA1000(static_ip='192.168.33.30', adc_ip='192.168.33.180', data_port=4098, config_port=4096)¶

Software interface to the DCA1000 EVM board via ethernet.

static_ip¶

IP to receive data from the FPGA

Type:	str

adc_ip¶

IP to send configuration commands to the FPGA

Type:	str

data_port¶

Port that the FPGA is using to send data

Type:	int

config_port¶

Port that the FPGA is using to read configuration commands from

Type:	int

General steps are as follows:

Examples

>>> dca = DCA1000()
>>> adc_data = dca.read(timeout=.1)
>>> frame = dca.organize(adc_data, 128, 4, 256)

close()¶

Closes the sockets that are used for receiving and sending data

Returns:	None

configure()¶

Initializes and connects to the FPGA

Returns:	None

static organize(raw_frame, num_chirps, num_rx, num_samples)¶

Reorganizes raw ADC data into a full frame

Parameters:	raw_frame (ndarray) – Data to format num_chirps – Number of chirps included in the frame num_rx – Number of receivers used in the frame num_samples – Number of ADC samples included in each chirp
Returns:	Reformatted frame of raw data of shape (num_chirps, num_rx, num_samples)
Return type:	ndarray

read(timeout=1)¶

Read in a single packet via UDP

Parameters:	timeout (float) – Time to wait for packet before moving on
Returns:	Full frame as array if successful, else None
