Hi,
I already changed the mode. That was not my question. (I also never mentioned to be using the get_configuration() command, maybe we are looking at different versions)
My question was regarding the ltr11.get_next_frame() command.
When I change the mode to CW, I get an error in this command, whereas, for the pulsed mode, it works.
The error I get is: "device could not acquire a complete time domain data frame within the expected time (IFX_ERROR_TIMEOUT)"
So my question was: Since the ltr11.get_next_frame() is not working, is there a different command to save the acquisition data into a variable for the CW mode? (ltr11.get_next_frame() = gets the data contained in the next frame)
To make it easy, I am copying my code below:
from ifxDopplerLTR11 import DopplerLTR11
import numpy as np
print ("Radar SDK Version: " + DopplerLTR11.get_version_full())number_frames = 100
with DopplerLTR11.DopplerLTR11() as ltr11:
# set device config
config_defaults = ltr11.get_config_defaults()
config_defaults.mode=0 # CW = 0 , 1 = Pulsed
samples_frame = config_defaults.num_of_samples # samples per frame
frome = np.zeros((samples_frame,number_frames),dtype = complex) # matrix of zeros to store the values of all samples in all frames
config_defaults.prt=0 # change the sampling rate here 0 = 4KHz, 1 = default = 2KHz
print("Configuration limits", ltr11.get_limits())
ltr11.set_config(config_defaults)
print("Power for current set configuration: ", ltr11.get_active_mode_power(config_defaults))
print("Current Sampling frequency in Hz: ", ltr11.get_sampling_frequency(config_defaults.to_dict()["prt"])) #########
ltr11.start_acquisition()
print("acquisition started")
# A loop for fetching a finite number of frames comes next..
for frame_number in range(number_frames):
frame, metadata = ltr11.get_next_frame()
frame2[:,frame_number] = frame
metadata_dict = metadata.to_dict()
#print("Chip power mode: ", "active mode " if metadata_dict['active'] else "low power mode")
#print("Target Detected" if (metadata_dict['motion'] == 0) else "No Target Detected")
if metadata_dict['motion'] == 0:
print("Approaching " if metadata_dict['direction'] else " Departing")
#print("Average Power Consumption is equal to: ", metadata_dict['avg_power'])
ltr11.stop_acquisition()
If this line -> "config_defaults.mode=0 # CW = 0 , 1 = Pulsed" Is removed, the code works
