class rofunc.devices.emg.src.pytrigno.TrignoEMG(channel_range, samples_per_read, units='V', host='localhost', cmd_port=50040, data_port=50041, timeout=10)[source]#

Bases: rofunc.devices.emg.src.pytrigno._BaseTrignoDaq

Delsys Trigno wireless EMG system EMG data.

Requires the Trigno Control Utility to be running.

channel_rangetuple with 2 ints: Sensor channels to use, e.g. (lowchan, highchan) obtains data from channels lowchan through highchan. Each sensor has a single EMG channel.
samples_per_readint: Number of samples per channel to read in each read operation.
units{‘V’, ‘mV’, ‘normalized’}, optional: Units in which to return data. If ‘V’, the data is returned in its un-scaled form (volts). If ‘mV’, the data is scaled to millivolt level. If ‘normalized’, the data is scaled by its maximum level so that its range is [-1, 1].
hoststr, optional: IP address the TCU server is running on. By default, the device is assumed to be attached to the local machine.
cmd_portint, optional: Port of TCU command messages.
data_portint, optional: Port of TCU EMG data access. By default, 50041 is used, but it is configurable through the TCU graphical user interface.
timeoutfloat, optional: Number of seconds before socket returns a timeout exception.

rateint: Sampling rate in Hz.
scalerfloat: Multiplicative scaling factor to convert the signals to the desired units.

Initialization

set_channel_range(channel_range)[source]#

Sets the number of channels to read from the device.

channel_rangetuple: Sensor channels to use (lowchan, highchan).

read()[source]#

Request a sample of data from the device.

This is a blocking method, meaning it returns only once the requested number of samples are available.

datandarray, shape=(num_channels, num_samples): Data read from the device. Each channel is a row and each column is a point in time.
