Logic

class Nets.Logic

Signals that can be insepected with a logic analyzer

start_capture()

Start capturing logic of net's waveform.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Logic,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.start_capture()

stop_capture()

Stop capturing logic of net's waveform.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Logic,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.stop_capture()

start_single_capture()

Start capture logic of net's waveform, but then stop after first capture.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.start_single_capture()

trigger_force()

Force a trigger to capture the net's waveform.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.trigger_force()

size_large()

Set the size of the waveform on logic analyzer screen to largest.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.size_large()

size_medium()

Set the size of the waveform on logic analyzer screen to medium.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.size_medium()

size_small()

Set the size of the waveform on logic analyzer screen to small.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.size_small()

set_signal_threshold(voltage)

Set minimum signal voltage threshold for logic analyzer to capture in volts.

from lager import Net, NetType

sda_net = Net.get('I2C.SDA',
            type=NetType.Analog,
            setup_function=setup_net,
            teardown_function=teardown_net)
sda_net.enable()
sda_net.set_signal_threshold(1.5)

Parameters:

voltage (float) -- threshold voltage
