ikalogic-sp1000g 0.1.5

Python bindings for SP1000G Logic Analyzer API

Ikalogic SP1000G Python Bindings

Python bindings for the Ikalogic SP1000G series logic analyzers (SP1018G, SP1054G, SP1108G).

Installation

pip install ikalogic-sp1000g

Quick Start

from ikalogic import sp1000g

# Create API instance
api = sp1000g.SP1000G(sp1000g.Model.SP1054G)

# Find and open device
api.create_device_list()
count = api.get_devices_count()
print(f"Found {count} device(s)")

if count > 0:
    api.device_open_first()
    
    # Get firmware version
    fpga_ver = f"{api.get_fpga_version_major()}.{api.get_fpga_version_minor()}"
    print(f"FPGA version: {fpga_ver}")
    
    api.device_close()

Supported Devices

• SP1018G: 18 channels, 1 GHz sampling
• SP1036G: 36 channels, 1 GHz sampling
• SP1054G: 54 channels, 1 GHz sampling

Basic Usage

Device Management

# Create device list
api.create_device_list()

# Get number of devices
count = api.get_devices_count()

# Get device info
for i in range(count):
    desc = api.get_device_descriptor(i)
    print(f"Device {i}: {desc.serial_number}")

# Open device
api.device_open_first()  # or api.device_open(index)

# Check if open
if api.get_device_open_flag():
    print("Device is open")

# Close device
api.device_close()

Capture Configuration

# Create settings
settings = sp1000g.Settings()
settings.sampling_depth = 1000000      # Total samples
settings.post_trig_depth = 900000      # Samples after trigger
settings.s_clk = 250000000             # 250 MHz sampling

# Set thresholds (mV) - one per channel
settings.thresh_capture_mv = [1650] * 18  # For SP1018G

# Apply settings
api.apply_settings(settings)

Triggering

# Simple trigger
trigger = sp1000g.TriggerDescription()
trigger.type = sp1000g.TriggerType.TRG_RISING
trigger.channel = 0

api.launch_new_capture_simple_trigger(trigger, settings, 0, True, 0, 0, 0)

# Wait for capture
while not api.is_capture_complete():
    time.sleep(0.1)

Reading Data

# Reset transition iterator
api.trs_reset(0)

# Read transitions
while api.trs_is_not_last(0):
    trs = api.trs_get_next(0)
    print(f"Sample {trs.sample_index}: Channel {trs.channel} = {trs.value}")
