Usage Example

from usb_iss import UsbIss, defs

# Configure I2C mode

iss = UsbIss()"COM3")

# Write and read back some data
# NOTE: I2C methods use 7-bit device addresses (0x00 - 0x7F)

iss.i2c.write(0x62, 0, [0, 1, 2]);
data =, 0, 3)

# [0, 1, 2]


pip install usb-iss

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
