Python binding to Rust uem_reader crate

This is a Python binding for MicroEM reader support crate in Rust.

Note on using libusb

On Linux you need to add write permissions to the device you want to use, e.g.:

sudo chmod o+w /dev/bus/usb/002/008

To work with Windows you need to install libusb driver for a reader.

Usage

You can find module sources on GitHub.

import uem_reader_py
rdrs = uem_reader_py.find_usb_readers()
assert len(rdrs) > 0
rdrs[0].open()
print(rdrs[0].send([0x64]))  # Get Version
print(rdrs[0].send([0x22]))  # Get Serial
rdrs[0].send([0x05, 0x03])  # Beep 3 times
rdrs[0].close()
