Python library to support Point Of Sale displays

Project description

Hardware Customer Display

Python library for supporting Customer Point Of Sale Display.

It should support most serial and USB-serial LCD displays out-of-the-box or with inheritance of a few functions.

It has been tested with:

For Epson OCD300, change pywebdriver/config/config.ini :

` [display_driver] device_name=/dev/ttyACM0 `

For Bixolon devices connected via USB, for kernel >= 3.12, you have to create a file /etc/udev/rules.d/99-pyposdisplay.rules with the following content:

` ACTION=="add", ATTRS{idVendor}=="1504", ATTRS{idProduct}=="0011", RUN+="/sbin/modprobe ftdi_sio", RUN+="/bin/sh -c 'echo 1504 0011 > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'" ACTION=="add", ATTRS{idVendor}=="1504", ATTRS{idProduct}=="008c", RUN+="/sbin/modprobe -q ftdi_sio" RUN+="/bin/sh -c 'echo 1504 008c > /sys/bus/usb-serial/drivers/ftdi_sio/new_id'" ` (Source : http://www.leniwiec.org/en/2014/06/25/ubuntu-14-04lts-how-to-pass-id-vendor-and-id-product-to-ftdi_sio-driver/)

For kernel < 3.12 and bixolon display please read this: http://techtuxwords.blogspot.fr/2012/12/linux-and-bixolon-bcd-1100.html

This library has been inspired by the work carried out during a POS code sprint at Akretion France from July 7th to July 10th 2014.
