elitech-datareader 0.9.1

Elitech rc4 data access tool and library.

Description

This software is a data collecting tool, written in python for Temperature data logger RC-4.

Elitech RC-4 is a reasonable data logger.

Enables to use RC-4 on Mac, Linux, Windows.

Requirements

• Python2.7 or Python3.4

• Silicon Labs CP210x USB-UART bridge VCP driver. http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

• pySerial (data access library for serial port)

Setup

1. Install CP210x USB-UART bridge VCP driver. Download and install CP210x driver for your platform. http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

2. install dependencies.

$ python setup.py install

OR pip

$ pip install elitech-datareader

Example(Script)

Example(Python module)

Get device infomation.

import elitech

device = elitech.Device("/dev/tty.SLAB_USBtoUART")
devinfo = device.get_devinfo()
print(devinfo.info)

Get record data

import elitech

device = elitech.Device("/dev/tty.SLAB_USBtoUART")
body = device.get_data()
for elm in body:
    print elm

Update param

device = elitech.Device("/dev/tty.SLAB_USBtoUART")
devinfo = device.get_devinfo()  # get current parameters.

param_put = devinfo.to_param_put()  #convart devinfo to parameter
param_put.rec_interval = datetime.time(0, 0, 10)    # update parameter
param_put.stop_button = elitech.StopButton.ENABLE   # update parameter

param_put_res = device.update(param_put)    # update device
