Web GUI for RuiDeng USB testers (UM34C, UM24C, UM25C, TC66C)

Simple web GUI written in Python 3. Measurements are stored in sqlite database. Tables and graphs are supported. Live preview and graphing is also available.

Tested on UM34C/UM24C/UM25C.

TC66C also works but this meter is using different mechanism for communication and support for this technology is limited. See requirements for more information.

Based on https://github.com/sebastianha/um34c

Requirements

• UM34C/UM24C/UM25C - meter needs to be connected as serial port
  • Pairing with Windows Settings works fine. After successful installation some serial ports are installed in Device Manager. In my case two. One of them works.
  • On Linux rfcomm can be used
• TC66C - meter is using BLE instead of regular bluetooth so pairing will not work nor RFCOMM will.
  • BLE has very limited support on desktop devices, see used library for supported platforms and versions: https://github.com/hbldh/bleak#features

Installation

Binaries (Win x64 only)

1. Download from releases
2. Extract archive
3. Run executable and web server will be shortly spawned on address http://127.0.0.1:5000
4. Application will be probably blocked by Microsoft SmartScreen. For unblock click More info and Run anyway. I don't have certificate for signing and application does not have any reputation so Microsoft will block by default.

Source code

1. Python 3.4 or newer is required
2. Download from github or git clone https://github.com/kolinger/rd-usb.git
3. Install requirements pip install -r requirements.txt
4. Run with python web.py - this will spawn web server on http://127.0.0.1:5000, port can be changed with first argument: python web.py 5555

On Windows python can be found in Python's installation folder. For example replace python with C:\Python37\python.exe web.py and pip with C:\Python37\python.exe -m pip install -r requirements.txt.

On Linux use python3 and pip3.

Usage

UM34C/UM24C/UM25C

1. Find your serial port (in Device Manager) and fill serial port input.
2. Name your session. For example 'testing some power bank'. This is used to seperate multiple measurements from each other.
3. Select sample rate. Faster sample rate will result in more accurate data but also will create a lot more data. For short measurements use faster sample rate. For longer use slower rate. Choose carefuly.
4. Click Connect
5. Connection will be hopefully successful and you will see measurements in log. Otherwise read log for error messages.

TC66C

1. Make sure your OS is supported and have bluetooth with BLE support (Bluetooth Low Energy)
2. Select TC66C from devices and follow with Setup link.
3. Scan for devices and select your device from list by clicking on it
4. After this you can connect simply by using Connect button. Setup is required only for new/different device.
5. Rest is same as UMxxC but you don't need specify serial port. Bluetooth address is used instead.

Building binaries

1. Install pyinstaller: pip install pyinstaller
2. Generate binary with provided spec file: pyinstaller pyinstaller.spec
3. Binaries will be saved in dist directory
