Riden

A python library for Riden RD power supplies
This library is based on Baldanos/rd6006

Custom Firmware

It appears Ruiden has changed something in recent stock firmware versions that breaks modbus communication.
I would recommend using UniSoft's custom firmware which is based on older stock firmware, but adds many, many new features.
This is the reference document for the Custom Firmware, it includes instructions on where to download and how to flash it.
You could also try downloading older stock firmware and flashing it, I don't know where to get those firmware versions.

Installation

Requirements:

• Firmware UniSoft's custom firmware
• Python 3.7 or later

$ pip install --user git+https://github.com/shaybox/riden.git

Adding to an existing poetry project:

$ poetry add git+https://github.com/shaybox/riden.git

Usage

There's a script to print out basic information about the power supply:

$ riden --port=/dev/ttyUSB0 --baudrate 115200

from riden import Riden

# These are the default values for port, baudrate, and address
r = Riden(port="/dev/ttyUSB0", baudrate=115200, address=1)

# Getters and Setters are available
print(r.get_v_set())
print(r.get_i_set())
r.set_v_set(4.20)
r.set_i_set(0.50)

# Mass polling is available as well
# This reduces the number of reads to the device
r.update()
print(r.v_set)
print(r.i_set)

There's also a Bootloader class that can be used to update the firmware.
This is based on tjko/riden-flashrool

$ riden --port=/dev/ttyUSB0 --baudrate 115200 --firmware path/to/firmware.bin

from riden import Bootloader
# Address is only required to reboot the device into bootloader mode via modbus
# These values are the defaults
Bootloader(port="/dev/ttyUSB0", baudrate=115200, address=1).flash("path/to/firmware.bin")
