Deepcool LD Series Digital support for non-Windows OS

using HIDAPI

should works on Linux, FreeBSD and other places where hidapi is supported

Note

the current state of this repo is intended to be more of a reference implementation for using the cooler display outside Windows, and not suitable for use as-is (unless you somehow have a FreeBSD machine with amdtemp(4) compatible CPU and the LD series cooler attached to it, that is)
also, there's no plan to package this into a ready to use service currently

requirements

python3, hidapi python bindings, and system's hidapi library

additionally, psutil for conveniences in gathering sensors data, but that's not the main point

device usage

the main piece is in ld_series.py

initialization

write the two packets in ld_series.INIT_SEQUENCE to the device, note that the packets are already complete and ready to be used in hidapi device.write() command

make and send the report data

use ld_series.make_report(power, temp, usage, use_fahrenheit=False) to generate a report packet from supplied values, then write them to the device using hidapi device.write() command

supported values:

• power (uint16, should be watts)
• temperature (float32, in degC, or degF with use_fahrenheit=True)
  • despite it taking float32 shaped value, it doesn't seems handle/display negative temps properly, probably needs more investigation
• usage (uint8, cpu percent, should be between 0-100)

example

quick example:

import hidapi
import ld_series

dev = hidapi.device()
dev.open(ld_series.VID, ld_series.PID)

# init sequence
for packet in ld_series.INIT_SEQUENCE:
    dev.write(packet)

# send some data
report = ld_series.make_report(power=0, temp=30, usage=7)
dev.write(report)

# close device when exit
dev.close()
