ECTweaker

ECTweaker Library for python allows users to read/write and control the EC of laptops, specially MSI!

INSTALLATION

• pip install ectweaker
  • If the above method doesn't work please install in a virtual environment and call it in scripts from the virtual environments only!

Preparing the EC to be read/write friendly

• Disable secure boot
• To check one of the example to use this code properly, visit https://github.com/YoCodingMonster/OpenFreezeCenter-Lite/tree/main and check OpenFreezeCenter-Lite.py file

Updating

• pip install ECTweaker --upgrade

Functions

check()

• This prepare the OS for EC read/write functionality and reboots the system for the first time only.
  • Return Type - int
  • Returns
    • 1 if EC read/write is enabled.
    • 0 if EC read/write is not enabled.
  • Example

  import os
  CHECK = ECT.check()
  if CHECK == 1:
      # your_script_here
  else:
      os.system("shutdown -r +1")
      print("Rebooting system within 1 min!\nPlease save all work before it happens!")
  

write(BYTE ADDRESS, VALUE)

• This will allow you to write any INTEGER value to BYTE ADDRESS.
  • Parameters
    • BYTE ADDRESS - Hex address of the memory where VALUE needs to be written.
    • VALUE - content which needs to be written at BYTE ADDRESS.
  • Example

  import ECTweaker as ECT
  ECT.write(0xd4, 121)
  

read(BYTE ADDRESS, SIZE)

• This will allow you to read INTEGER value from BYTE ADDRESS.
  • Return Type - int
  • Returns - VALUE stored at BYTE ADDRESS fo memory provided.
  • Parameters
    • BYTE ADDRESS - Hex address of the first memory from where VALUE is retrived.
    • SIZE - How many adjacent BYTE ADDRESS stores the complete VALUE.
  • Example

  import ECTweaker as ECT
  VALUE = ECT.read(0xd4, 1)
  

fan_profile(PROFILE, VALUES)

• This allows for MSI laptops with intel CPU to set Fan profiles.

  • Parameters

    • PROFILE - Fan profile which needs to be, considered values are as follows.
      • auto, advanced, cooler booster
    • ONOFF - This is a list of address and values which needs to be set in order to change the fan profile.
      • [[ADDRESS, VALUE ON],[COOLER BOOSTER ADDRESS, VALUE OFF]]
    • ADDRESS - This is the list of addresses for CPU and GPU fan speeds as [[CPU1, CPU2, CPU3, CPU4, CPU5, CPU6, CPU7], [GPU1, GPU2, GPU3, GPU4, GPU5, GPU6, GPU7]]
    • SPEED - This is the list of speed percentages for CPU and GPU fans at set temps as [[CPU1, CPU2, CPU3, CPU4, CPU5, CPU6, CPU7], [GPU1, GPU2, GPU3, GPU4, GPU5, GPU6, GPU7]]

  • Example - Auto is turned on on MSI laptop with 11th gen processor and (Cooler Booster is being turned off as precaution)

  import ECTweaker as ECT
  ECT.fan_profile("auto", ONOFF = [[0xd4, 141], [0x98, 2]], ADDRESS, SPEED)
  

  • Example - Cooler booster is being turned on

  import ECTweaker as ECT
  ECT.fan_profile("auto", ONOFF = [0x98, 130])
  

speed_writer(ADDRESS, SPEED)

• Internal function used by fan_profile(PROFILE, VALUES) function to set the fan speed curve.
  • Parameters
    • ADDRESS - This is the list of addresses for CPU and GPU fan speeds as [[CPU1, CPU2, CPU3, CPU4, CPU5, CPU6, CPU7], [GPU1, GPU2, GPU3, GPU4, GPU5, GPU6, GPU7]]
    • SPEED - This is the list of speed percentages for CPU and GPU fans at set temps as [[CPU1, CPU2, CPU3, CPU4, CPU5, CPU6, CPU7], [GPU1, GPU2, GPU3, GPU4, GPU5, GPU6, GPU7]]
