Question about the use of 0x00 and 0x82 in the sendBuffer for setting LCD screen brightness #5

I am currently reviewing the code in your repository and came across a specific code snippet related to setting the brightness of an LCD screen. I have a few questions regarding the usage of 0x00 and 0x82 in the sendBuffer array. Additionally, I would like to know if these values are documented and, if so, which documentation includes them.

Here is the code in question:

https://github.com/dwinhmi/DWIN_DGUS_HMI/blob/ae75ddad21a0110fb5e8b84a58ce1244c7d82d92/src/DWIN.cpp#L74-L79

My specific questions are:

  1. What is the purpose or significance of using 0x00 and 0x82 in the sendBuffer array?
  2. Are these values (0x00 and 0x82) necessary for setting the brightness of the LCD screen? If so, what role do they play?
  3. Is there any documentation that explains the use of these values in the context of setting LCD screen brightness?

I appreciate any clarification you can provide on this matter. Thank you for your time and contribution to the repository.
