DP3265S chip unknown protocol

[emrekz]

Hi everyone,
I used a panel with ICN2038 and I never face any problem while working with it. I have took a panel with DP3265S chip which does not work properly. It using PWM based protocol and I tried different approach which written on datasheet but I can't even get one of the pixel of panel to blink. Could I use it without set the any registers in it ?

DP3265S Datasheet Page Some of the version's language is English, but this not.

Could anyone help to me for understanding this protocol which used in DP3265S ?

Hi
The datasheet of the 3265 is not complete, you can see a data for DP3364/65 that are very similar to 3264, but their datasheets has a more details.
But I'm afraid that the datasheet won't help you launch the panel with this library, for this the code needs to be seriously rewritten

Hello, I want to give some tips for who want to use the panel which have this chip.
If you download your chip datasheet from here and then you can translate it to English (if not work, use google visual search or ChatGPT).
You should follow to;

• Page-21, 11-Instruction Table
• Page-22, 11.4-Methods for Sending Register Signals
• Also, you will need to configuration registers map, but it is not located in DP3265S datasheet you should refer to other chips datasheet (eg. DP3269S datasheet has register map table)

If you could send configuration registers right (default values worked for me), led panel will be turn on.

Does your comment mean you were able to get the panel running with the DP3265s driver and library on the ESP32 controller? Do you have a project with the finished code?

You can see an example of DP3265 panel working on a RP2040-based controller in this project: https://github.com/board707/DMD_STM32

Yes, but with my own code and not actually show what I want. I achieve turn it on and this will probably help to display what I want to.
I have code but it would not help anyone it only sending configuration registers.
Also, I viewed your example, I will try it 👍
