My Issue

I don't know how to config for this panel. My code following.

My test code

Below that example code, i don't change anything.

Hi Please provide more info about your setup and connections.

1. The panel should use a third type of chip - it would be better if you could provide its ID for me.
2. What the exact library version you use? "dev-V2" is not a version, the version number looks like 0.9.5 or 1.1.4
3. Please show your test code

1. Sorry, i don't know what is a third type of chip. 2 & 3. I updated.

Thank you Note that in COLOR_4BITS mode the R G B & CLK pins must be either PA0- PA6 or PB0-PB6 without gaps in numbers. In contrast, your pin set does not contain pins PB2 and PB4, and the CLK is selected in the upper half of the port.

To use these pins, you need to change the color mode to COLOR_4BITS_Packed. Than run the test dmd_rgb_pattern_test.ino

Thanks!! I tried, but same result.

DMD_RGB_FM6363 <5,160,80,40,0, COLOR_4BITS_Packed> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

[board707]

Please explain what the result you got?

[tieutuanbao]

Sorry, nothing happened on my panel.

Hi Honesty speaking, I don't have much ideas about the issue. I didn't found any serious errors in your code. Your board and selected pins are not tested before, but I see nothing wrong in them.

Could you test working with panel, using the pins from the examples?
