content: Hello,Does anyone have access to the datasheet for FM6363C and FM6565C chips.Chips are used in newest version of P1.25 LED matrix 256x128 pixels available on aliexpress.I tried to contact the manufacturer (https://www.superchip.cn) but the only contact is through a form on the website.But all attempts to fill it out and send it end in failure (probably because the phone number is outside of China).Maybe someone from China will try to contact them.BR JarekC

content: Unfortunately, the documentation available on LCSC/JLCPCB is only a shortened catalog cardthat does not contain information about configuration registers, their addresses or access methods.It is useless in the case of the need to write your own driver for this chip.BR JarekC

content: Led panel drivers are often clones of other devices, maybe Macroblock, so maybe worth comparing.7

content: If all else fails, get the controller for these panels and reverse engineer it. Probably ot too complex

content: Unfortunately, the chips can differ a lot from each other (these are S-PWM chips).I am waiting for the panel to be delivered.I am considering revese engenerring using the program LEDVision and the Colorlight 5A-75B control card.

content: I received the package with the display, it looks very good. Unfortunately I still haven't managed to get the documentation for the FM6565C chips.

I also found something.Finding datasheets for specific LED drivers like the FM6363C and FM6565C can be challenging, especially with limited manufacturer info. You might try exploring various ICs suppliers that specialize in integrated circuits—some platforms categorize LED drivers under generalICssections, which could lead to compatible documentation or equivalents worth checking out.

content: Unfortunately still no success.LCSC technical support responded to my request but they did not get anything more than what is available on their website.I found the contact for FM superchip after-sales support (chenliyu@superchip.cn) but no response to my emails.There is still the option of reverse engineering.Does anyone have experience with LED walls based on Novastar or Colorlight cards?I would like to build the simplest configuration:PC with 1GB ethernet port ->>>> Receiver card (with HUB320 ports) ->>>> LED matrix module (FM6565C chips).Colorlight system:LEDvision 8.5 (latest version with Net Card mode, work without sender card)E320 receiver cardFor now I only have Colorlight 5A-75B V8.0 receiver card with HUB75E ports.Is it possible to convert two HUB75E ports to one HUB320 port?
