I’d be glad if someone would share links to aliexpress/ebay or other Chinese shops where you have bought rgb led panels and they work with this library.
This has been my preferred supplier to date.
Shenzhen Coreman Technology Co., Limited
What scan rate are you using? They have 1/2, 1/4 and 1/8 scan.
I’m only buying 1/32.
I’ve been buying from Azerone, they have been very helpful to me, and either sell from amazon, or I send them a message on FB, paypal them money and sell to me direct (from china).
You can friend him/her an FB and/or send DM if you need something not on amazon.
Do they know about this library and what type of panels work with it?
They somewhat know about it since I’ve worked with them on testing panels, but they don’t have the library or a way to test for you.
However, they can check if the panels have FM6126A chips and avoid those, and you can tell them you only want ABCD or ABCDE panels, not AB or ABC.
It’s not a full guarantee, but better than other vendors I’ve worked with.
Also, if the panels are on amazon prime, you can just return them
