This is a fantastic library ... Thanks so much!

It's a great example of how to do software supporting different hardware right - I've looked at dozen's of examples of LVGL libraries and projects people have implemented - this is the only one that keeps support for new boards simple. I not only got my CYD (the esp32-2432s028-v3) working, but also was able to create a new board type for the MKS DLC32 TS35-R display and use it. I've been struggling with this display as there isn't much information about it.

Then star it!

If you have a working new board definition, I can add it to the repository, maybe easier for you also?!

Absolutely - I'll attach it. I wasn't sure if this was in line with your project goals. I would argue that the MKS DLC32 might be of interest to the community of CYD users. You can buy the board, the TS35-R display and 3 TMC2209 stepper drivers shipped on aliexpress for $35 US. It has a nice 5.5 mm barrel connector for power (cheap LED power bricks, also good for automotive, RV, boat applications. Also has I2C, a 12/24 volt PWM, a bunch of 5 volt inputs & a few outputs. Everything on nice connectors & good for solenoid/servo/stepper. A little more expensive than a CYD ... but still pretty reasonable. I actually started with the CYD, but realized that having the power/io made the project actually cheaper/more robust. There is a 2.4 inch version of this screen the TS24-4 that I suspect is pretty similar - I haven't tried it as the price differential is so small - it's only about $4 cheaper. I started by taking the MKS DLC32 fork of grpl32 - trying to extract the relevant code was a nightmare. They've included many of their own header files and their code into the LVGL and TFT-eSPI libraries (I can understand if they need to extend some of the base functions, but at a minimum they should have put some of this code into a new file, or used derived classes or even ifdef's. No guarantees on the board file, but it works for the demo & I've managed to use the SquareLine software to replace the UI files with my own and make everything work (touch screen, display). Thanks!

So the file I sent you only works with the DLC32 & TS35-R screen. I'm wondering if including it is beyond the scope of your project which is oriented toward the Sunton board & clones - you've already got a pretty impressive list of boards just from that. If you start including all the possible combinations of screens, boards & that they may be hooked together in various ways it may not be scalable (this is sort of what platformio/arduino do when they want you to specify a board) - there are a huge number of variations & none of them seem to apply. I'm pretty new to the esp32/platformio/arduino world, so I'm not sure what the solution is. You almost want a web page that would generate a board file & that you could tweak if needed. What I've found frustrating is that I've had to pick some more-or-less appropriate board without knowing what it was really doing. Anyway, feel free to do whatever you think is appropriate - I owe you several hours of my life & possibly my sanity. Kevin

Hi Kevin,

Attachments are probably stripped. Think it's better to make a gist: https://gist.github.com/

Hopefully this is the right way to do it:
