There is a library for Teensy 4.x that works amazingly with LVGL. It is called ILI9341_T4. Maybe that library can be ported to support ST7789? It has super high performance, VSync and a lot more nice features.

Hello, It is sort of working. I did get a massive FPS boost ( before 68 now 1004! ), but now there's some artifacts. Here is a video showing the artifacts (edit) Is there a way to change the display's SPI clock...

Well, I did some changes and it "works" now, but I get issues running a display and the audio library at the same time. Here is a video of my issue. The code is this.

I connected everything for I2S2. It works better if I leave the MCLK pin disconnected for some reason. When I connect MCLK to SCLK on the DAC, I only get noise no matter what I do. Leaving it disconnected works better,...

I guess it is related, but I don't seem to be having any issues with the mute pin on it. Also, I noticed another thing, while using an SPI-TFT, the audio for some reason gets interrupted for a little (ILI9341). It is...

With some resistor experimentation (I only have 13K ones) I managed to get it almost working, but there is still some noise sometimes which touching the wires completely eliminates. Tomorrow I will go to the electronic...

This is the SPI version. It’s the easiest to use version. My ILI9341 display has an 8-bit parallel interface. And the ILI9342C needs a different driver than the ILI9341

Hi, I have ILI9341 with 8-bit parallel interface, ILI9342C with SPI interface and I have no idea how to get either working. Any ideas? I need quite high performance. Also, sorry to revive old topic.
