    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,...

    Hi, I have a library running (LVGL) with the ST7789_t3 driver on my Teensy 4.1, and I want to use DMA instead of blocking updates. Currently, this is my code. #include <Arduino.h>...

    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...

    Hi! My only I2S DAC board I have available to purchase is a UDA1334 breakout by Adafruit, but it only works when I touch the pins of it, otherwise I just get noise. See the attached videos below.

    This is the SPI version. Itís 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.

    Hello, I have a project where I have a TFT display and I'm using a display library that uses DMA. The display library is very fast, clocking in about 500 FPS, but for some reason if I play a wav (using a high-quality...
