I imported the working Arduino file into PlatformIO with ST7735_t3 Lib and encountered the same error when compiling. I don't know why grrrrr

Thanks. Yes, there's a problem with importing the library. PlatformIO isn't seeming to accept the library from the Arduino Lib folder.

I need help, please. Where is the error?

I'm getting an error message with PlatformIO and VS code. Arduino IDE reporting no errors. But PlatformIO is reporting an error in ST7735_t3.h, line 4970. I don't know where the error is.

Hallo ??

Now. I have Build error!

My ST7796S Touchdisplay Test. tft.updateScreenAsync() doesn't work. tft.updateScreen() work fine. // ST7796S Test #define TFT_MISO 12 #define TFT_MOSI 11 //a12 #define TFT_SCK 13 //a13 #define TFT_DC 8 #define TFT_CS 10 #define...

tft.updateScreenAsync() doesn't work. updateScreen() is work :rolleyes: void redraw_Display(void) { uint16_t color = rand(); tft.fillScreen(color); } void loop() { if (Timer_1 >= 2000) { redraw_Display(); Timer_1 = 0; }...

I found this. FrameBuffer is located in Teensy4.1 Ram2 DMAMEM uint16_t FrameBuffer[320 * 480];

One more question. Can I move the frame buffer to the second RAM area of the Teensy 4.1 or to the 16MB PSRAM expansion?

Thank you. I found the error. It's the duplicate folder names in the Lib. That's always a problem in PlatformIO :confused:

Thanks for your help. I tried to open your library in PlatformIO, but I'm getting errors with ST7796_t3.h.

Hallo I'm using a 3.5-inch Waveshare touchscreen display with an ST7796S chip on my Teensy 4.1. Is there a good library with DMA functionality?

Hallo everybody :) The new DIY synthesizer "Jeannie 2" is in development. Its bigger, it will feature a 3.5-inch touchscreen display and a variety of waldorf encoders, knobs, and buttons for operation. Jeannie 2 will be eight-voice polyphonic...
