ST7796S and ESP32-S3-DevKitC-1-N-8R2 seems to cap my sprite maximum size? #3285
Comments
Solved my own issue. I guess I don't quite understand why, but when I set rotation to 1 for landscape, the Height and Width dimensions are now flipped for sprite creation. It's strange, I have to pretend it's oriented portrait when using pushSprite and create sprite. Is that supposed to be that confusing? Why not flip them when you set rotation for consistency? |
Hmmm.. I thought for sure you would not be able to use gpio 35,36,37 when PSRAM is activated. I see that you are using these lines for MISO, MOSI, SCK and it works. Can you please verify that is the case. That opens additional possibilities for me! Thanks |

Ahaaa! Now I see. I've been using the ESP32S3-N16 to gain the extra pins. Looks like a ESP32S3-N16R2 would allow the pins to be used AND get some PSRAM. |
Using This screen from other issue . With the ESP32-S3-DevKitC-1-N-8R2 I have the LCD working, but I can not make a sprite that is full screen. No matter what size sprite I make, it will cap out at around 60% of the 320x480 pixel screen via SPI interface. I do not have the touch chip or SD card wired up, just the LCD pins. I can see the PSRAM enabled, and have the sprite.setAttribute(PSRAM_ENABLE, true);
I CAN see the entire screen when running a demo example with non sprite pushes, but the library seems to be force capping the size of my sprites, EVEN with PSRAM enabled. What am I doing wrong?!

in user setup.h I have #define ST7796_DRIVER
in user select.h i have #include <User_Setups/Setup36_RPi_touch_ST7796.h>
in user_setup_ID36 I have to remove #define RPI_DISPLAY_TYPE or the screen will not boot
#define TFT_MISO 37
#define TFT_MOSI 35
#define TFT_SCLK 36
#define TFT_CS 10 // Chip select control pin
#define TFT_DC 7 // Data Command control pin
#define TFT_RST 6 // Reset pin (could connect to RST pin)
#define TOUCH_CS 2 // Chip select pin (T_CS) of touch screen
tft.setRotation(1); //i've tried 0-3, not the issue
It works but it's some kind of sprite issue. I have worked with smaller screens without PSRAM no problems. I love this library, but I'm currently stumped.
