Issues After Update (Arduino IDE)

cairogomes opened this issue 7 months ago · 11 comments

After the update (1.0.6), even downgrading Lvgl to 8.3.x, the screen displays a partial broken image, a small rectangle in the upper left corner, the rest of the screen is black.

Lilygo T-Display S3 AMOLED.

From my side after after update everything was messed up...
It seems it helps to remove interely lvgl and re-install from arduino library manager;
after that I discovered that now there are 2 lvgl libraries and all my reference has to be updated
Also all custom font files have some problems...

Before update, everything was working perfectly and now everything is really messed up. Let's see if they release a fix.

Yeah ? I'll check it out, can you tell me which example you ran? Currently I use platformio and everything works fine

Answer 4 · 2024-01-31T01:18:33.000Z

Should I use the TFT_eSPI_Sprite example?

Answer 5 · 2024-01-31T01:58:19.000Z

I guess you are using TFT_eSPI_Sprite, because the rotation function was added and the width and height were changed, which caused the original example to run incorrectly. Just swap the width and height.

I had an example (v8.3) customized with my stuff.
After updating old Font files (obtained from Lvgl site) are not working anymore (cache, last part of the file).
This evening I will be more specific

Hi.@mauromorello
You can see my changes from the commit information. I only changed the full-screen refresh to partial refresh. What does this have to do with the font? I look forward to your detailed explanation.

Now this is working for me:

#define LILYGO_TDISPLAY_AMOLED_SERIES

#include "esp_arduino_version.h"
#include <LilyGo_AMOLED.h>
#include <TFT_eSPI.h>

TFT_eSPI tft = TFT_eSPI();
TFT_eSprite spr = TFT_eSprite(&tft);
LilyGo_Class amoled;

#define WIDTH amoled.width()
#define HEIGHT amoled.height()

void setup() {
bool rslt = false;
Serial.begin(115200);
rslt = amoled.begin();
if (!rslt) {
while (1) {
Serial.println("There is a problem with the device!~");
delay(1000);
}
}
spr.createSprite(WIDTH, HEIGHT);
spr.setSwapBytes(1);
}

void loop() {
amoled.pushColors(0, 0, WIDTH, HEIGHT, (uint16_t *)spr.getPointer());
spr.fillSprite(TFT_BLUE);
spr.setTextSize(2);
spr.setTextColor(TFT_WHITE);
spr.setTextWrap(false);
spr.setTextDatum(4);
spr.drawString("Hello World! :)", WIDTH / 2, HEIGHT / 2, 4);
}

You are right, obviously. I think my problem is related to lvgl 9 and my code, not because your update.

I noticed that you still work with 8.3, but when I upgraded Lilygo example arduino IDE update also LVGL to 9
