ESP32-8048S070/ESP32-8048S050 origin dislocation

[smily77]

I have a ESP32-8048S070 which shows a strange origin dislocation. With draw and and print (TextSize(1)) the origin appears somewhere in the middle of the screen. Funny is that the origin for the print (but only for the print) works correct with textSize(2). I use ArduinoIDE 1.8.19 / Arduino GFX 1.4.2 / ESP 2.0.14 (ESP2.0.3 doesn't compile in my IDE with GFX 1.4.2??) The program: ``#include

define GFX_BL 2

Arduino_ESP32RGBPanel rgbpanel = new Arduino_ESP32RGBPanel( 41 / DE /, 40 / VSYNC /, 39 / HSYNC /, 42 / PCLK /, 14 / R0 /, 21 / R1 /, 47 / R2 /, 48 / R3 /, 45 / R4 /, 9 / G0 /, 46 / G1 /, 3 / G2 /, 8 / G3 /, 16 / G4 /, 1 / G5 /, 15 / B0 /, 7 / B1 /, 6 / B2 /, 5 / B3 /, 4 / B4 /, 0 / hsync_polarity /, 210 / hsync_front_porch /, 30 / hsync_pulse_width /, 16 / hsync_back_porch /, 0 / vsync_polarity /, 22 / vsync_front_porch /, 13 / vsync_pulse_width /, 10 / vsync_back_porch /, 1 / pclk_active_neg /, 16000000 / prefer_speed /); Arduino_RGB_Display gfx = new Arduino_RGB_Display( 800/ width /, 480/ height /, rgbpanel, 0 / rotation /, true / auto_flush /);

void setup() { pinMode(GFX_BL, OUTPUT); digitalWrite(GFX_BL, HIGH);

gfx->begin(); gfx->setRotation(0); gfx->fillScreen(BLACK); gfx->drawLine(0, 0, 400, 400, YELLOW); gfx -> setCursor(0,0); gfx->setTextSize(1); for(int i=0;i<26;i++) { gfx-> println(i); } gfx -> setCursor(0,0); gfx->setTextSize(2); for(int i=0;i<26;i++) { gfx-> print(" "); gfx-> println(i); } }

void loop() { delay(100); }`` Both, the ESP32-8048S070 & ESP32-8048S050 (5 inch version) show the same error but the displaced isn't exactly at the same place
BTW: For the ESP32-8048S070&50 the line 1 / pclk_active_neg /, 16000000 / prefer_speed /); is required but not mentioned in the Wiki (please update)

Same issue here with v. 1.4.2 of the library, using a ESP32-8048S050 display with an ESP32S3 module. Driver is a ST7262.

The origin is somewhere in the upper left quadrant. Negative coordinates are not displayed at all.

For me, though, it doesn't have any impact if that line is there or not.

I might mention that both v 1.4.0 or 1.4.1 of the library cause the ESP to constantly reboot, with the same (minimal) sketch.

I can repeat this with:

1. Elecrow 4.3" RGB 480x272 display
2. Espressif-S3-LCD-EV-Board

I'm trying to run the PDQgraphicstest code using:

• Arduino 2.2.1
• GFX 1.4.2

The graphics origin appears mid way down the screen in the middle of the line. The code bombs, presumably because memory is getting overwritten when it shouldn't. Text appears to be fine.

Thanks

Try lower prefer_speed, in most case it should be 6000000 or 12000000.

[DrTron]

No, lower speed does not change anything.

I have dropped back to using GFX 1.40.

This works for me on the Elecrow 4.3" RGB 480x272 display. ESP32-S3

Please help to test with v1.4.3

1.4.3 works in my case
