Compilation and runtime problems ..

miracle · January 2024

Hello all,

trying to get some basic code compiled on a Wizee-ESP32 WZ8048C050. Unfortunately the example provided here https://www.elecrow.com/wiki/index.php?title=File:LvglWidgets-5.0-helloworld.zip doesn't compile. It seems that the GFX Library for Arduino needs to be a much older Version like 1.3.0.

After compiling successfully there's now a runtime error stating:

-> E (19) lcd_panel.rgb: esp_lcd_new_rgb_panel(151): no mem for frame buffer
-> ESP_ERROR_CHECK failed: esp_err_t 0x101 (ESP_ERR_NO_MEM) at 0x4037abf4
-> file: "z:\nextcloud\arduino\libraries\GFX_Library_for_Arduino\src\databus\Arduino_ESP32RGBPanel.cpp" line 118
-> func: uint16_t* Arduino_ESP32RGBPanel::getFrameBuffer(int16_t, int16_t)
-> expression: esp_lcd_new_rgb_panel(_panel_config, &_panel_handle)

and the display is caught in a reboot loop. Is there any suggestions or a fix for this?

Hello @miracle ,

Please modify the display configuration according to

ESP32 HMI Demo Code Updated - compatible with new version of esp32 package

Elecrow Dec 1, 2023

When we first edited the demo code, we based it on the 2.0.3 version of the esp32 package, which resulted in compilation errors for many users who installed the new version of esp32. To solve this problem, we updated the esp32 demo code. The updated content is as follows:

For 5-inch esp32 screen:

Modify the following code

https://forum.elecrow.com/uploads/111/5FZCYAHAOJCQ.png

into

Arduino_RPi_DPI_RGBPanel *lcd = new Arduino_RPi_DPI_RGBPanel(
  bus,
  800 /* width */, 0 /* hsync_polarity */, 210 /* hsync_front_porch */, 4 /* hsync_pulse_width */, 43 /* hsync_back_porch */,
  480 /* height */, 0 /* vsync_polarity */, 22 /* vsync_front_porch */, 4 /* vsync_pulse_width */, 12 /* vsync_back_porch */,
  1 /* pclk_active_neg */, 16000000 /* prefer_speed */, true /* auto_flush */);
#endif /* !defined(DISPLAY_DEV_KIT) */

For 7-inch esp32 screen:

Step 1: Download the LovyanGFX library

https://forum.elecrow.com/uploads/893/XTEWU22K7BIT.png

Step 2: Modify the code of HMI-7.0

Add the following code:

#define LGFX_USE_V1
#include <LovyanGFX.hpp>
#include <lgfx/v1/platforms/esp32s3/Panel_RGB.hpp>
#include <lgfx/v1/platforms/esp32s3/Bus_RGB.hpp>

  // Constructor for the LGFX class.

    // Configure the RGB bus.
    {
      auto cfg = _bus_instance.config();
      cfg.panel = &_panel_instance;


      // Configure data pins.
      cfg.pin_d0  = GPIO_NUM_15; // B0

      cfg.vsync_back_porch  = 13;


      // Configure polarity for clock and data transmission.
      cfg.pclk_active_neg   = 1;
      cfg.de_idle_high      = 0;
      cfg.pclk_idle_high    = 0;


      // Apply configuration to the RGB bus instance.
      _bus_instance.config(cfg);
    }


    // Configure the panel.
    {
      auto cfg = _panel_instance.config();
      cfg.memory_width  = 800;
      cfg.memory_height = 480;
      cfg.panel_width   = 800;
      cfg.panel_height  = 480;

      cfg.offset_y      = 0;


      // Apply configuration to the panel instance.
      _panel_instance.config(cfg);
    }


    // Set the RGB bus and panel instances.
    _panel_instance.setBus(&_bus_instance);
    setPanel(&_panel_instance);
  }
};
LGFX lcd;

and delete the following code:

#include <Arduino_GFX_Library.h>
#define TFT_BL 2

modify the following code

/* Display flushing */
void my_disp_flush(lv_disp_drv_t *disp, const lv_area_t *area, lv_color_t *color_p)
{
  uint32_t w = (area->x2 - area->x1 + 1);
  uint32_t h = (area->y2 - area->y1 + 1);


#if (LV_COLOR_16_SWAP != 0)
  lcd->draw16bitBeRGBBitmap(area->x1, area->y1, (uint16_t *)&color_p->full, w, h);
#else
  lcd->draw16bitRGBBitmap(area->x1, area->y1, (uint16_t *)&color_p->full, w, h);
#endif


  lv_disp_flush_ready(disp);
}

into

/* Display flushing */
void my_disp_flush(lv_disp_drv_t *disp, const lv_area_t *area, lv_color_t *color_p)
{


  uint32_t w = (area->x2 - area->x1 + 1);
  uint32_t h = (area->y2 - area->y1 + 1);
  


  //lcd.fillScreen(TFT_WHITE);
#if (LV_COLOR_16_SWAP != 0)
 lcd.pushImageDMA(area->x1, area->y1, w, h,(lgfx::rgb565_t*)&color_p->full);
#else
  lcd.pushImageDMA(area->x1, area->y1, w, h,(lgfx::rgb565_t*)&color_p->full);//
#endif


  lv_disp_flush_ready(disp);


}

Step 3: Use the quick search function(Ctrl+F) to replace lcd-> in the code with lcd.

the problem unfortunately persist.

In its core (no memory at runtime) it's somehow related to the board chosen in Arduino IDE when uploading to the device. "ESP32S3 Dev Module" with no PSRAM doesn't work. Other board give other runtime errors. The setup in PlatformIO with huge_app.csv makes me wonder how to do this with Arduino IDE?

forgot to mention that Menu -> Tools -> Partition Scheme: -> "Huge App (3MB No OTA/1MB SPIFFS" doesn't do the trick.
