I have a simple “Hello World” code, which displays some text in the Screen.
This code works on the Arduino IDE, but I get 15 errors from the VSCode compiler.
I’ve already put the libraries in /lib/, took it out. Change Platformio.ini, and several other ways, but can’t get it to compile.
#include <lvgl.h>
#include <TFT_eSPI.h>
#include "lv_conf.h"
/*Change to your screen resolution*/
static const uint16_t screenWidth = 240;
static const uint16_t screenHeight = 240;
static lv_disp_draw_buf_t draw_buf;
static lv_color_t buf[ screenWidth * screenHeight / 10 ];
TFT_eSPI tft = TFT_eSPI(screenWidth, screenHeight); /* TFT instance */
#if LV_USE_LOG != 0
/* Serial debugging */
void my_print(const char * buf)
{
Serial.printf(buf);
Serial.flush();
}
#endif
/* Display flushing */
void my_disp_flush( lv_disp_drv_t *disp_drv, 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 );
tft.startWrite();
tft.setAddrWindow( area->x1, area->y1, w, h );
tft.pushColors( ( uint16_t * )&color_p->full, w * h, true );
tft.endWrite();
lv_disp_flush_ready( disp_drv );
}
void setup()
{
Serial.begin( 115200 ); /* prepare for possible serial debug */
String LVGL_Arduino = "Hello Arduino! ";
LVGL_Arduino += String('V') + lv_version_major() + "." + lv_version_minor() + "." + lv_version_patch();
Serial.println( LVGL_Arduino );
Serial.println( "I am LVGL_Arduino" );
lv_init();
#if LV_USE_LOG != 0

lv_disp_draw_buf_init( &draw_buf, buf, NULL, screenWidth * screenHeight / 10 );
static lv_disp_drv_t disp_drv;
lv_disp_drv_init( &disp_drv );
disp_drv.hor_res = screenWidth;
disp_drv.ver_res = screenHeight;

//lv_demo_widgets();

Serial.println( "Setup done" );
}
void loop()
{
lv_timer_handler(); /* let the GUI do its work */
delay( 5 );
}
Seems the compiler can’t find any of the libraries, but I can click with the right mouse button in any of the Includes, and navigate to the definition.
I’ve already tried even hardcoding the libraries (removing it from platformio.ini file, adding the libraries to /lib/ and changing the C/C++ configuration to add my entire workspace to the library path).
Nothing works
