I am trying to write lvgl code to run on an ESP32 S3 on the CrowPanel 7" display. I modified one of the official demos. The code is as follows:
/*Using LVGL with Arduino requires some extra steps:
*Be sure to read the docs here: https://docs.lvgl.io/master/integration/framework/arduino.html */
#include <lvgl.h>
/*Set to your screen resolution and rotation*/
#define TFT_HOR_RES 800
#define TFT_VER_RES 480
#define TFT_ROTATION LV_DISPLAY_ROTATION_0
/*LVGL draw into this buffer, 1/10 screen size usually works well. The size is in bytes*/
#define DRAW_BUF_SIZE (TFT_HOR_RES * TFT_VER_RES / 10 * (LV_COLOR_DEPTH / 8))
uint32_t draw_buf[DRAW_BUF_SIZE / 4];
/* LVGL calls it when a rendered image needs to copied to the display*/
void my_disp_flush(lv_display_t *disp, const lv_area_t *area, uint8_t *px_map) {
/*Copy `px map` to the `area`*/
/*For example ("my_..." functions needs to be implemented by you)
uint32_t w = lv_area_get_width(area);
uint32_t h = lv_area_get_height(area);
my_set_window(area->x1, area->y1, w, h);
my_draw_bitmaps(px_map, w * h);
*/
/*Call it to tell LVGL you are ready*/
lv_display_flush_ready(disp);
}
/*Read the touchpad*/
void my_touchpad_read(lv_indev_t *indev, lv_indev_data_t *data) {
/*For example ("my_..." functions needs to be implemented by you)
int32_t x, y;
bool touched = my_get_touch( &x, &y );
if(!touched) {
data->state = LV_INDEV_STATE_RELEASED;
} else {
data->state = LV_INDEV_STATE_PRESSED;
data->point.x = x;
data->point.y = y;
}
*/
}
/*use Arduinos millis() as tick source*/
static uint32_t my_tick(void) {
return millis();
}
void setup() {
String LVGL_Arduino = "Hello Arduino! ";
LVGL_Arduino += String('V') + lv_version_major() + "." + lv_version_minor() + "." + lv_version_patch();
Serial.begin(115200);
Serial.println(LVGL_Arduino);
lv_init();
/*Set a tick source so that LVGL will know how much time elapsed. */
lv_tick_set_cb(my_tick);
lv_display_t *disp;
/*Else create a display yourself*/
disp = lv_display_create(TFT_HOR_RES, TFT_VER_RES);
lv_display_set_flush_cb(disp, my_disp_flush);
lv_display_set_buffers(disp, draw_buf, NULL, sizeof(draw_buf), LV_DISPLAY_RENDER_MODE_PARTIAL);
/*Initialize the (dummy) input device driver*/
lv_indev_t *indev = lv_indev_create();
lv_indev_set_type(indev, LV_INDEV_TYPE_POINTER); /*Touchpad should have POINTER type*/
lv_indev_set_read_cb(indev, my_touchpad_read);
lv_obj_t *label = lv_label_create(lv_screen_active());
lv_label_set_text(label, "Hello Arduino, I'm LVGL!");
lv_obj_align(label, LV_ALIGN_CENTER, 0, 0);
Serial.println("Setup done");
}
void loop() {
lv_timer_handler(); /* let the GUI do its work */
delay(5); /* let this time pass */
}
And here are the error messages I get when I try to compile:
