Tab5, LVGL, trying to get touch working

HappyUser

Solved: somehow commented the lv_tick_inc(5); in the main loop.

Hi, I m trying to get touch working together with lvgl 8.3. I believe the code is not working. Any suggestions? ```

#include <arduino.h>
#include <M5GFX.h>
#include <M5Unified.h>
#include <WiFi.h>
#include <WiFiClient.h>
#include <esp_now.h>
#include <lvgl.h>
#include <M5GFX.h>

M5GFX display;

#define LVGL_LCD_BUF_SIZE (Screen_Width * Screen_Height)

// lvgl variables
static lv_disp_drv_t disp_drv;
static lv_disp_draw_buf_t draw_buf;
static lv_color_t *buf;

// UI objects
lv_obj_t * screen;

void lv_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);
//M5.Display.pushImageDMA(area->x1, area->y1, w, h, (uint16_t *)&color_p->full);
display.pushImageDMA(area->x1, area->y1, w, h, (uint16_t *)&color_p->full);
lv_disp_flush_ready(disp);
}

// touch callback
static void lv_indev_read(lv_indev_drv_t *indev_driver, lv_indev_data_t *data)
{
lgfx::touch_point_t tp[3];
// uint8_t touchpad = M5.Display.getTouchRaw(tp,3);
uint8_t touchpad = display.getTouchRaw(tp,3);
if (touchpad > 0)
{
data->state = LV_INDEV_STATE_PR;
data->point.x = tp[0].x;
data->point.y = tp[0].y;
Serial.printf("X: %d Y: %d\n", tp[0].x, tp[0].y); //for testing
}
else
{
data->state = LV_INDEV_STATE_REL;
}
}

void setup() {
//auto cfg = M5.config();
//M5.begin(cfg);
//M5.Display.startWrite();
//M5.begin();
Serial.begin(115200);
delay(300);

Serial.println("And we have started");

display.init();
lv_init();

buf = (lv_color_t *)heap_caps_malloc(sizeof(lv_color_t) * LVGL_LCD_BUF_SIZE, 
    MALLOC_CAP_SPIRAM | MALLOC_CAP_8BIT);
lv_disp_draw_buf_init(&draw_buf, buf, NULL, LVGL_LCD_BUF_SIZE);


// set up display driver
lv_disp_drv_init(&disp_drv);

disp_drv.hor_res = Screen_Width;
disp_drv.ver_res = Screen_Height;


disp_drv.flush_cb = lv_disp_flush;
disp_drv.draw_buf = &draw_buf;
disp_drv.sw_rotate = 1;  
disp_drv.rotated = LV_DISP_ROT_90; 
lv_disp_drv_register(&disp_drv);

// initialise touch
static lv_indev_drv_t indev_drv;
lv_indev_drv_init(&indev_drv);
indev_drv.type = LV_INDEV_TYPE_POINTER;
indev_drv.read_cb = lv_indev_read;
lv_indev_drv_register(&indev_drv);

}

void loop() {
lv_timer_handler();
delay(5);
