Description
Crooked image LVGL 8.3.11
What MCU/Processor/Board and compiler are you using?
STM32H723VGT6
What do you want to achieve?
Correct work
What have you tried so far?
I tried buffers of different sizes.
Code to reproduce
Add the relevant code snippets here.
The code block(s) should be between ```c and ``` tags:
/*You code here*/
void lvgl_init()
{
static lv_disp_draw_buf_t draw_buf;
static uint16_t buf1[LCD_WIDTH * 10]; /*Declare a buffer for 1/10 screen size*/
lv_init();
lv_disp_draw_buf_init(&draw_buf, buf1, NULL, LCD_WIDTH * 10); /*Initialize the display buffer.*/
static lv_disp_drv_t disp_drv; /*Descriptor of a display driver*/
lv_disp_drv_init(&disp_drv); /*Basic initialization*/
disp_drv.flush_cb = tft_lvgl_disp_flush; /*Set your driver function*/
disp_drv.draw_buf = &draw_buf; /*Assign the buffer to the display*/
disp_drv.hor_res = lcd_get_width(); /*Set the horizontal resolution of the display*/
disp_drv.ver_res = lcd_get_height(); /*Set the vertical resolution of the display*/
lv_disp_drv_register(&disp_drv); /*Finally register the driver*/
}
