esp32经常出现
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
14:48:52.130 -> configsip: 0, SPIWP:0xee
14:48:52.227 -> clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

14:48:52.227 -> entry 0x400805e4

运行TFT_eSPI的示例程序没问题。运行LVGL示例程序经常出问题。有时没法启动。报错：

问题找到。将lv_cnf.h中的 *You will see an error log message if there wasn't enough buffers. */
#define LV_MEM_BUF_MAX_NUM 64//16 增加及解决。
