先根据自己的习惯,创建基础的单片机工程,然后在APP业务层和DRIVER驱动层之间加上MIDDLEWARE层,在这一层中加入lvgl。 另外,这里还有句话: 所以如果用到lvgl,尽可能使用裸机开发。 基于LVGL版本V8.2。 注意 移植lvgl之前应先保证LCD和定时器的驱动是正常的。
an ESP API like lv_esp32_spi_init(&drv, &spi_cfg) where spi_cfg is something like: typedef struct { int spi_instance; //e.g. HSPI int clk_io; int mosi_io; int miso_io; int cs_io; int clk_speed; //E.g. 20 MHz }lv_esp32_spi_cfg_t It initializes a driver with the ...
一、OLED介绍:我们的屏幕采用的是128*64的分辨率的,驱动ic应该是SSD1306,这个刚好支持129*64的,但是就是单色屏,用的是spi接口。/* ☐ 首先初始化io口:☐ csi_ ...
