下面是一个简单的示例,用于在两个显示设备上显示不同的屏幕: voiddisp1_refresh_cb(lv_disp_drv_t*disp_drv,constlv_area_t*area,lv_color_t*color_p){// refresh display 1}voiddisp2_refresh_cb(lv_disp_drv_t*disp_drv,constlv_area_t*area,lv_color_t*color_p){// refresh display 2}voidmai...
其中,lv_port_disp_init函数里主要要选择一种写缓存的方式及设置显示分辨。我们选择第一种写缓存的方式,修改后的函数如: // 微信公众号:嵌入式大杂烩voidlv_port_disp_init(void){/*---* Initialize your display* ---*/disp_init();/*---* Create a buffer for drawing*---*//* LVGL requ...

6、找到disp_flush()函数,并根据你的硬件实际情况,将其改写。比如这是使用GLCD_DrawBitmap进行实现的参考代码: 代码语言:javascript 复制 /*Flush the content of the internal buffer the specific area on the display *You can use DMA or any hardware acceleration to do this operation in the background ...
