lv_disp_set_draw_ctx is called. This on its own is not a problem, however once application later invokes lv_disp_set_draw_ctx to redirect drawing calls, it will clear the draw_ctx structure (as is shown in lv_draw_sw_init_ctx) and its value (LV_COLOR_FORMAT_NATIVE) will not be ...
LV_COLOR_DEPTH 选择16 位相较于32 位,内存占用更小,帧率更快,但是色彩总数较少,显示渐变颜色可能会过渡不平滑。 LVGL 新建应用 推荐以 lv_g2d_test 为模板,复制一个新项目: 代码语言:javascript 复制 lichee/rtos-components/thirdparty/littlevgl-8/lv_g2d_test 在Makefile 中,需要包含 sunxifb.mk 公共...
