      R128-RGB板,配百问网7寸屏。板子出厂默认代了LVGL例程,接屏幕运行正常。重新编译SDK里面的程序,使用mrtos menuconfig打开LVGL设置(如下图),编译打包烧录。运行后在串口可以看到如下图片中的信息,屏幕不亮,求助解法。

        配置问题,没有配置上PWM

        修改 board/r128s2/devkit_rgb/configs/sys_config.fex

        文件末尾增加

        [pwm7]
        pwm_used        = 1
        pwm_positive    = port:PA22<4><0><2><default>
