如果身边没有电脑或者显示器，但还是想学习或者玩一下树莓派，那么仅仅需要一台智能手机和一个树莓派就够了。本文教大家如何在手机上以完整显示方式运行Raspberry Pi。
/boot/config.txt文件来给树莓派添加一个硬件的开关，如果想了解其中的原理，可以参考该文章。树莓派电源指示灯和状态指示灯的控制，官方文档中是这么说的：即可以通过关闭act_led_trigge...阅读全文act_led_trigger Choose which activity the LED tracks.Use "heartbeat" for a nice load indicator.(default "mmc")act_led_activelow Set to "on" to invert the sense of the LED(default "off")N.B. For Pi 3B, 3B+, 3A+ and 4B, use the act-ledoverlay.act_led_gpio Set which GPIO to use for the activity LED(in case you want to connect it to an externaldevice)(default "16" on a non-Plus board, "47" on aPlus or Pi 2)N.B. For Pi 3B, 3B+, 3A+ and 4B, use the act-ledoverlaypwr_led_triggerpwr_led_activelowpwr_led_gpioAs for act_led_*, but using the PWR LED.Not available on Model A/B boards.
