统一硬件配置文件的设计是一种非常好的设计模式，可以将硬件和软件的工作进行解耦。
1. 源由
cli命令中feature是对BetaFlight飞控软件功能使能开关。至于功能的含义，这里就不展开，随着对系统的深入理解，慢慢就会一点点了解起来的。
比如：TELEMETRY表示电传功能
2. 代码分析
cliFeature
├──> "feature" [print all enabled features]
├──> "feature list" [print all available features]
└──> "feature <feature_name>"
└──> [Find feature]
├──> <cmdline[0] == '-'> featureConfigClear(feature)
└──> <cmdline[0] != '-'> featureConfigSet(feature)
以下是目前BetaFlight飞控系统所支持的features：
// sync this with features_e
static const char * const featureNames[] = {
"RX_PPM", "", "INFLIGHT_ACC_CAL", "RX_SERIAL", "MOTOR_STOP",
"SERVO_TILT", "SOFTSERIAL", "GPS", "",
"RANGEFINDER", "TELEMETRY", "", "3D", "RX_PARALLEL_PWM",
"RX_MSP", "RSSI_ADC", "LED_STRIP", "DISPLAY", "OSD",
"", "CHANNEL_FORWARDING", "TRANSPONDER", "AIRMODE",
"", "", "RX_SPI", "", "ESC_SENSOR", "ANTI_GRAVITY", "", NULL
};
3. 实例分析
# feature
