BetaFlight统一硬件配置文件研读之feature命令

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
feature RX_SERIAL
feature TELEMETRY
feature OSD

4. 配置情况

# help feature
feature - configure featureslist<->[name]

4.1 feature

# feature
Enabled: RX_SERIAL TELEMETRY LED_STRIP OSD AIRMODE ANTI_GRAVITY

4.2 feature list

# feature list
Available: 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
