GO+树莓派+E53_IA1智慧农业模块

简介

之前手头上有小熊派的开发板，有一个E53_IA1模块，刚好用到树莓派上，使用GO进行控制，实现智慧农业模块功能。

模块介绍

模块电路介绍

按硬件分成五块，其中四块在本次用上了，分别是

1. 补光模块（LED灯）

在这里插入图片描述

2. SHT30(温湿度传感器)

在这里插入图片描述

3. BH1750 光照强度传感器

在这里插入图片描述

4. 电机部分

在这里插入图片描述

5. AT24C02(EEPROM, 本次没用上)

在这里插入图片描述
注意: 除了电机和LED部分，其余都在同一个I2C总线上。

树莓派接线

3. LED部分

package sensorimport ("periph.io/x/conn/v3/gpio""periph.io/x/conn/v3/gpio/gpioreg"
)type LEDSensor struct {pin gpio.PinIOonLevel  gpio.LeveloffLevel gpio.Level
}func NewLEDSensor(pinName string, highIsOn bool) (*LEDSensor, error) {var (sensor = &LEDSensor{}err    error)if err = sensor.init(pinName, highIsOn); nil != err {return nil, err}return sensor, nil
}func (sensor *LEDSensor) init(pinName string, highIsOn bool) (err error) {sensor.pin = gpioreg.ByName(pinName)if nil == sensor.pin {return SensorPinCantFoundError}if highIsOn {sensor.onLevel = gpio.Highsensor.offLevel = gpio.Low} else {sensor.onLevel = gpio.Lowsensor.offLevel = gpio.High}///* 默认关灯 *///if err = sensor.pin.Out(sensor.offLevel); nil != err {//	return//}return
}func (sensor *LEDSensor) GetState() OnOffState {//level := sensor.pin.Read()if sensor.onLevel == sensor.pin.Read() {return OnOffState_ON}return OnOffState_OFF
}func (sensor *LEDSensor) SetState(state OnOffState) (err error) {if OnOffState_ON == state {err = sensor.pin.Out(sensor.onLevel)} else {err = sensor.pin.Out(sensor.offLevel)}return
}func (sensor *LEDSensor) Toggle() (err error) {if sensor.GetState() == OnOffState_ON {err = sensor.SetState(OnOffState_OFF)} else {err = sensor.SetState(OnOffState_ON)}return
}

4. 电机部分

package sensorimport ("fmt""periph.io/x/conn/v3/gpio""periph.io/x/conn/v3/gpio/gpioreg"
)type MotorSensor struct {opt MotorOptionpin gpio.PinOutcurrDutyCycle uint8oned bool

}func (sensor *MotorSensor) Init() error {return nil
}func (sensor *MotorSensor) Destroy() error {return nil
}func (sensor *MotorSensor) Control(isOpen bool) (err error) {if isOpen == sensor.oned {return}err = sensor.control(isOpen)if nil != err {return}sensor.oned = isOpenreturn
}func (sensor *MotorSensor) control(isOpen bool) (err error) {if isOpen {err = sensor.pin.Out(gpio.High)//err = sensor.pin.PWM(gpio.DutyMax/gpio.Duty((100-sensor.currDutyCycle)+1), physic.Hertz*physic.Frequency(sensor.opt.Frequency))} else {err = sensor.pin.Out(gpio.Low)err = sensor.pin.Halt()}return
}func (sensor *MotorSensor) SetDutyCycle(duty uint8) error {//return UnsupportedErrorif 100 < duty {return fmt.Errorf("duty clycle %s", OutOfRangeError.Error())}if sensor.currDutyCycle == duty {return nil}sensor.currDutyCycle = dutyif sensor.oned {if err := sensor.control(sensor.oned); nil != err {return err}}return nil
