VoltageControl

It is required to process the text. I will not refuse help :)

Voltagecontrol

Arduino voltage control library.

Sample

The class is template and uses 1 parameter: uint8_t _id = 0 . The first non -compulsory parameter transparently conveys uint8_t value to the caused flasks, which allows you to identify the class when using several copies of the class per one flask. For example PIN reading ADC:

 VoltageControl < A1 > Volt1 ;
VoltageControl < A2 > Volt2 ;
//...
Volt1 . SetRequest ( OnRequestVoltage );
Volt2 . SetRequest ( OnRequestVoltage );
//...
int32_t OnRequestVoltage ( uint8_t id )
{
	return analogRead ( id );
}

Constructor

For convenience, the class has two designers.

` VoltageControl ()`

Class designer without parameters. When used, it is required to convey the settings through Set methods.

• Parameters: No.

 VoltageControl ( request_t callback_req , uint16_t interval_req , response_t callback_res , bool once , uint32_t coefficient , int32_t vmin , int32_t vmax )

Class designer indicating all the settings.

• Parameters: Caus-functioning reading of ADC, ACP reading interval in MS., Caus-functions of the measurement result, a single call flag see the description of SetResponse() , the translating coefficient of the ACP value, the minimum permissible voltage, the maximum permissible voltage.

 int32_t OnRequestVoltage ( uint8_t id )

When the class is necessary to read the value of the ADC, this flask function will be caused. You can perform or integrated method of reading ADC ( analogRead() ), directly work with registers or read an external ADC for any available tire.

• Parameters: transmitted ID.
• Return: raw ADC.

 void OnResponseVoltage ( uint8_t id , int32_t value , int8_t state )

When you need to notify the main program about the changes, this tank-function will be an interchange. You can decide on the branching of the code and fulfill everything you need here.

• Parameters: transmitted ID, current voltage in MV, voltage state, see the description of GetValid() .
• Return: No.

Class methods

 void SetRequest ( request_t callback , uint16_t interval )

The method indicates a tank-function of reading ADC.

• Parameters: Caus-functions, survey interval in the MS.
• Return: No.

 void SetResponse ( response_t callback , bool once = false)

The method indicates a voltage measurement of the voltage measurement result. If once = true , then a call of a flab rate of functions will occur only when the condition is changed (reduced, increased, normal voltage), otherwise the challenge will occur at each measurement of the ADC.

• Parameters: Caus-functions, a single call flag when changing.
• Return: No.

 void SetCoefficient ( uint32_t coefficient )

The method determines the coefficient of translation of the ACP value to microwaves.

• Parameters: coefficient value.
• Return: No.

 void SetMin ( uint32_t vmin )

The method determines the minimum allowable voltage.

• Parameters: Voltage in MV.
• Return: No.

 void SetMax ( uint32_t vmax )

The method determines the maximum permissible voltage.

• Parameters: Voltage in MV.
• Return: No.

 void SetStart ()

The method sets the class starting flag.

• Parameters: No.
• Return: No.

 void SetStop ()

The method sets the class stop flag.

• Parameters: No.
• Return: No.

 int8_t GetValid ()

The method checks the voltage and returns the result in the form of a number.

• Parameters: No.
• Return: the number -1 is less than permissible, 0 - in the framework of permissible, 1 - more permissible.

 int32_t GetVoltage ()

The method returns the current voltage.

• Parameters: No.
• Return: tension in MV.

 void Processing ( uint32_t currentTime = millis ())

Number processing method. In the event that your loop has a definition of the current time, it is more advisable to pass this time as a parameter.

• Parameters: current time mark.
• Return: No.

 static inline uint32_t GetCoefficient ( float vref , float r1 = 0 , float r2 = 1 , float quantization = 1024 )

The utility that helps calculate the coefficient for SetCoefficient() method. If the divider is not used, then only Vref is indicated.

• Parameters: supporting voltage in microse, resistance of the upper resistor in the rumor, resistance of the lower resistor in the Oma, the level of quantization of the ADC.
• Return: recalculation coefficient.
