HDC2010驱动代码

Texas Instruments HDC2010 Arduino Library ========================================== Description: The HDC2010 Library for Arduino allows for configuration and use of the HDC2010 without the need to use I2C or know the register mapping of the device. Feel free to modify and reuse this library as you see fit. This code is released AS-IS into the public domain. No guarantee or warranty is given. This code will not be supported by Texas Instruments after release. --------------------------------------------------------------------------------------- Installation: Extract or copy the HDC2010 Arduino Library folder into the 'libraries' folder found in your Arduino Sketchbook. The example sketch will then be available under 'custom libraries' when you select File-> Examples. --------------------------------------------------------------------------------------- Contents: HDC2010.cpp - C++ File defining behavior of HDC2010 methods HDC2010.h - Header file for HDC2010.cpp keywords.txt - Keywords from HDC2010.h library.properties - Properties file for HDC2010 library Examples - Holds HDC2010 example sketch ---------------------------------------------------------------------------------------- Library Functions: HDC2010(uint8_t addr) - Initializes an HDC2010 object void begin(void) - Equivalent to wire.Begin(), Joins I2C Bus float readTemp(void) - Returns the temperature in degrees C float readHumidity(void) - Returns the relative humidity void enableHeater(void) - Enables the heating element void disableHeater(void) - Disables the heating element void setLowTemp(float temp) - Sets the lower temperature threshold (in celcius). Temperature may not be exact due to 8 bit quantization. void setHighTemp(float temp) - Sets the upper temperature threshold (in celcius). Temperature may not be exact due to 8 bit quantization. void setHighHumidity(float humid) - Sets the upper humidity threshold (as a %). Humidity may not be exact due to 8 bit quantization. void setLowHumidity(float humid) - Sets the lower humidity threshold (as a %). Humidity may not be exact due to 8 bit quantization. float readLowHumidityThreshold(void) - Returns contents of low humidity threshold register float readHighHumidityThreshold(void) - Returns contents of high humidity threshold register float readLowTempThreshold(void) - Returns contents of low temperature threshold register (in C) float readHighTempThreshold(void) - Returns contents of high temperature threshold register (in C) void triggerMeasurement(void) - Triggers a manual temperature/humidity reading. Use to start the taking of regular measurements. void reset(void) - Triggers a software reset, all registers are returned to default values void enableInterrupt(void) - Enables the interrupt/DRDY pin void disableInterrupt(void) - Disables the interrupt/DRDY pin (High Z) uint8_t readInterruptStatus(void) - Reads the status of the interrupt register. The results can be interpreted to know which interrupts have been generated. The HDC2010 datasheet explains the contents of this register. void clearMaxTemp(void) - Clears the Maximum temperature register. void clearMaxHumidity(void) - Clears the Maximum humidity register float readMaxTemp(void) - Reads the maximum temperature register float readMaxHumidity(void) - Reads the maximum humidity register void enableThresholdInterrupt(void) - Enables high and low temperature/humidity interrupts void disableThresholdInterrupt(void) - Disables high and low temperature/humidity interrupts void enableDRDYInterrupt(void) - Enables data ready interrupt void disableDRDYInterrupt(void) - Disables data ready interrupt void setTempRes(int resolution) void setHumidRes(int resolution) Sets Temperature & Humidity Resolution, 3 options 0 - 14 bit 1 - 11 bit 2 - 9 bit default - 14 bit void setMeasurementMode(int mode) Sets measurement mode, 3 options 0 - Temperature and Humidity 1 - Temperature only 2 - Humidity only default - Temperature & Humidity void setRate(int rate) Sets reading rate, 8 options 0 - Manual 1 - reading every 2 minutes 2 - reading every minute 3 - reading every ten seconds 4 - reading every 5 seconds 5 - reading every second 6 - reading at 2Hz 7 - reading at 5Hz default - Manual void setInterruptPolarity(int polarity) Sets Interrupt polarity, 2 options 0 - Active Low 1 - Active High default - Active Low void setInterruptMode(int polarity) Sets Interrupt mode, 2 options 0 - Level sensitive 1 - Comparator mode default - Level sensitive
