Downloadable macro reference

ReadPressureFloat
Reads the pressure as a floating point value in Bars. Calls the ReadPressureRaw function and then converts to a meaningful value. 
[[File:]] - Return


Reset
Resets the device 
- VOID Return


I2C_Read_Register
Reads a byte value from a register on the device 
- BYTE Address
 
- BYTE Return


ReadTemperatureFloat
Reads the temperature as a floating point value in °C. Resultion sets the return bit value and conversion time. Calls the ReadTemperatureRaw function and then converts to a meaningful value. 
[[File:]] - Return


Altitude
Calculates the altitude based on difference between actual pressure and the pressure at the sea level P0=1013.25 hPa.  
[[File:]] - Return


Forced_Read
 
- VOID Return


I2C_Write_Register
Writes a byte value to a register on the device 
- BYTE Address
 
- BYTE Value
 
- VOID Return


Initialise
Starts up the I2C bus and initialises the pressure sensor ready for use. Returns 1 for a sucessful startup. Returns 0 for a failed startup or no device detected. 
- BYTE Return

Baud Rate
Baud rate to be used 
Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
