Downloadable macro reference

Fc9-comp-macro.png SetOutput
Sets the output voltage of the DAC 12-Bit: Range 0-4095 
Fc9-u16-icon.png - UINT DAC_Value
The value to output to the DAC 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png Disable
Disables the DAC output. 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png Enable
Enables the DAC Output. 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png Initialise
Configures the I2C peripheral ready for communications and initialises the internal variables. DAC needs to be enabled before any output voltage can be generated. 
Fc9-void-icon.png - VOID Return



Property reference

Fc9-prop-icon.png Properties
Fc9-type-16-icon.png Disabled Pull Down
Sets the pull down resistance when the IC's DAC output is disabled. 
Fc9-type-15-icon.png Vref Voltage
Reference Voltage, Used to calculate the Voltage resolution. 
Fc9-type-21-icon.png Steps
Number of discrete output states available from the DAC. 
Fc9-type-14-icon.png Control Bits
Number of digital control bits 
Fc9-type-10-icon.png Resolution
Maximum output resolution based on number of control bits. 
Fc9-type-15-icon.png Voltage Resolution
Specifies the Resolution per digital bit in terms of Voltage. 
Fc9-conn-icon.png I2C Connections
Fc9-type-16-icon.png User Address Bits
Specifies the bottom three "user" bits of the I2C 7-bit address 
Fc9-type-16-icon.png Channel
Channel selection 
Fc9-type-5-icon.png SDA
Pin used for SDA (data signal) 
Fc9-type-5-icon.png SCL
Pin used for SCL (clock signal) 
Fc9-type-7-icon.png 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.  
Fc9-type-16-icon.png Baud Select
Baud rate option selector 
Fc9-type-14-icon.png Baud Rate
Baud rate to be used 
Fc9-conn-icon.png Simulation
Fc9-type-7-icon.png Simulate Comms
