ControlPins

Fc9-comp-macro.png ControlPins
Allows Shutdown (SHDN) and Latch (LDAC) pins to be controlled directly if enabled. 
Fc9-bool-icon.png - BOOL Shutdown
0 = Shutdown Device, 1 = Device Active 
Fc9-bool-icon.png - BOOL Latch
0 = Data output driven from DAC register, 1 = Data output locked 
Fc9-void-icon.png - VOID Return


Disable

Fc9-comp-macro.png Disable
Disables the DAC output. 
Fc9-u8-icon.png - BYTE Channel
0=DAC Channel 0 , 1=DAC Channel 1 
Fc9-void-icon.png - VOID Return


Enable

Fc9-comp-macro.png Enable
Enables the DAC Output. 
Fc9-u8-icon.png - BYTE Channel
0=DAC Channel 0 , 1=DAC Channel 1 
Fc9-void-icon.png - VOID Return


Initialise

Fc9-comp-macro.png Initialise
Configures the SPI 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


SetOutput

Fc9-comp-macro.png SetOutput
Sets the output voltage of the DAC 8-Bit: Range 0-255 10-Bit: Range 0-1023 12-Bit: Range 0-4095 
Fc9-u8-icon.png - BYTE Channel
0=DAC Channel 0 , 1=DAC Channel 1 
Fc9-u16-icon.png - UINT DAC_Value
The value to output to the DAC 
Fc9-void-icon.png - VOID Return



Property reference

Fc9-type-16-icon.png DAC IC
Selects which DAC IC is connected and therefore the bit depth available. 
Fc9-type-16-icon.png Gain Option
Selects the maximum reference value for the DAC 
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 SPI Connections
Fc9-type-16-icon.png Channel
SPI Channel selector 
Fc9-type-16-icon.png Prescale
Prescale option selector 
Fc9-type-5-icon.png MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. 
Fc9-type-16-icon.png MOSI Remap Pin
Select which the target pin to assign the MOSI hardware pin functionality. 
Fc9-type-5-icon.png MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. 
Fc9-type-16-icon.png MISO Remap Pin
Select which the target pin to assign the MISO hardware pin functionality. 
Fc9-type-5-icon.png CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master. 
Fc9-type-16-icon.png CLK Remap Pin
Select which the target pin to assign the CLK hardware pin functionality. 
Fc9-type-5-icon.png CS / SS
Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device.  
Fc9-type-7-icon.png Use SHDN Pin
Allows the SHDN pin to be driven from an output pin on the microcontroller. If not used then tie the SHDN pin to VCC to allow the DAC to function. 
Fc9-type-7-icon.png Use LDAC Pin
Allows the LDAC pin to be driven from an output pin on the microcontroller. If not used then tie the LDAC pin to GND to allow the DAC to function.
