ControlPins

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


Disable

Disable
Disables the DAC output. 
- VOID Return


Enable

Enable
Enables the DAC Output. 
- VOID Return


Initialise

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. 
- VOID Return


SetOutput

SetOutput
Sets the output voltage of the DAC 8-Bit: Range 0-255 10-Bit: Range 0-1023 12-Bit: Range 0-4095 
- UINT DAC_Value
The value to output to the DAC 
- VOID Return


Property reference

Properties
DAC IC
Selects which DAC IC is connected and therefore the bit depth available. 
Gain Option
Selects the maximum reference value for the DAC 
Vref Voltage
Reference Voltage, Used to calculate the Voltage resolution. 
Steps
Number of discrete output states available from the DAC. 
Control Bits
Number of digital control bits 
Resolution
Maximum output resolution based on number of control bits. 
Voltage Resolution
Specifies the Resolution per digital bit in terms of Voltage. 
SPI Connections
Channel
SPI Channel selector 
Prescale
Prescale option selector 
MOSI
SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. 
MOSI Remap Pin
Select which the target pin to assign the MOSI hardware pin functionality. 
MISO
SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. 
MISO Remap Pin
Select which the target pin to assign the MISO hardware pin functionality. 
CLK
SPI Clock Pin CLK - The Clock signal is driven by the SPI master. 
CLK Remap Pin
Select which the target pin to assign the CLK hardware pin functionality. 
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.  
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. 
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. 
Simulation
Simulate Comms
