DAC (MCP4725) component

Component to drive a 12-bit digital to analogue converter (DAC) IC from Microchip via an I2C interface.

Detailed description

No detailed description exists yet for this component

Examples

No additional examples






Macro reference

Disable

Disable
Disables the DAC output. 
- VOID Return


Enable

Enable
Enables the DAC Output. 
- VOID Return


Initialise

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. 
- VOID Return


SetOutput

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


Property reference

Properties
Disabled Pull Down
Sets the pull down resistance when the IC's DAC output is disabled. 
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. 
I2C Connections
User Address Bits
Specifies the bottom three "user" bits of the I2C 7-bit address 
Channel
Channel selection 
SDA
Pin used for SDA (data signal) 
SCL
Pin used for SCL (clock signal) 
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.  
Baud Select
Baud rate option selector 
Baud Rate
Baud rate to be used 
Simulation
Simulate Comms
