|
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 |
|
|
Disable |
| Disables the DAC output. | |
| - VOID
|
Return |
|
|
Enable |
| Enables the DAC Output. | |
| - VOID
|
Return |
|
|
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 |
Property reference
|
Properties |
|
DAC IC |
| Selects which DAC IC is connected and therefore the bit depth available. | |
|
|
Disabled Pull Down |
| Sets the pull down resistance when the IC's DAC output is disabled. | |
|
|
Voltage Reference |
| Sets the Voltage reference option | |
|
|
Gain Option |
| Provides a 1x or 2x gain on the output. For 2x gain the vref must be max 1/2 VCC. | |
|
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 |
|
|
Simulation |
|
|
DAC Output Scope Trace |
| Selects if the scope traces are automatically generated or not | |
|
|
Scope Traces |
| Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window. | |
|
|
Console Data |
| Selects if the console data is automatically generated or not | |
|
|
API |
| Specifies the injector component on the panel to interact with to provide comms simulation. | |
