Property reference
Address
This property is of type Fixed list of ints and can be referenced with the variable name Addr.
Selects the correct device address based on the ADDR pin connection to VDD or VSS.
Channel
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c1::CHANNEL.
Channel selection
SDA
This property is of type Single digital pin and can be referenced with the variable name cal_i2c1::SDA.
Pin used for SDA (data signal)
SCL
This property is of type Single digital pin and can be referenced with the variable name cal_i2c1::SCL.
Pin used for SCL (clock signal)
Baud Select
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c1::BAUD_LIST.
Baud rate option selector
Baud Rate
This property is of type Signed integer and can be referenced with the variable name cal_i2c1::BAUD.
Baud rate to be used
Stop Delay
This property is of type True or false and can be referenced with the variable name cal_i2c1::StopDel.
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.
Simulation Type
This property is of type Fixed list of ints and can be referenced with the variable name SimType.
No additional information
Scope Traces
This property is of type True or false and can be referenced with the variable name cal_i2c1::ScopeTraces.
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
This property is of type True or false and can be referenced with the variable name cal_i2c1::ConsoleData.
Selects if the console data is automatically generated or not
Injector
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c1::Injector.
