Properties |
|
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. | |
|
Connections |
|
|
Device Address |
| The address pins are used to allow up to 8 individual devices to be connected onto an I2C bus. Sets the state of the pins. | |
|
|
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. | |
