Editing component connections
To edit how an external component is connected to a microcontroller, first select the component in the panel and then click on the connections button in the properties tab. The Component Pins Connection dialog will appear allowing the connections to be viewed and edited.
Pin Name
The names of the pins of the external component are shown in this column along with a graphic image indicating the status of the connection. A green tick indicates that the connection is OK. A red cross indicates that the pin is not currently connected to the microcontroller but needs to be for the device to function properly. A yellow question mark indicates that the pin is unconnected but that it is not essential to the correct functioning of the device.
Port
The microcontroller port that an external pin is connected to is shown in this column.
Bit
The microcontroller port bit that an external pin is connected to is shown in this column.
Status
Status information about a pin is displayed here. This may include details of possible conflict between devices connected to the same microcontroller pin. In addition, certain components must connect some pins to the same port as other pins in the device. In this case, the status area displays this information and the user is unable to change the port in the Connect to section
Connect to
Use these lists to determine the microcontroller pin to connect to. If a list in unavailable then this means that the pin's connection is determined by that of another pin. A message will appear in the status information if this is the case.
To change the connection first highlight the pin by clicking on a pin under Pin Name.
