New to CDE - How to add properties like Port and Pins like PE GPIO or BitsIO?

Hello all,


I am trying to make my own components with following features for reading the GPIO port/pins on HCS08 series controller:

1) Allows user to select the Port

2) Allows user to select the pins to read - generate functions for reading pin value or whole port with the mask generated automatically

3) Allows user to select the pull resistor - generate functions to enable/disable pull resistor/allows to read the current pull direction (up/down)/function to read the whole port pull mask at once/function to set the pull up or down

4) Allows user to select the interrupt (KBI) - Enable/Disable interrupt and Edge sense


Currently I have tried using the BitsIO and BitIO component but it does not provide all features that I want. I am looking into the inheritance of these component and expand it but till now no success.


If any one can suggest how to add a property like Port which will be selected from the available ports on chosen controller would be a great help.


Also how can we edit the existing components to learn how it is designed without inheritance wizard - like opening the existing PE components.


Thanks in advance
