I am working with CodeWarrior 5.1 for S12(X). My target is 9S12XA256.
I am adding the Capture component to trigger on both edges of an input capture pin. There is not method to read the pin state to determine if the event was triggered by a rising or falling edge.
As a solution, I tried to add a BitIO to get the methods to read the pin state and guess what happened? Processor Expert told me the pin was already in use by the Capture component.
Aside from writing my own code to go directly to the registers and defeating the whole purpose of PE, how do I know the edge type that triggered the event?
Now, I have one more issue. There is no method to change the detection edge of the input capture pin in real-time. If I want to change the edge polarity from high-to-low or low-to-high as I decode an incoming signal, how could I do it?
Am I crazy by assuming such basic functions should already be part of the component, or am I just overlooking something? Thanks.
