why use pin signals?

juliancox — Mon, 12 Feb 2018 12:00:55 GMT

Almost all of the pins on my MC9s08 CPU are associated with a component (Processor Expert) and in the component properties I have given each one a pin signal. e.g. for Bit1.BitIO the pin signal is Button_1. How can I use the Pin Signal to make my code more readable? For example: - can I use "if (Button_1)....." instead of "if (Bit1.GetVal()).....". If the answer is no, what is the purpose of Pin Signals?

Hi Julian,

the signal name is used for documentation purpose only, see the signals text file inside the generated Documentation folder.

But you can give the component any name you want:

So you could name it 'Button1' and then you can use 'Button1_GetVal()' and so on.

I hope this helps,

Erich

Thanks Erich, I did not realise that I could change the component name, so now I will change all of the names. I have 15 BitIO components and I keep forgetting which one does what - so problem solved`!
