Checking Inputs with a seperate cog

[JMLStamp2p]

Good Evening,
I am trying to start a new cog to constantly look at inputs and run certain Methods contingent upon with Pin went High. I am working with Pin-7
at the moment and also have it pulled Low through a resistor and a push button to send it high. For some reason I can't get both cogs "Full_Duplex_Serial" and the "Button_Down" cog to Blink the LED's at the same time. With the code as is, Pins 16 & 23·are Blinking and it appears that my code is not correct in my Botton_Down Method. Could someone gve me some advise ?

When you start a separate cog, you also get a separate DIRA register which is initialized to zero (inputs).
You need to move the "DIRA[ Pin ]~~" to the start of the "Button_Down" method.

And this code:



repeat While Temp := 0



certainly doesn't do what you intended.

Thank You Mike for your help, and Nick could you give me an example of what would. New to the Prop :>)
Thanks,

I think what you need is

·"repeat while ina[7] == 0"

This will continually scan pin 7 also note the use of == when testing for equality(not :=)
