What is the program execution model in C4 ?

[id4]

Hi,

I am wondering, how does the c4 program code is executed ? parallel or sequential ?

For example, I have some actions associated with a key/doorbell "press" and then some different actions associated with the same key/doorbell "release", because, I want them to execute in parallel.

Now, when I press (and release) the key/doorbell, I see that it takes long time to complete both the actions (note I do have some delays between certain ops).

I am wondering, this could be because the the single threaded execution of the code associated with both "press" and "release".

Can anyone clarify this ? RyanE ?

Thanks
