Hi everybody!

Hi Jorgen
A very simple Boolean function that is executed by FlowCode is the "Decision". You know that in a FC Decision is checked if a concrette variable fulfils a condition, for example "If switch = 1?" Here the variable under test is the "switch". That is also a Boolean expresion: "Switch is TRUE?" The ON (=1) condition corresponds to TRUE, while the OFF (=0) condition corresponds to FALSE. Accordingly, there are two branches after a FlowCode Decision, the one that is called "yes" corresponds to Boolean TRUE while the other that called "no" corresponds to Boolean FALSE.

Hi Fotio!

Thank you for your help.

I understand the function of BOOL. It's more how to handle it in FC I think when you create the variable and handle it in an if function. I would be very happy if you could make a small example.

Thanks in advance.

Hello,

Using a bool in a decision should be straightforward.

If b1 is your boolean variable

To check if b1 is set you could enter the following into a decision icon

Code: Select all

b1

or

Code: Select all

b1 = 1

To check if b1 is clear you could do

Code: Select all

!b1

or

Code: Select all

b1 = 0

Are you testing on hardware or in simulation?

Hi Ben!

Thank you, now I am in business. It´s a new kind of variable for me. At the moment I test it in simulation, but later in "real wold". I know I have config the Pic before downloading.

Once again, thank you.
