using parameters when creating component

[Anonymous]

Hi, 

   

i'm fairly new to cypress PSoC and this is the first component i'm trying to create.

   

I've setup a parameter for my symbol as a boolean, but now i'd like my API to execute different code depending on it's status.

   

I've searched through the component author guide and watched some tutorials, but i can't find any reference on how to do this.

       

any help would be greatly appreciated.

   

i'm using creator 3.3

       

best regards,

   

Damian

In the API template file use a

   

#if(‘$<parameter>‘ == 0) for conditional compilation

   

or

   

if (‘$<parameter>‘) for program flow

   

where <parameter> is the name you have given in the symbol creation dialog.

        One extra comment: default Cypress constants for use in API parameters evaluation are 'true' and 'false' (lowercase letters), not 'True' / 'False'. So use lowercase only. For example, for both parameters being true, the result of compilation will be different: #define CASE1 (($param1==true) & ($param2==true)) Compiled file: #define CASE1 true And this line will not be evaluated: #define CASE1 (($param1==1) & ($param2==1)) Compiled file: #define CASE1 (($param1==1) & ($param2==1))

I have learnt not to test booleans for true or false. In your examples we were taught to write

   

#define CASE1 ((`$param1`)&&(`$param2`))

   

C-language defined false to be zero, so true is defined as being non-zero.

   

Imagine what the different behaving is, when $param1 has the value of 27 (or any other).

Thanks Bob and odissey1 this was what i needed to know.

   

I was using the < and > characters and the ' instead of ` characters.
