PSoC™ 5, 3 & 1

[Anonymous]

I have two projects. One has analog pin configured to comparator.

   

Another projects ( the same code) has pin configured as resistive pullup/down digital output with enable ( see pict).

   

When pin has fixed enabled value to zero ( disabled) the comparator stops working, no analog pass through.

There is not my case ,in the manual, with hardware enable pin. However Manual helpfull thanks.

   

By the way Do You know where is the manual for PSOC4 which refers the same issue.

   

I have similar problem with PSOC4 as well.

I am not aware of a specifc applicable ap note for PSOC 4 GPIO,

   

but you can compare the GPIO chapter in the PSOC 3 TRM to the

   

4 TRM.

       

The PSOC 4 TRM is available at -

You could also post a case if there are any differences between PSOC 4 GPIO and 3/5,and

   

post back here for the rest of the forum.

It's uncomparable, because PSOC3 lack HSIOM registers.

   

And these registers don' reflect all routes as it is in PSOC3/5.

   

It will take ages for us-users to figure out what is going on in PSOC4 if such guru like You don't know it.

Not being a Guru thats why I suggested you file a CASE, and post results for all,

   

so I can benefit from gurus teachings.
