I set the above re3to digital input in config setting but found that i still can get the pin for extra connection in any output connection. Any update?

Hello,

Here is an updated FCD with the RE3 pin added.

Actually the pin which is multiplexed with MCLR can only be input and this is configurable as you said. You rightly said that this pin should not be in the output list. But still flowcode is not doing this obvious thing. I'll have a look at Fcd if anything could be done I'll let you know.

Hi Ben,
I was posting from my mobile..it seems that we are trying to post at similar time...But I have tried your FCD..

Code: Select all

PortMask4=0x0F

With this PORTE<3> still available as output.

Code: Select all

PortMask4=0x07

If I change to the above, PORTE<3> will be no more in output but the problem is it will be no more as input also..
In that case, we have to use c code for input..can't use FC component..

Hi Enamul,

Yes i'm afraid either the pin is unavailable or is available for both input and output in Flowcode, there is currently no way to define a pin as input only. Maybe a good addition for the future?

Yes, that's I replied in my first post..But if we remove that in FCD and use c code for input that could solve problem temporarily. Isn't that?
