(re)define port usage Topic is solved

[Sebastian]

Hello,

is it possible to define an port fist as 32bit and later as 4bit for example?

In my case: ( XEF232-1024-FB374 )
Read at "startup" P32A12 -P3219 on tile[2]. Later in "normal" usage I want
to give out something on P4C0 - P4C3 even on tile[2].

So that means, that P32A is only used once at the initialization.

thanks,
Sebastian

Short answer: yes

Long answer: the architecture supports this but the tools assume that a port is used from boot until the program stops, so you may have to explicitly turn ports on and off. Two functions that can help with this are:

Code: Select all

void set_port_use_on(void port p);
void set_port_use_off(void port p);

Cheers,
Henk

Thank you Hank.

That look linke an rethinking of the port usage :)
