HAL mapping direction <= versus =>

Phew! I passed! Thanks Andy!

It is always helpful to check the docs for the I/O pin direction (in or out)

Thanks to both of you.

Now i need to dig more out of the syntax

There isn't any more, the arrows are not used by the machine, and there is no way to know which direction any pin is without looking at the docs or querying the live system.

Argh... My mother tongue betrayed me :blush:

I was meaning away from the syntax as you corrected me.

Thanks Andy
