#160312 - Such a #define lies to the user Responding to: ???'s previous message |
But if the SET_DDR #define does nothing, it does not fulfill its promise.
It is correct that no action is needed when setting the pin as an output. But when configuring the pin as an input, the #define is required to make sure that the pin is driven high. The #define should either make sure the pin works as expected or the user should not hide the functionality of the port. |
