Hello Lawrence,
When we configure any IP from sysconfig, we get a corresponding generated code at compile time.
In this example we are configuring CONFIG_GPIO2's Pin direction as Input which gets reflected in ti_drivers_config.h as:
#define CONFIG_GPIO2_DIR (GPIO_DIRECTION_INPUT)
This macro "CONFIG_GPIO2_DIR" is in turn used in ti_drivers_config.c to actually set the direction by calling the API GPIO_setDirMode:
GPIO_setDirMode(baseAddr, CONFIG_GPIO2_PIN, CONFIG_GPIO2_DIR);
If user wants to change the GPIO direction dynamically, he can call the API GPIO_setDirMode by varying the 2nd argument between GPIO_DIRECTION_INPUT and GPIO_DIRECTION_OUTPUT wherever required.
There's no way to configure syscfg such that the code changes at runtime because it's a one time config taking effect at compile time.
Does this answer the query?
