RTOS/CC2640R2F: Is it possible to "reverse" pin_init(), i2c_init(), etc.

Hi,

This is a very basic question. As I understand it, each peripheral's _init() function configures pins from high Z into appropriate inputs/outputs.

Each peripheral's _open() function locks pins and prevents other peripherals from using them, like a mutex. _open() can be reversed with _close().

Is there a similar reverse function for _init() that returns the pins to high Z? I'm trying to save as much power as possible.

Thanks,

Rich

Hi Rich,

The "init" functions typically never configure the IO state, the exception being PIN_init() which setup the "default" statue of unused pins added to the "default settings table". Beside that, IO configurations is only done during the PIN_open() calls.

Thanks for replying.

So I should just _close() all the peripherals, then use PIN_config() to turn them back to their pre _init() states?
