|

|
* The following functions are available on all platforms, but there may
|
||
|
|
* be variations in the function signature (i.e. parameters) and
|
||
|
|
* behaviour. These functions are typically called by platform-specific
|
||
|
|
* parts of drivers, and applications that aren't intended to be
|
||
|
|
* portable:
|
||
|
|
* - gpio_pin_is_low()
|
||
|
|
* - gpio_pin_is_high()
|
||
|
|
* - gpio_set_pin_high()
|
||
|
|
* - gpio_set_pin_group_high()
|
||
|
|
* - gpio_set_pin_low()

|
* - gpio_set_pin_group_low()

|
* - gpio_toggle_pin()
