Detailed Description

Resource allocation manager for PPI module.

Used to avoid the need for compile-time assignment of channels or channel groups to functions. Also provides an abstraction that will ultimately support the supervisor calls required for soft devices.

Member Function Documentation

configure()

static uint32_t nrfcxx::periph::PPI::configure ( int  ppidx, event_reference_type  eep, task_reference_type  tep  )

inlinestatic

Configure a PPI channel.

Parameters

ppidx	an PPI channel index as returned from request()
eep	the event endpoint of the connection
tep	the task endpoint of the connection

Returns

0 on success, or a nonzero error code

group_release()

static int nrfcxx::periph::PPI::group_release ( int  ppi )

static

Release a previously allocated PPI channel group.

Returns

0 on success, or a negative error code.

group_request()

static int nrfcxx::periph::PPI::group_request ( )

static

Allocate a PPI channel group for application use.

Returns

the PPI channel group index, or a negative error code.

release()

static int nrfcxx::periph::PPI::release ( int  ppi )

static

Release a previously allocated PPI channel.

Returns

0 on success, or a negative error code.

request()

static int nrfcxx::periph::PPI::request ( )

static

Allocate a PPI channel for application use.

Returns

the PPI channel index, or a negative error code.
