Types

type Chan

type Chan byte

Chan represents PPI channel. There are 31 channels numbered from 0 to 31. Channels from 20 to 31 are pre-programmed.

Pre-programmed channels.

func (Chan) Disable

func (c Chan) Disable()

Enable atomically disables channel c.

func (Chan) EEP

func (c Chan) EEP() *te.Event

EEP returns the value of Event End Point register for channel c.

func (Chan) Enable

func (c Chan) Enable()

Enable atomically enables channel c.

func (Chan) Enabled

func (c Chan) Enabled() bool

Enabled reports whether channel c is enabled.

func (Chan) FTEP

func (c Chan) FTEP() *te.Task

FTEP returns the value of Fork Task End Point register for channel c. nRF52.

func (Chan) Mask

func (c Chan) Mask() Channels

func (Chan) SetEEP

func (c Chan) SetEEP(e *te.Event)

SetEEP sets the value of Event End Point register for channel c.

func (Chan) SetFTEP

func (c Chan) SetFTEP(t *te.Task)

SetFTEP sets the value of Fork Task End Point register for channel c. nRF52.

func (Chan) SetTEP

func (c Chan) SetTEP(t *te.Task)

SetTEP sets the value of Task End Point register for channel c.

func (Chan) TEP

func (c Chan) TEP() *te.Task

TEP returns the value of Task End Point register for channel c.

type Channels

type Channels uint32

func Enabled

func Enabled() Channels

Enabled returns a bitfield where each bit corresponds to one channel. Zero means channel is disabled, one means channel is enabled.

func (Channels) Disable

func (c Channels) Disable()

Disable atomically disables channels sepcified by c.

func (Channels) Enable

func (c Channels) Enable()

Enable atomically enables channels sepcified by c.

type Group

type Group int8

Group repersents PPI channel group. There are 4 channel groups (6 in nRF52) numbered from 0 to 3 (5 in nRF52).

func (Group) Channels

func (g Group) Channels() Channels

Channels returns channels that belongs to the group g.

func (Group) DIS

func (g Group) DIS() Task

DIS returns task that can be used to disable channel group g.

func (Group) EN

func (g Group) EN() Task

EN returns task that can be used to enable channel group g.

func (Group) SetChannels

func (g Group) SetChannels(c Channels)

SetChannels sets channels that belongs to the group g.

type Task

type Task byte

func (Task) Task

func (t Task) Task() *te.Task
