Overview

Package reg provides primitives for retrieving and modifying hardware registers.

This package is only meant to be used with `GOOS=tamago GOARCH=arm` as supported by the TamaGo framework for bare metal Go on ARM SoCs, see https://github.com/f-secure-foundry/tamago.

func Set

func Set(addr uint32, pos int)

func Set16

func Set16(addr uint32, pos int)

func SetN

func SetN(addr uint32, pos int, mask int, val uint32)

func SetN16

func SetN16(addr uint32, pos int, mask int, val uint16)

func Wait

func Wait(addr uint32, pos int, mask int, val uint32)

Wait waits for a specific register bit to match a value. This function cannot be used before runtime initialization with `GOOS=tamago`.

func Wait16

func Wait16(addr uint32, pos int, mask int, val uint16)

Wait16 waits for a specific register bit to match a value. This function cannot be used before runtime initialization with `GOOS=tamago`.

func WaitFor

func WaitFor(timeout time.Duration, addr uint32, pos int, mask int, val uint32) bool

WaitFor waits, until a timeout expires, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or if it timed out (false). This function cannot be used before runtime initialization.

func WaitFor16

func WaitFor16(timeout time.Duration, addr uint32, pos int, mask int, val uint16) bool

WaitFor16 waits, until a timeout expires, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or if it timed out (false). This function cannot be used before runtime initialization with `GOOS=tamago`.

func WaitSignal

func WaitSignal(done chan bool, addr uint32, pos int, mask int, val uint32) bool

WaitSignal waits, until a channel is closed, for a specific register bit to match a value. The return boolean indicates whether the wait condition was checked (true) or cancelled (false). This function cannot be used before runtime initialization.

func Write

func Write(addr uint32, val uint32)

func Write16

func Write16(addr uint32, val uint16)

func WriteBack

func WriteBack(addr uint32)

func WriteBack16

func WriteBack16(addr uint32)
