MMIO class

MMIO wrapper functions for the Linux userspace /dev/mem device.

c-periphery MMIO documentation.

Constructors

MMIO(int base, int size)
Maps the region of physical memory specified by the base physical address and size in bytes, using the default /dev/mem memory character device.
MMIO.advanced(int base, int size, String path)
Map the region of physical memory specified by the base physical address and size in bytes, using the specified memory character device path.

Methods

dispose() → void
Releases all interal native resoures.
getErrno() int
Returns the libc errno of the last failure that occurred.
getMMIOinfo() String
Returns a string representation of the MMIO handle.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
read(int offset, int len) List<int>
