## Changelog
|
||||
|
||||
0.6.0: Breaking change. Refactor DMD a bit to rename the function
|
||||
`read` to `read_word`, and added a `read_byte` function
|
||||
as well. Also refactored the CPU mnemonic lookup to be
|
||||
more efficient using a lookup table instead of a HashMap.
|
||||
Lastly, fixed a bug in the DUART that set the wrong
|
||||
delay for one baud rate.
|
||||
|
||||
0.5.0: Non-breaking but major change. `dmd_core` now presents a
|
||||
C compatible API to make interacting with C and C++ code
|
||||
easier, without needed to write a full stub library.

## Emulator Reference Implementations
|
||||
|
||||
For a reference implementation emulator that uses this library,
|
||||
please see the ["DMD" project on GitHub](https://github.com/sethm/dmd).
|
||||
Two implementations of DMD 5620 emulator use this core library.
|
||||
|
||||
* The Linux native GTK application `dmd5620`: [https://github.com/sethm/dmd_gtk](https://github.com/sethm/dmd_gtk)
|
||||
|
||||
* The Macintosh native Cocoa application `DMD 5620`: [https://github.com/sethm/dmd_mac](https://github.com/sethm/dmd_mac)
|
||||
|
||||
A Windows native application is in the works.
