# Uxn11
|
|
|
|
An emulator for the [Uxn stack-machine](https://wiki.xxiivv.com/site/uxn.html), written in ANSI C.
|
|
|
|
## Uxn11/System
|
|
|
|
This emulator's system device supports changing a stack's location to a page of memory. The default memory mapping is as follows:
|
|
|
|
- `0000-ffff`, as **RAM**.
|
|
- `10000-100ff`, as **working stack**.
|
|
- `10100-101ff`, as **return stack**.
|
|
|
|
To use the last page of ram(`0xff00`) to host the working stack:
|
|
|
|
```
|
|
#ff .System/wst DEO
|
|
```
|
|
|
|
The stack mapping is 254 bytes of data, a byte for the pointer and a byte for an error code.
|
|
|
|
## Graphical
|
|
|
|
All you need is X11.
|
|
|
|
```
|
|
gcc src/uxn.c src/devices/system.c src/devices/screen.c src/devices/controller.c src/devices/mouse.c src/devices/file.c src/devices/datetime.c src/uxn11.c -D_POSIX_C_SOURCE=199309L -DNDEBUG -Os -g0 -s -o bin/uxn11 -lX11
|
|
```
|
|
|
|
## Terminal
|
|
|
|
If you wish to build the emulator without graphics mode:
|
|
|
|
```sh
|
|
cc src/devices/datetime.c src/devices/system.c src/devices/file.c src/uxn.c -DNDEBUG -Os -g0 -s src/uxncli.c -o bin/uxncli
|
|
```
|
|
|
