       Where `framebuffer_{ptr,width,height,pitch}` represent the corresponding info

     

       19
       19
       -
       about the framebuffer to use for this given instance.

     

       30

       +
       Where `framebuffer_ptr, width, height, pitch` and `{red,green,blue}_mask_{size,shift}`

     

       31
       31
       +
       represent the corresponding info about the framebuffer to use for this given instance.

       The meaning of the other arguments can be found in `flanterm_backends/fb.h`.

       21
       35
        
       To then print to the terminal instance, simply use the `flanterm_write()`

     

       22
       36
        
       function on the given instance. For example:

     

       23
       37
        
       ```c

     

       24

       ## Usage

     

       6
       6
       +
       First, add the package to your build.zig.zon:

     

       7
       7
       +
       `zig fetch --save git+https://tangled.sh/@sydney.blue/flanterm.zig#trunk`

     

       8
       8
       +
       Then, add the following to your build.zig:

     

       9
       9
       +
       ```zig

     

       10
       10
       +
       const flanterm_dep = b.dependency("flanterm", .{});

     

       11
       11
       +
       const flanterm_mod = flanterm.module("flanterm");

     

       12
       12
       +
       exe.root_module.addImport("flanterm", flanterm_mod);

     

       13
       13
       +
       ```

     

       14
       14
       +
       

     

       15
       15
       +
       Now, you can import the `flanterm` module and use the helpers. More

     

       16
       16
       +
       bindings will be added as needed, feel free to contribute anything

     

       17
       17
       +
       you would find useful.
