|
Small library for interfacing with the Linux framebuffer.
|
||
|
|
|
||
|
|
Compile and install:
|
||
|
|
```sh
|
||
|
|
make
|
||
|
|
sudo make install
|
||
|
|
```
|
||
|
|
|
||
|
|
Usage example:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#define FB_IMPLEMENTATION // If linking dynamically with the library, omit this line
|
||
|
|
#include <fb.h>
|
||
|
|
|
||
|
|
int main() {
|
||
|
|
Framebuffer fb = newFramebuffer("/dev/fb0");
|
||
|
|
writeColourToFramebuffer(&fb, (Pixel){100, 100}, (Colour){255, 0, 0, 0});
|
||
|
|
destroyFramebuffer(&fb);
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
* Don't try to write to the framebuffer while in an X.org or Wayland session
|
||
|
|
* Your user must be in the `input` group before using, run the command `sudo usermod -a -G video $USER` to get permissions. Otherwise, the library will abort.
|
||
|
|
* This is intended to be a small library to make it easier for anyone to draw things to the screen. Just pixel rendering.
