# Matrix Initialization Code
# Keyboard Initialization Code
Before a keyboard can be used the hardware must be initialized. QMK handles initialization of the keyboard matrix itself, but if you have other hardware like LEDs or i&#xb2;c controllers you will need to set up that hardware before it can be used.
There are several steps in the keyboard initialization process. Depending on what you want to do, it will influence which function you should use.
These are the three main initialization functions, listed in the order that they're called.
### Example `matrix_init_user()` Implementation
* `keyboard_pre_init_*` - Happens before most anything is started. Good for hardware setup that you want running very early.
* `matrix_init_*` - Happens midway through the firmware's startup process. Hardware is initialized, but features may not be yet.
* `keyboard_post_init_*` - Happens at the end of the firmware's startup process. This is where you'd want to put "customization" code, for the most part.
!> For most people, the `keyboard_post_init_user` function is what you want to call. For instance, this is where you want to set up things for RGB Underglow.
## Keyboard Pre Initialization code
This runs very early during startup, even before the USB has been started.
Shortly after this, the matrix is initialized.
For most users, this shouldn't be used, as it's primarily for hardware oriented initialization.
However, if you have hardware stuff that you need initialized, this is the best place for it (such as initializing LED pins).
### Example `keyboard_pre_init_user()` Implementation
This example, at the keyboard level, sets up B1, B2, and B3 as LED pins.
```c
void matrix_init_user(void) {
// Call the keymap level matrix init.
void keyboard_pre_init_user(void) {
// Call the keyboard pre init code.
// Set our LED pins as output
DDRB |= (1<<1);

### `keyboard_pre_init_*` Function Documentation
* Keyboard/Revision: `void keyboard_pre_init_kb(void)`
* Keymap: `void keyboard_pre_init_user(void)`
## Matrix Initialization Code
This is called when the matrix is initialized, and after some of the hardware has been set up, but before many of the features have been initialized.
This is useful for setting up stuff that you may need elsewhere, but isn't hardware related nor is dependant on where it's started.
### `matrix_init_*` Function Documentation
* Keyboard/Revision: `void matrix_init_kb(void)`
* Keymap: `void matrix_init_user(void)`
## Keyboard Post Initialization code
This is ran as the very last task in the keyboard initialization process. This is useful if you want to make changes to certain features, as they should be initialized by this point.
### Example `keyboard_post_init_user()` Implementation
This example, running after everything else has initialized, sets up the rgb underglow configuration.
```c
void keyboard_post_init_user(void) {
// Call the post init code.
rgblight_enable_noeeprom(); // enables Rgb, without saving settings
rgblight_sethsv_noeeprom(180, 255, 255): // sets the color to teal/cyan without saving
rgblight_mode_noeeprom(RGBLIGHT_MODE_BREATHING + 3); // sets mode to Fast breathing without saving
}
```

* Keyboard/Revision: `void keyboard_post_init_kb(void)`
* Keymap: `void keyboard_post_init_user(void)`
# Matrix Scanning Code
Whenever possible you should customize your keyboard by using `process_record_*()` and hooking into events that way, to ensure that your code does not have a negative performance impact on your keyboard. However, in rare cases it is necessary to hook into the matrix scanning. Be extremely careful with the performance of code in these functions, as it will be called at least 10 times per second.

### Example Implementation
### Example Implementation
This is an example of how to add settings, and read and write it. We're using the user keymap for the example here. This is a complex function, and has a lot going on. In fact, it uses a lot of the above functions to work!
