part, <code>// Key Matrix to LED Index</code>, tells the system what key this LED represents by using the key's electrical matrix row & col. The second part, <code>// LED Index to Physical Position</code> represents the LED's physical <code>{ x, y }</code> position on the keyboard. The default expected range of values for <code>{ x, y }</code> is the inclusive range <code>{ 0..224, 0..64 }</code>. This default expected range is due to effects that calculate the center of the keyboard for their animations. The easiest way to calculate these positions is imagine your keyboard is a grid, and the top left of the keyboard represents <code>{ x, y }</code> coordinate <code>{ 0, 0 }</code> and the bottom right of your keyboard represents <code>{ 224, 64 }</code>. Using this as a basis, you can use the following formula to calculate the physical position:</p><div class="language-c vp-adaptive-theme"><button title="Copy Code" class="copy"></button><span class="lang">c</span><pre class="shiki shiki-themes github-light github-dark vp-code"><code><span class="line"><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;">x </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">=</span><span style="--shiki-light:#005CC5;--shiki-dark:#79B8FF;"> 224</span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;"> /</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;"> (NUMBER_OF_COLS </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">-</span><span style="--shiki-light:#005CC5;--shiki-dark:#79B8FF;"> 1</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;">) </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">*</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;"> COL_POSITION</span></span>\n<span class="line"><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;">y </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">=</span><span style="--shiki-light:#005CC5;--shiki-dark:#79B8FF;"> 64</span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;"> /</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;"> (NUMBER_OF_ROWS </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">-</span><span style="--shiki-light:#005CC5;--shiki-dark:#79B8FF;"> 1</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;">) </span><span style="--shiki-light:#D73A49;--shiki-dark:#F97583;">*</span><span style="--shiki-light:#24292E;--shiki-dark:#E1E4E8;"> ROW_POSITION</span></span></code></pre></div><p>Where NUMBER_OF_COLS, NUMBER_OF_ROWS, COL_POSITION, & ROW_POSITION are all based on the physical layout of your keyboard, not the electrical layout.</p><p>As mentioned earlier, the center of the keyboard by default is expected to be <code>{ 112, 32 }</code>, but this can be changed if you want to more accurately calculate the LED's physical <code>{ x, y }</code> positions.
