Heatmap effect may not light up the correct adjacent LEDs for certain key matrix layout such as split keyboards. The following define will limit the effect to pressed keys only:
As heatmap uses the physical position of the leds set in the g_led_config, you may need to tweak the following options to get the best effect for your keyboard. Note the size of this grid is `224x64`.
Limit the distance the effect spreads to surrounding keys.
```c
#define RGB_MATRIX_TYPING_HEATMAP_SPREAD 40
```
Limit how hot surrounding keys get from each press.
```c
#define RGB_MATRIX_TYPING_HEATMAP_AREA_LIMIT 16
```
Remove the spread effect entirely.
```c
#define RGB_MATRIX_TYPING_HEATMAP_SLIM
