#include "config_common.h"

// This file includes example #defines to enable commonly-used functionality 
// (SPI, PWM backlight, etc.) on specific pins. Capabilities you want to include
// should be added to the config.h for your keyboard. Not all capabilities are
// shown; for example:
// I2C is not shown because the QMK defaults are sufficient for SCL on B6 and SDA on B7
// Serial communications (for split keyboards) is not shown because QMK defaults work
// for either pins A15 or B6

// If you need to change pins for PWM, SPI, I2C, or Serial communications, be aware that
// doing this may require changing the driver, channel, PAL (Pin ALternate function) mode, 
// DMA stream, and/or DMA channel.


// Bonsai C4 wires up pin A9 for Vbus sensing pin by default. For spilt keyboards, this
// can be used to determine which half of the keyboard is plugged into USB.
// For boards using Bonsai C4 merely as a reference design, the VBUS sense pin A9
// can be used for purposes other than Vbus sensing (e.g. the switch
// matrix).
//
// If A9 is needed for Vbus sensing, uncomment the line
// below. Most keyboards using Bonsai C4 can leave the line below
// commented out.
