# Basic I/O Instruments G60
 
![BIOI G60](https://raw.githubusercontent.com/yilihong/alf/gh-pages/assets/img/g60/g60_gb/1.jpg)

Inspired by the design of the Cherry G80 series, the G60 is a 60% USB/Bluetooth dual-mode custom keyboard.

* Keyboard Maintainer: [Basic I/O Instruments (Scott Wei)](https://github.com/scottywei)
* Hardware Supported: [BIOI G60BLE PCB](https://scottywei.github.io/bioi-g60ble/)
* Hardware Availability: [BIOI Taobao Store](https://item.taobao.com/item.htm?&id=611933113439) / [Playkeyboard](https://play-keyboard.store/products/bioi-g60ble-pcb-default-version-custom-60-bluetooth-pcb)

Make example for this keyboard (after setting up your build environment):

    make bioi/g60:default

See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

Changelog for modifications made by Tim Sharpe, starting with the current
  library version on his Web site as of 05/01/2009.

Date        Description
=========================================================================
05/11/2009  Changed all existing UARTx_RECEIVE_INTERRUPT and UARTx_TRANSMIT_INTERRUPT
			macros to use the "_vect" format introduced in AVR-Libc
			v1.4.0.  Had to split the 3290 and 6490 out of their existing
			macro due to an inconsistency in the UART0_RECEIVE_INTERRUPT
			vector name (seems like a typo: USART_RX_vect for the 3290/6490
			vice USART0_RX_vect for the others in the macro).
			Verified all existing macro register names against the device
			header files in AVR-Libc v1.6.6 to catch any inconsistencies.
05/12/2009  Added support for 48P, 88P, 168P, and 328P by adding them to the
			existing 48/88/168 macro.
			Added Arduino-style available() and flush() functions for both
			supported UARTs.  Really wanted to keep them out of the library, so
			that it would be as close as possible to Peter Fleury's original
			library, but has scoping issues accessing internal variables from
			another program.  Go C!
05/13/2009  Changed Interrupt Service Routine label from the old "SIGNAL" to
			the "ISR" format introduced in AVR-Libc v1.4.0.

 * 
 *  @brief Interrupt UART library using the built-in UART with transmit and receive circular buffers.
 *  @see README.md
 *
 *  This library can be used to transmit and receive data through the built in UART. 
 *
 *  An interrupt is generated when the UART has finished transmitting or
 *  receiving a byte. The interrupt handling routines use circular buffers
 *  for buffering received and transmitted data.
 *
 *  The UART_RXn_BUFFER_SIZE and UART_TXn_BUFFER_SIZE constants define
 *  the size of the circular buffers in bytes. Note that these constants must be a power of 2.
 *
 *  You need to define these buffer sizes as a symbol in your compiler settings or in uart.h
 *
 *  See README.md for more detailed information. Especially that relating to symbols: USARTn_ENABLED and USARTn_LARGE_BUFFER
 *
 *  @author Andy Gock <andy@gock.net>
 *  @note Based on Atmel Application Note AVR306 and original library by Peter Fleury and Tim Sharpe.
