 ## Music Mode
 
 The music mode maps your columns to a chromatic scale, and your rows to octaves. This works best with ortholinear keyboards, but can be made to work with others. All keycodes less than `0xFF` get blocked, so you won't type while playing notes - if you have special keys/mods, those will still work. A work-around for this is to jump to a different layer with KC_NOs before (or after) enabling music mode.

+# HD44780 LCD Displays
+
+This is an integration of Peter Fleury's LCD library. This page will explain the basics. [For in depth documentation visit his page.](http://homepage.hispeed.ch/peterfleury/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)
+
+You can enable support for HD44780 Displays by setting the `HD44780_ENABLE` flag in your keyboards `rules.mk` to yes. This will use about 400 KB of extra space.
+
+## Configuration
+
+You will need to configure the pins used by your display and its number of lines and collumn in your keyboards `config.h`.
+
+Uncomment the section labled HD44780 and change the parameters as needed.
+````
+/*
+ * HD44780 LCD Display Configuration
+ */
+
+#define LCD_LINES           2     //< number of visible lines of the display
+#define LCD_DISP_LENGTH    16     //< visibles characters per line of the display

+#define LCD_E_PIN        1            //< pin  for Enable line    
+#endif
+````
+
+Should you need to configure other properties you can copy them from `quantum/hd44780.h` and set them in your `config.h`
+
+## Usage 
+
+To initialize your display call lcd_init() with one of these parameters:
+````
+LCD_DISP_OFF             : display off
+LCD_DISP_ON              : display on, cursor off
+LCD_DISP_ON_CURSOR       : display on, cursor on
+LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing 
+````
+This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`.  
+It is advised to clear the display before use.  
+To do so call `lcd_clrsrc()`.
+
+To now print something to your Display you first call `lcd_gotoxy(column, line)`. To go to the start of the first line you would call `lcd_gotoxy(0, 0)` and then print a string with `lcd_puts("example string")`.
+
+There are more posible methods to control the display. [For in depth documentation please visit the linked page.](http://homepage.hispeed.ch/peterfleury/doxygen/avr-gcc-libraries/group__pfleury__lcd.html)

+ Title:     HD44780U LCD library
+ Author:    Peter Fleury <[email protected]>  http://tinyurl.com/peterfleury
+ License:   GNU General Public License Version 3
+ File:	    $Id: lcd.c,v 1.15.2.2 2015/01/17 12:16:05 peter Exp $
+ Software:  AVR-GCC 3.3 
+ Target:    any AVR device, memory mapped mode only for AT90S4414/8515/Mega
+
+ DESCRIPTION
+       Basic routines for interfacing a HD44780U-based text lcd display
+
+       Originally based on Volker Oth's lcd library,
+       changed lcd_init(), added additional constants for lcd_command(),
+       added 4-bit I/O mode, improved and optimized code.
+
+       Library can be operated in memory mapped mode (LCD_IO_MODE=0) or in 
+       4-bit IO port mode (LCD_IO_MODE=1). 8-bit IO port mode not supported.
+       
+       Memory mapped mode compatible with Kanda STK200, but supports also
+       generation of R/W signal through A8 address line.
+
+ USAGE
+       See the C include lcd.h file for a description of each function

+ @brief Basic routines for interfacing a HD44780U-based character LCD display
+
+ LCD character displays can be found in many devices, like espresso machines, laser printers. 
+ The Hitachi HD44780 controller and its compatible controllers like Samsung KS0066U have become an industry standard for these types of displays. 
+ 
+ This library allows easy interfacing with a HD44780 compatible display and can be
+ operated in memory mapped mode (LCD_IO_MODE defined as 0 in the include file lcd.h.) or in 
+ 4-bit IO port mode (LCD_IO_MODE defined as 1). 8-bit IO port mode is not supported.
+
+ Memory mapped mode is compatible with old Kanda STK200 starter kit, but also supports
+ generation of R/W signal through A8 address line.
+
+ @see The chapter <a href=" http://homepage.hispeed.ch/peterfleury/avr-lcd44780.html" target="_blank">Interfacing a HD44780 Based LCD to an AVR</a>
+      on my home page, which shows example circuits how to connect an LCD to an AVR controller.

+===
+
+A QMK-powered replacement PCB for custom TKL keyboards. This PCB has the same size of the b.87 PCB, while using the USB port placement and spacebar stabilizer orientation as the a.87 PCB.
+
+Keyboard Maintainer: hineybush (Josh Hinnebusch)  
+
+Hardware Supported: h87a Rev 1  
+
+Hardware Availability: Currently prototyped, group buy TBD  
+
+Make example for this keyboard (after setting up your build environment):
+     
+     make h87a:default
+   
+## h87a hardware information
+
+Controller: Atmega32u4
+
+    /* Column pin configuration
+    * col: 0   1   2   3   4   5   6   7   8   
+    * pin: F0  F1  F4  F5  F6  F7  C7  C6  D2
+    */

+    * pin: B0  B1  B2  B3  D0  D1  B5  B6  D7  B4  D6  D4  (Rev 1)
+    */
+    
+The H87a PCB utilizes duplex matrix organization.
+
+    Caps Lock LED: D5
+    Scroll Lock LED: E6
+    Num Lock LED: not supported
+    Backlight Pin: B7
+    RGB Data Pin: D3
+    
+To connect the Caps Lock LED to the main backlight matrix, jump the middle pad and the left pad on J1. To use the Caps Lock LED as an indicator, jump the middle pad and the right pad on J1.

+    - this'll reduce work load of assembly
+
+- move rn42 to protocol directory when it becomes reusable stack
+
+- sendchar() in lufa.c no buffer
+    - no buffering. character lost can be caused.
+- LUFA sendchar should be buffered and serial_uart.c buffur size is too large(256).

+- HHKB matrix.c needs matrix_prev?
+    - is_modified() is obsolete now. really needs?
+- ADC: removing AREF capacitor C10
+    - seems to be better while usb powered
+    - still bad while battery powered
+    http://electronics.stackexchange.com/questions/105849/avcc-and-capacitor-using-adc
+- ADC: smaller resistors for voltage dividor
+    - 1K + 1K: not improved. - 11/27

+TROUBLE SHOOT
+-------------
+07/16   After fix of voltage dividor on GPIO6, had a trouble that it could not send a char to BT module, though could receive.
+        Found R8 had wrong 1K resistor and changed to 10K, after that it can send to the module again. Not sure how it had sent with the wrong 1K before.
+
+07/18   On Linux, had an USB related trouble; keyboard or console didn't work for some reason. Changing PID cured this problem. Very annoying, took very long time before resolved it.
+
+12/07   rn42_rts() read 1 every time. R12 broke in open mode(no coductive), idk why, too much heat with soldering? and PF1 pin was not soldered.
+        It resolved with resoldering PF1 and new resistor on R12.
+
+

+            780mV is still low < 1.4V VBUS plugin detection(21.11)
+                this doesn't cause false VBUS detect
+                and 780mV on MCP73832 Vcc pin is also no problem.
+            D5 can be removed.

+RN-42 Bluetooth Module Support
+==============================
+Bluetooth controller board works with HHKB Pro2, JP, Type-S and Type-S JP and it supports both USB and Bluetooth as keyboard output protocol. Bluetooth module Roving Networks/Microchip RN-42 is installed on the board.
+
+
+RN-42:
+http://www.microchip.com/wwwproducts/Devices.aspx?product=RN42
+
+
+Capabitlities:
+- USB keyboard functions
+    completely equivarent to USB controller including mouse keys and NKRO.
+- Switching between USB and Bluetooth
+    You can switch the two connections with BT switch or key combination.
+- RN-42 config mode
+    You can change power/connection configuration of the module if needed.
+- Low battery alert
+    Red LED turns on when low voltage.
+- RN-42 status indicator
+    LED indicates status of Bluetooth connection.
+- Pairing
+    The module stores up to 8 connections.
+- Auto connect
+    The module connects the last connected device automatically.
+- iOS support
+    works as keyboard with iPhone5. No tested completely.
+- Android support
+    works as keyboard and mouse with Nexus5. No tested completely.
+- Mouse keys over BT
+    Note that iOS doesn't accept mouse device.
+
+
+Limitations:
+- Short battery life
+    Around 12hr with 1000mAh
+- No connection switching
+    RN-42 auto-connects to the last connected device.
+    Some of consumer products can switch between devices, for example Logitech K480.
+        http://www.logitech.com/en-us/product/multi-device-keyboard-k480?crid=26
+- HHKB JP requires case modification for BT switch and LEDs.
+    without switch power controlled by MCU? Probably using 3.3V regulator enable pin power of RN-42 can be controlled.
+
+NOTE:
+- LIPO BATTERY IS VERY DANGEROUS, TAKE EXTRA CARE OF YOUR SAFETY AND PROPERTY.
+- RN-42 version 6.15 is supported.
+- No NKRO over Bluetooth
+- Check you country's wiress regulation and certification of RN-42.

+
+
+Operation Modes
+---------------
+SM,3        Auto Connect Master mode
+SM,4        Auto Connect DTR Mode uses GPIO6 to make and break connection(Mode =DTR)
+                confirm: auto connect works and control connection with GPIO6
+SM,5        Auto Connect ANY Mode (Mode =ANY)
+                each time GPIO is set, make inquiry and connect to the first found device
+SM,6        automatically reconnect(Mode =Pair)
+                confirm: auto connect works well but difficult to enter command mode.

+Apple iOS
+---------
+Keyboard can be used with iPhone, but mouse cannot.
+
+
+Android
+-------
+3.7.1.5 Note: To connect with Android phone the modules must wake up 11ms every 2.5seconds.
+
+
+Power Management
+----------------
+Inquiry and Page window     Idle or Active  (3.1.1)
+    Downside: delay in discovery or connection time
+    SI,         // set inquiry scan window(discovery) on/off duty?
+    SJ,         // set page scan window(connection)
+    This reduces averaege power >20mA to 5mA(3mA in Sniff mode)
+
+Sniff mode                  Transmit
+    Sniff mode is disabled by default and radio is active continuously when connected.(25-30mA)
+    In Sniff mode the radio wakes up intermittently and sleeps in very low power mode.(2mA)
+    SW,<val>    // set interval timer(*0.625ms) 0000-7FFF
+
+Deep sleep                  Idle            (3.1.2)
+    In this mode the module shuts down completly and only draws about 300uA. To enable this set the most signifant bit(0x8000) of Sniff interaval timer.
+    SW,8320     // deep sleep enable(interval=0x320*0.625=500ms)
+    In normal sleep the firmware is still running in idle mode, and wakes up about 20 times per second to check ports, update LEDs, etc. During deep sleep, the firmware actually stops runnig some tasks and the LEDs only update about once per second.
+    To wake from deep sleep there are three ways: (in worst case wake up takes 5ms)
+        *send a charactor to the UART(first charactor will be lost)
+        *toggle CTS low to high and wait 5ms
+        *wake automatically every slot time(<val>*0.625ms)
+    Once the radio is awake it stay active for exactly 1 second of inactivity and then sleeps again.
+    Downside: latency and data loss
+
+Disable Output driver       Idle or Active  (3.1.3)
+    S%,1000     // set all GPIO pins(0-11) to inputs.
+
+Lower Transmit Power        Idle or Active  (3.1.4)
+    SY,<hex>    // transmit power setting(takes effect after a power cycle and reboot)
+    Downside: reducing effective range
+
+
+Optimizig for Latency
+---------------------
+By default the firmware is optimized for throughput.
+SQ,16           // set latency bit
+SQ,0            // unset latency bit
+
+
+Configuration timer settings
+----------------------------
+Remote configuration is used for the module to be configured with various commands over Bluetooth(SPP profile only?).
+
+The module has remote configuration timer to allow remote configuration over Bluetooth after power up in Slave mode. In Master modes the remote configuration timer is set to 0(no remote configuration). (In Trigger Master mode the timer is used as an idle timer to break the connection after time expires with no charactors receive.)
+    ST,0        // no remote, no local when connected
+    ST,<1-252>  // local and remote with timeout in seconds from power up
+    ST,253      // local only       without timeout
+    ST,254      // remote only      without timeout
+    ST,255      // local and remote without timeout
