553a94bf67 I2CManager: Refactor common driver code.
Put mux handling into I2CManager_NonBlocking.h to keep the native (controller-specific) drivers more simple.
Remove almost all but one of the static definitions, in preparation for supporting multiple I2C buses.

cb287f23a4 I2CManager: Add support for I2C Multiplexers to Wire and AVR.
AVR Native (non-blocking) driver now supports up to 8 I2C Multiplexers, as does any controller that uses Wire for I2C.
Other native drivers will be updated in due course.

13bd6ef9eb HAL: Add support for Extended Addresses and I2C Multiplexer
Change I2C addresses from uint8_t to I2CAddress, in preparation for MUX support.  Currently, by default, I2CAddress is typedef'd to uint8_t.
MUX support implemented for AVR and Wire versions.

ba9b363058 I2CManager_NonBlocking - Defer I2C speed changes for all drivers
Following on from the change to I2CManager_SAMD.h, the capability of deferring a request to change the speed of the I2C has been removed from the SAMD driver and put into the common NonBlocking code, so that all native drivers benefit from it.

Neil bugfixes. (#186)
* Re-enable native I2C driver.

* Minor non-functional changes to native I2C Manager.

* Minor changes to make variable types explicit in comparisons.

* Fix IODevice::loop() to avoid null pointer dereference.

Strange problems with LCD driver tracked down to being caused by a call to p->_loop() when p is NULL.

* Correct sense of comparison in LCN support function Turnout::setClosedStateOnly()

* Remove code (now unused) from LCD driver.

* Add I2C textual error messages.

* Add I2C textual error messages.

* Fix compile error in 4809 I2C driver.

* Remove init function call from SSD1306 driver.

ALL these changes should be portable back to master

* Remove extra timer that was already added

* Changed to EveryTimerB

* Add everytimerb.h

* Cleanup

* Linear address <a> cmd

* Allow lower case keywords

* Add the F define to be on safe side if it is not present in the library core code

* Clean simple Timer interface

Removes overkill files, puts all timer in a single small file. (DCCTimer)

* Timer port

* Timer working

And slow wave command removed

* Correcting non-portables merged from master

* Wave-state machine ( part 11)

* Microtuning waveform

Significant reduction in code paths and call overheads

* Current check cleanup

* Fix no-loco id

Has to handle -1 correctly

* fix wrong format letter

* redo flow through wifisetup again

* version++

* bugfixes wifi setup

* Retry harder for AP mode

* Remove unued if

* DIO2 replacement

Currently for writing signal pins during waveform.

* Drop analogReadFast (see DCCTimer)

AnalogRead speed set in DCCTimer for ease of porting.
Code tidy and diagnostics in MotorDriver

* UNTESTED fast power,brake,fault pins

* Distunguish between in/out of FASTPIN

* minor performance tweaks

* Config comments and example use

* Config/example loading

* IP/PORT on LCD

* Ethernet simulated mac

Plus fixed listening port

* Github SHA

* Committing a SHA

* Fix for nano compile

* Comments and a reliability fix.

* UnoRev2 protection

* PWM pin implementation

* fix wifi setup issue

* Reinstate IP_PORT

* Wifi channel and code cleaninga

* Reduce duplicated F() macros

Compiler isn't as clever as one might expect

* Committing a SHA

* Update config.example.h

Add comment to wifi channel section

* Committing a SHA

* Handle shields with common fault pins (Pololu)

* Committing a SHA

* remove warning

* Committing a SHA

* only do the sha generation on master

* yaml syntax

* Fast SSD1306 OLED driver

Incorporate code from SSD1306Ascii library to speed up OLED screen updates, reduce memory requirements and eliminate some library dependences.

* Fix auto-configure from cold boot.

Add call to Wire.begin().

* Update comment for OLED_DRIVER define.

* Update MotorDrivers.h

Add a motor board definition for using the IBT_2 board for a high current to the main track and keep the Arduino Motor Shield for operating the programming track.

* Committing a SHA

* Fix missing F  in motor drivers

* JOIN relay pin

* Swap Join Relay high/low

* Hide WIFI_CONNECT_TIMEOUT

This is not what the config suggests it is...  The timeout is in the ES and defaults to 15 seconds. Abandoning it early leads to confused setup.

* Enhance OLED/LCD speed

Write one character or position command per loop entry so as not to hold up the loop.  Add support for SH1106 OLED as 132x64 size option.

* Enhance OLED/LCD speed

* Delete comment about OLED on UNO.

* Trim unwanted code

* Handle display types correctly

* Update comments

* Speed up OLED writes

Add new flushDisplay() to end any in-progress I2C transaction.  Previously, an redundant command was sent that ended the in-progress transaction but also sent another complete, but unnecessary, transaction.

* Comments and copyright update

* Reduce RAM and flash requirement a few more bytes.

* Move statics into LCDDisplay class, and reduce RAM.

Some state variables were static in LCDDisplay.write().  Moved to class members.  Also, types of data items like row, column & character position changed to int8_t to save a few bytes of RAM.

* Type lcdCols and lcdRows to unsigned.

Since lcdCols is normally 128, it needs to be uint8_t, not int8_t.

* remove timeout from user config

* faultpin is common only if it exists ; make code prettier

* Rationalisation of SSD1306 driver

Merge SSD1306AsciiWire.cpp into SSD1306Ascii.cpp and rename SSD1306AsciiWire.h as SSD1306Ascii.h.
Merge allFonts.h into System5x7.h and rename as SSD1306font.h.
Move all SSD1306 files into root folder to facilitate compilation in Arduino IDE.

* Fix some font attributes as const.

* Remove unused initialisation sequences for tiny oled screens

* Add m_ to variables

* Bump up I2C speed

Speed was 100kHz (default).  Max for OLEDis 400kHz.

This reverts commit 1c1168f433.

* Bump up I2C speed

Speed was 100kHz (default). Max for OLEDis 400kHz.

* Drop duplicate DIAG

* ignore mySetup.h files

* Restore uno to default_envs

Restore uno (previously commented out) to default_envs.

Trim unused functionality;
Reduce I2C communications to minimum;
Speed up I2C clock to 400kHz.

* Update config.example.h

Add IBT_2_WITH_ARDUINO to example config

* Update config.example.h

* Screen enhancements (#126)

* Add I2CManager to coordinate I2C shared parameters.

* Add use of I2CManager, and experimental scrolling strategies.

New scrolling capability by defining SCROLLMODE in Config.h to 0 (original), 1 (by page) or 2 (by line).  If not defined, defaults to 0.

* Scrolling updates

New scrolling capability by defining SCROLLMODE in Config.h to 0 (original), 1 (by page) or 2 (by line). If not defined, defaults to 0.
Reformat.

* Add I2CManager calls. Remove unnecessary delays.

* Add I2CManager calls, remove unnecessary I2C delays.

* SSD1306: Move methods from .h to .cpp and reformat.

* Fix compiler warning in LiquidCrystal_I2C

* Allow forcing of I2C clock speed.

New method forceClock allows the I2C speed to be overridden.  For example, if the I2C bus is long then the speed can be forced lower.  It can also be forced higher to gain performance if devices are capable.

* Make Config.h conditionally included.

Allow for non-existence of Config.h.

* Correct scrolling and allow longer messages

Correct the handling of scrolling in scrollmode 1 to avoid a blank page being displayed.  Also, allow MAX_MSG_SIZE to be optionally configured to override maximum message length on screens.

* compiler warning on uno
