Prevent loop2 from doing anything when lcdDisplay not set up. If there's a display configured but not one attached, then the OLED code will set lcdDisplay to null and no display will be configured or used by the loop() function. However, because of the way the initialisation code works, loop2() is called during initialisation.
Split update from read value;
Inhibit interrupts when reading (normally done from loop code);
Don't inhibit interrupts when updating (normally done from interupt code);
Make freeMemory() local and ask for inline code generation.
By defining ENABLE_LOOP_MEASUREMENT as true in config.h, the loop measurement will be enabled. This measures the time between successive executions of the main CS loop to help identify if something is taking too long and holding up the other loop functions.
Add function to maintain a minimum value seen of free memory. Add call to it in DCCWaveform interrupt handler (assumed to be the likely worst case for stack usage). Report this minimum value in main loop.

* 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.
* Revert "Bump up I2C speed"
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.
* Update objdump.bat
Allows other editors as Notepad is very slow on large files
* Prog Track overload during cv read

Extract LCD driver from library;
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
