Refactored code 

The files are not split into .cpp and .h files. The main file ubitxxxx.cpp will have the main routines to control the radio, initialization and main loop. The user interface is implemented in ubitx_ui.cpp, the code for setup/calibration routines is in setup.cpp. Nano gui, keyer, morse.cpp (morse reader) are all libaries that have minimum dependencies on each other.

/**
CW Keyer
CW Key logic change with ron's code (ubitx_keyer.cpp)
Ron's logic has been modified to work with the original uBITX by KD8CEC
Original Comment ----------------------------------------------------------------------------
* The CW keyer handles either a straight key or an iambic / paddle key.
* They all use just one analog input line. This is how it works.
* The analog line has the internal pull-up resistor enabled.
* When a straight key is connected, it shorts the pull-up resistor, analog input is 0 volts
* When a paddle is connected, the dot and the dash are connected to the analog pin through
* a 10K and a 2.2K resistors. These produce a 4v and a 2v input to the analog pins.
* So, the readings are as follows :
* 0v - straight key
* 1-2.5 v - paddle dot
* 2.5 to 4.5 v - paddle dash
* 2.0 to 0.5 v - dot and dash pressed
*
* The keyer is written to transparently handle all these cases
*
* Generating CW
* The CW is cleanly generated by unbalancing the front-end mixer
* and putting the local oscillator directly at the CW transmit frequency.
* The sidetone, generated by the Arduino is injected into the volume control

/** Menus
* The Radio menus are accessed by tapping on the function button.
* - The main loop() constantly looks for a button press and calls doMenu() when it detects
* a function button press.
* - As the encoder is rotated, at every 10th pulse, the next or the previous menu
* item is displayed. Each menu item is controlled by it's own function.
* - Eache menu function may be called to display itself
* - Each of these menu routines is called with a button parameter.
* - The btn flag denotes if the menu itme was clicked on or not.
* - If the menu item is clicked on, then it is selected,
* - If the menu item is NOT clicked on, then the menu's prompt is to be displayed

* The uBITX is an upconnversion transceiver. The first IF is at 45 MHz.

* this shift is due to the loading on the 45 Mhz crystal filter by the matching
* L-network used on it's either sides.
* The first oscillator works between 48 Mhz and 75 MHz. The signal is subtracted
* from the first oscillator to arriive at 45 Mhz IF. Thus, it is inverted : LSB becomes USB
* and USB becomes LSB.
* The second IF of 11.059 Mhz has a ladder crystal filter. If a second oscillator is used at
* 56 Mhz (appox), the signal is subtracted FROM the oscillator, inverting a second time, and arrives
* at the 11.059 Mhz ladder filter thus doouble inversion, keeps the sidebands as they originally were.
* If the second oscillator is at 33 Mhz, the oscilaltor is subtracated from the signal,
* thus keeping the signal's sidebands inverted. The USB will become LSB.
* We use this technique to switch sidebands. This is to avoid placing the lsbCarrier close to
* 11 MHz where its fifth harmonic beats with the arduino's 16 Mhz oscillator's fourth harmonic

// ************* SI5315 routines - tks Jerry Gaffke, KE7ER ***********************
// An minimalist standalone set of Si5351 routines.
// VCOA is fixed at 875mhz, VCOB not used.
// The output msynth dividers are used to generate 3 independent clocks
// with 1hz resolution to any frequency between 4khz and 109mhz.
// Usage:
// Call si5351bx_init() once at startup with no args;
// Call si5351bx_setfreq(clknum, freq) each time one of the
// three output CLK pins is to be updated to a new frequency.
// A freq of 0 serves to shut down that output clock.
// The global variable si5351bx_vcoa starts out equal to the nominal VCOA
// frequency of 25mhz*35 = 875000000 Hz. To correct for 25mhz crystal errors,
// the user can adjust this value. The vco frequency will not change but
// the number used for the (a+b/c) output msynth calculations is affected.
// Example: We call for a 5mhz signal, but it measures to be 5.001mhz.
// So the actual vcoa frequency is 875mhz*5.001/5.000 = 875175000 Hz,
// To correct for this error: si5351bx_vcoa=875175000;
// Most users will never need to generate clocks below 500khz.
// But it is possible to do so by loading a value between 0 and 7 into
// the global variable si5351bx_rdiv, be sure to return it to a value of 0
// before setting some other CLK output pin. The affected clock will be
// divided down by a power of two defined by 2**si5351_rdiv
// A value of zero gives a divide factor of 1, a value of 7 divides by 128.
// This lightweight method is a reasonable compromise for a seldom used feature.

*
* To learn more about Arduino you may visit www.arduino.cc.
*
* The Arduino works by starts executing the code in a function called setup() and then it

* and code to continuously sense the tuning knob, the function button, transmit/receive,
* etc is all in the loop() function. If you wish to study the code top down, then scroll

We no longer use the standard SI5351 library because of its huge overhead due to many unused
features consuming a lot of program space. Instead of depending on an external library we now use
Jerry Gaffke's, KE7ER, lightweight standalone mimimalist "si5351bx" routines (see further down the
code). Here are some defines and declarations used by Jerry's routines:

/**
* We need to carefully pick assignment of pin for various purposes.
* There are two sets of completely programmable pins on the Raduino.
* First, on the top of the board, in line with the LCD connector is an 8-pin connector
* that is largely meant for analog inputs and front-panel control. It has a regulated 5v output,
* ground and six pins. Each of these six pins can be individually programmed
* either as an analog input, a digital input or a digital output.
* The pins are assigned as follows (left to right, display facing you):
* Pin 1 (Violet), A7, SPARE
* Pin 2 (Blue), A6, KEYER (DATA)
* Pin 3 (Green), +5v
* Pin 4 (Yellow), Gnd
* Pin 5 (Orange), A3, PTT
* Pin 6 (Red), A2, F BUTTON
* Pin 7 (Brown), A1, ENC B
* Pin 8 (Black), A0, ENC A
*Note: A5, A4 are wired to the Si5351 as I2C interface
* *
* Though, this can be assigned anyway, for this application of the Arduino, we will make the following
* assignment
* A2 will connect to the PTT line, which is the usually a part of the mic connector
* A3 is connected to a push button that can momentarily ground this line. This will be used for RIT/Bandswitching, etc.
* A6 is to implement a keyer, it is reserved and not yet implemented
* A7 is connected to a center pin of good quality 100K or 10K linear potentiometer with the two other ends connected to
* ground and +5v lines available on the connector. This implments the tuning mechanism
