Most features(TX, Frequency Range, Ham Band, TX Control, CW delay, start Delay... more) have been added by KD8CEC.

However, the license rules are subject to the original source rules.

* This verision uses a built-in Si5351 library
|
|
* Most source code are meant to be understood by the compilers and the computers.
|
|
* Code that has to be hackable needs to be well understood and properly documented.
|
|
* Donald Knuth coined the term Literate Programming to indicate code that is written be
|

|
|
*
|
|
* The Raduino is a small board that includes the Arduin Nano, a 16x2 LCD display and
|
|
* an Si5351a frequency synthesizer. This board is manufactured by Paradigm Ecomm Pvt Ltd
|
|
*
|
|
* 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
|
|
* repeatedly keeps calling loop() forever. All the initialization code is kept in setup()
|
|
* 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
|
|
* to the bottom of this file and read your way up.
|
|
*
|
|
* Below are the libraries to be included for building the Raduino
|
|
* The EEPROM library is used to store settings like the frequency memory, caliberation data,
|
|
* callsign etc .
|
|
*
|
|
* The main chip which generates upto three oscillators of various frequencies in the
|
|
* Raduino is the Si5351a. To learn more about Si5351a you can download the datasheet
|
|
* from www.silabs.com although, strictly speaking it is not a requirment to understand this code.
|
|
* Instead, you can look up the Si5351 library written by xxx, yyy. You can download and
|
|
* install it from www.url.com to complile this file.
|
|
* The Wire.h library is used to talk to the Si5351 and we also declare an instance of
|
|
* Si5351 object to control the clocks.

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

* The uBITX is an upconnversion transceiver. The first IF is at 45 MHz.
|
|
* The first IF frequency is not exactly at 45 Mhz but about 5 khz lower,
|
|
* 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 12 Mhz has a ladder crystal filter. If a second oscillator is used at
|
|
* 57 Mhz, the signal is subtracted FROM the oscillator, inverting a second time, and arrives
|
|
* at the 12 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

|

* - When KT1 is ON, it routes the PA output to KT2. Which is why you will see that

* - When the KT1 is ON and KT2 is off, the off position of KT2 routes the PA output

* to 18 MHz LPF (That also works for 14 Mhz)
|
|
* - When KT1 is On, KT2 is On, it routes the PA output to KT3
|
|
* - KT3, when switched on selects the 7-10 Mhz filter
|
