Raw Blame History

//Firmware Version
//+ : This symbol identifies the firmware.
// It was originally called 'CEC V1.072' but it is too long to waste the LCD window.
// I do not want to make this Firmware users's uBITX messy with my callsign.
// Putting one alphabet in front of 'v' has a different meaning.
// So I put + in the sense that it was improved one by one based on Original Firmware.
// This firmware has been gradually changed based on the original firmware created by Farhan, Jack, Jerry and others.

/**
Cat Suppoort uBITX CEC Version
This firmware has been gradually changed based on the original firmware created by Farhan, Jack, Jerry and others.
Most features(TX, Frequency Range, Ham Band, TX Control, CW delay, start Delay... more) have been added by KD8CEC.
My wish is to keep the original author's Comment as long as the meaning does not change much, even if the code looks a bit long.

Original source comment -------------------------------------------------------------
* This source file is under General Public License version 3.
*
* 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
* easily read and understood.
*
* 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.

/**
* 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
* 12 MHz where its fifth harmonic beats with the arduino's 16 Mhz oscillator's fourth harmonic

* (same line as CW, so it would be caught by cwKeyer() in CW mode).
*
* Only check the CW keyer if we are in one of the CW modes. Why? Because we
* are using the same input for PTT and CW.
