#KC4UPR'S NOTE
#IMPORTANT INFORMATION
----------------------------------------------------------------------------
This is a fork of the KD8CEC firmware that will be specific to my uBITX V5
installation. My intent is to remove unnecessary code, as well as make some
GPIO changes based on my use of the Nextion LCD. Specifically, I'd like to
eliminate the use of analog I/O for reading the CW keys, and possibly enable
control of accessories such as filters using the extra GPIO pins that are
now available.
- Beta 0.26 and Beta 0.261, Beta 0.262, Beta 0.27 is complete test
- You can download and use it.
#NOTICE
----------------------------------------------------------------------------
- Now Release Version 1.20 on my blog (http://www.hamskey.com)
- You can download and compiled hex file and uBITX Manager application on release section (https://github.com/phdlee/ubitx/releases)
- For more information, see my blog (http://www.hamskey.com)
I received uBITX a month ago and found that many features are required, and began coding with the idea of implementing minimal functionality as a general hf transceiver rather than an experimental device.
- fixed bugs...
- Diallock for uBITX's sensitive encoders
- built in softare Memory keyer and cw options control for CW communication
- Implementation of CAT communication protocol for Digital Communication (as FT8, JT65, etc)
- Delay Options for external Linear.
- and more...
Most of the basic functions of the HF transceiver I thought were implemented.
The minimum basic specification for uBITX to operate as a radio, I think it is finished.
So I will release the 0.27 version and if I do not see the bug anymore, I will try to change the version name to 1.0.
Now uBITX is an HF radio and will be able to join you in your happy hams life.
Based on this source, you can use it by adding functions.
I am going to do a new project based on this source, linking with WSPR, WSJT-X and so on.
Of course, this repository is still running. If you have any bugs or ideas, please feel free to email me.

----------------------------------------------------------------------------
Prepared or finished tasks for the next version
- Add TTS module
- Direct control for Student
- Most of them are implemented and included in version 0.27.
- User Interface on LCD -> Option by user (not need)
- Include WSPR Beacone function - (implement other new repository)
complete experiment
need solve : Big code size (over 100%, then remove some functions for experment)
need replace Si5351 Library (increase risk and need more beta tester)
W3PM sent me his wonderful source - using BITX, GPS

This file will guide you to change the source code file.
For Windows-based Arduino IDE users, the directory name and the Main source file name must be the same.
You do not need to learn github to download .hex files or source code that I release.
However, if you want to see what I'm doing right now, you should use the github homepage.
You do not need to learn git to suggest source code. If you give me an e-mail, I will correct it at any time.
If you have not joined the BITX Group, join group. There will be discussions on various topics every day.
I am getting a lot of hints from the group.

Softserial for Nextion LCD and Control MCU
KD8CEC, Ian Lee
-----------------------------------------------------------------------
It is a library rewritten in C format based on SoftwareSerial.c.
I tried to use as much as possible without modifying the SoftwareSerial.
But eventually I had to modify the code.
I rewrote it in C for the following reasons.
- Problems occurred when increasing Program Size and Program Memory
- We had to reduce the program size.
Of course, Software Serial is limited to one.
- reduce the steps for transmitting and receiving
useage
extern void SWSerial_Begin(long speedBaud);
extern void SWSerial_Write(uint8_t b);
extern int SWSerial_Available(void);
extern int SWSerial_Read(void);
extern void SWSerial_Print(uint8_t *b);
If you use Softwreserial library instead of this library, you can modify the code as shown below.
I kept the function name of SoftwareSerial so you only need to modify a few lines of code.
define top of source code
#include <SoftwareSerial.h>
SoftwareSerial sSerial(10, 11); // RX, TX
replace source code
SWSerial_Begin to sSerial.begin
SWSerial_Write to sSerial.write
SWSerial_Available to sSerial.available
SWSerial_Read to sSerial.read

Cat Suppoort uBITX CEC Version
This firmware has been gradually changed based on the original firmware created by Farhan, Jack, Jerry and others.
Since KD8CEC Version 0.29, most of the original code is no longer available.
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.

The main chip which generates upto three oscillators of various frequencies in the

from www.silabs.com although, strictly speaking it is not a requirment to understand this code.
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
