-#IMPORTANT INFORMATION
+#KC4UPR'S NOTE
 ----------------------------------------------------------------------------
- Beta 0.26 and Beta 0.261, Beta 0.262, Beta 0.27 is complete test
- You can download and use it.
+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.

 #NOTICE
 ----------------------------------------------------------------------------
-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.
+- 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)

+For Windows-based Arduino IDE users, the directory name and the Main source file name must be the same.

+-----------------------------------------------------------------------
+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

+ * 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 => Analog S-Meter
+ *      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
