+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.

+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

+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>

+/**
+ * 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
