Code
In this page I will show the different codes I did to manage the electronics and the interface created for this project, everything was coded in Arduino C code and Processing.
Arduino Codes
I had to program 2 different boards for this project, the fret boards and the master board. As I explained in Networking Week, I decided to connect them with I2C through a ribbon cable, because it is easier and faster than a wireless connection. Then, between Ukuleles I decided to use Bluetooth to communicate them via serial port. This allows the two Ukuleles to talk without being connected making it more comfortable for the players. For this reason, I have 3 different codes, 1 for the slave boards and 2 for the master's boards, one for the teacher's ukulele and one for the student. In the future I will make the same code for the 2 master boards, but I didn't had the time. Let's check the code.
Codification message
First, before explaining the codes I made, I would like to explain how the communication works, how the frets are represented and how they codify the information. The communication is via I2C between boards and serial between devices, can be Bluetooth or the FTDI cable, but always using the serial protocol. Then, all the communication is made by reading and writing bytes, so I decided to codify the messages that I needed to send to send the less bytes possible and avoid errors. After some tests and talking with Oscar, I decided to send one byte for each fret, and that byte will say which fret I'm reading and the status of it. Knowing that the fret are 4 buttons or LED's with two possible states each (High or Low), with 4 bits I could represent all the possible states. That leaves us 4 more bits to represent the fret that we are representing. Finally we decided to use the first four bits for the fret number and the last 4 for the state of the fret.
This codification was a great improvement, because with other tests I had some problems reading strings or integers, sending bytes make the job much more easy and avoid any possible error. During Week 8, I had the opportunity to learn about bit operation studying C code, and that was really useful for making a optimized code.
Master's board
Teacher Ukulele
This is the code for the teacher master board, and it have two functions. It starts waiting for a byte from the connected device through the serial. This byte can be the 'r' character or the 'w' character, for reading or writing. If it receives an 'r' it reads the state of the frets, that act like an input board in this case, with the I2C communication and send back this state to the connected device. Otherwise, if it receives an 'w' it waits until it receives the desired state and then send them to the frets as outputs, to light up. This is the code:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(8, 7);
#include
String mode = "";
int Dev[] = {1, 2, 3, 4, 5};
int nDev = 5; //Change this number accordingly to the number of devices
int State[] = {0, 0, 0, 0, 0};
int PrevState[] = {0, 0, 0, 0, 0};
void setup() {
Wire.begin(); // join i2c bus (address optional for master)
mySerial.begin(9600); // start serial for output
delay(5000);
}
void loop() {
while (mySerial.available() == 0) {}
if (mySerial.available() > 0) {
mode = mySerial.readStringUntil('\n');
//mySerial.println(mode);
}
if (mode == "r") {
readU();
}
if (mode == "w") {
writeU();
}
}
void readU() {
for (byte i=0; i < nDev; i++) {
Wire.requestFrom(Dev[i],1);
while (Wire.available()){
byte state = Wire.read();
byte message = Dev[i] << 4;
message = message | state;
mySerial.write(message);
}
}
}
void writeU() {
while (mySerial.available() == 0) {}
for (byte i=0; i < nDev; i++) {
byte m = mySerial.parseInt();
Wire.beginTransmission(Dev[i]);
Wire.write(m);
Wire.endTransmission();
}
} Student Ukulele
This code was made for the Student's Ukulele and it can only receive the desired state and it write it to the frets. This was a easy solution, but I will try to make a generic code for both and use the slide switch to switch between modes, so the student can also show the teacher. It is really simple, it just send an 'r' character to the other master to read it's state and then light's up accordingly.
#include
SoftwareSerial mySerial(8, 7);
#include
String mode = "";
int Dev[] = {1, 2, 3, 4, 5};
int nDev = 5; //Change this number accordingly to the number of devices
int State[] = {0, 0, 0, 0, 0};
int PrevState[] = {0, 0, 0, 0, 0};
byte lec;
void setup() {
Wire.begin(); // join i2c bus (address optional for master)
mySerial.begin(9600); // start serial for output
delay(5000);
}
void loop() {
mySerial.write("r");
mySerial.write('\n');
while (mySerial.available() > 0) {
lec = mySerial.read();
Wire.beginTransmission(int(lec >> 4));
Wire.write(int(lec & 15));
Wire.endTransmission();
}
delay(100);
} Fret Boards
This code is generic and optimized for each fret, the only change you need to do is change the address number to the fret number you want it to be. This was the first time I used bit shifting and it felt like being in heaven, I was able to go from more than 100 lines of code to 2 lines. There I realized that learning C code could be a great improvement. This code is super simple, it only reads swipe from input or output depending on the Masters action, if it request the state it read the input buttons, if it sends the state it write the output LED's.
#include
byte pins = 0b00000000;
void setup() {
Wire.begin(5);
Wire.onReceive(receiveEvent);
Wire.onRequest(requestEvent);
}
void loop() {
//delay(100);
}
void receiveEvent(int howMany) {
DDRA = DDRA | B00001111;
pins=Wire.read();
PORTA = ((PORTA>>4)<<4)|pins;
}
void requestEvent() {
PORTA = ((PORTA>>4)<<4);
DDRA &= ~B00001111;
Wire.write(PINA & (B00001111));
} Processing
I decided to create an interface for the Ukulele during Interface and application programming Week with Processing. You can find all the documentation in this week page, but I will explain here what it does and the latest features.
In big terms, this interface have 2 different purposes, show what you are plying and show you how to play the chords. I created a chord library with the main chords to practice and learn it in a easy way. The interface present a ukulele that lights up like the prototype and some buttons to chose the different options.
After having the first version, I decided to go a little bit further, and I get the processing interface to create MIDI notes while you are plying using the MidiBus library, so now, you can connect the Ukulele to the computer using an FTDI cable and create digital music notes that then could be processed with professional softwares like Ableton for example to create electronic music.
This is the code:
