Week 15
- Adjust the position of keys
- Save the performance records in the music library
- VGA
- Support switching between three basic modes and one advanced mode (free mode, automatic performance mode, learning mode and recording music mode) by using the small white keys at the bottom of EGO1.
- 【bonus】The VGA can show the mode number and name on the screen.
- Free Mode
(1). Pressing the corresponding keys will produce the corresponding notes and light the corresponding lightsPress any switches and the electronic keyboard will play the corresponding 7 notes: do, re, mi, fa, so, la, xi.
(2). Using the switches 'tone up', 'tone down' to adjust note: pressing a specific key can pop up notes to higher octaves or lower octaves.
(3). 【bonus】Users can adjust the position of keys according to their usage habits. 4. Aotomatic performance Mode
(1). We added three musics to the library and the learning machine can automatically play songs and switch to play these three songs.
(2). The user can also pause and restart at any time of palying the songs.
(3). 【bonus】We explored different various rhythm of music in the third song 春よ、来い , which has 17 different notes in different tone, and for different time interval in rhythm.
(4). We display track number on the seven digital tubes, so users can flipp back and forth through buttons. The seven segment digital tube displays the content of the music library by its number, for example, 'no.1'.
(5). During automatic performance, the lights will indicate the song's playing position and duration: When a note appears, the light will be lit above the note, and after the note is played, the light will be turned off until the song ends.
(6). 【bonus】The VGA can show the song's number and name on the screen. 5. Learning mode
(1). According to the order and duration of the notes, the LED light above the piano keys will light up to guide the user to play correctly. After the user turns on the corresponding key, the LED light will go out, and then the other light corresponding to the next note will be lit.
(2). Based on the user's performance status, display the rating of the user's performance level on a seven segment digital tube or LED light.
(3).【bonus】Teal-time changes in ratings are provided based on the difference between the user's button time and the standard time. When the difference is greater than 25000000 ns, the grade will decrease by one.
(4). We create accounts for at least three users and after a new play, the user can clinck confirm button to update his ratings based on his new performance records. 6. Recoring music mode
(1). 【bonus】For user performance records, user can choose whether to save them in the music library. The saved content will include the tone and the time interval. After pressing the confirm button, the user saves it in the device. After pressing the replay button, the user can replay it.

In top module, the VGA can show the mode number and name on the screen. In Auto performance mode, the VGA can show the song number and name on the screen.
- We use normal picture ended with '.png' or '.jpg' to transform into '. bmp' and constrain its format to 300*200, 24bit.
- We use the application program
BMP2Mifto generate the.coefiles of these pictures. - In the IP Catalog, we use
Clocking Wizardto form a 25MHz clock. - In the IP Catalog, we use
Block Memory Generatorto generator these coe file. Where we chooseSingle Port ROMasMemory Type,Port A Depthis300*200=60000.Enable PortType isAlways Enable. Finally useLoad init Fileto find the coe file.

Users can adjust the position of keys according to their usage habits.
if(~adjust_mode) begin//reset addr addr<=4'b0001; //control the tone pre_pulse1<=now_pulse1; now_pulse1<=key1_pulse; pre_pulse2<=now_pulse2; now_pulse2<=key2_pulse; pre_pulse3<=now_pulse3; now_pulse3<=key3_pulse; if(~pre_pulse2 & now_pulse2) begin if(cnt>4'b0011) cnt<=cnt-4'b1; else cnt<=cnt; end else if(~pre_pulse1 & now_pulse1) begin if(cnt<4'b0101) cnt<=cnt+4'b1; else cnt<=cnt; end else begin cnt<=cnt; end end else begin pre_pulse3<=now_pulse3; now_pulse3<=key3_pulse; real_notes[addr]<=point; if(~pre_pulse3 & now_pulse3)//confirm this node begin addr<=addr+1'b1; end else addr<=addr; end end

We explored different various rhythm of music in the third song
春よ、来い, which has 17 different notes in different tone, and 4 different time interval in rhythm.
-
Real-time changes in ratings are provided based on the difference between the user's button time and the standard time. When the difference is greater than 25000000 ns, the grade will decrease by one. We use
counter_deductto record the time out of range.if(counter_beat>=allnote[state][1]) begin light<=7'b0000000; if (note[allnote[state][0]-1]) begin if(counter_deduct<50000000) begin counter_deduct<=counter_deduct+1'b1; end else begin if(grade>0)grade<=grade-1'b1; else grade<=grade; counter_deduct<=0; end end

For user performance records, user can choose whether to save them in the music library. The saved content will include the tone and the time interval. After pressing the confirm button, the user saves it in the device. After pressing the replay button, the user can replay it.
reg [31:0] recorded_data[MAX_RECORD_LENGTH:0][1:0];
// store the music if(~save) begin pre_play <= now_play; now_play<=play; if(state!=MAX_RECORD_LENGTH) begin case(play) 7'b1000000: begin recorded_data[state][0]<=1; light <= 7'b1000000; end // ...... // same as above case default: begin light <= 7'b0000000; end endcase // last time if(pre_play==now_play) begin counter_beat<=counter_beat+1'b1; if(point>0&counter<notes[point]) begin counter<=counter+1'b1; end else begin pwm=~pwm; counter<=0; end end else begin pwm<=1'b0; recorded_data[state][1]<=counter_beat; state <= state+1; counter_beat<=0; end end end
// read the music else begin if(~pre_replay & now_replay) start<=~start; else start<=start; if(~start) begin light<=7'b0000000; counter<=0; counter_beat<=0; state<=0; counter_stop<=0; start = 1'b1; end else begin if(state<=max_state) begin case(recorded_data[state][0]) // light...... default: light <= 7'b0000000; endcase if(counter_beat<recorded_data[state][1]) begin counter_beat<=counter_beat+1'b1; if(recorded_data[state][0]>0&counter<notes[recorded_data[state][0]]) begin counter<=counter+1'b1; end else begin pwm=~pwm; counter<=0; end end else begin pwm<=0; state <= state+1'b1; counter_beat<=0; end end end

Creative idea:
(1).In the free playback module, we have realized the pausing and continuing playing of songs for the needs of users.
pre_pulse1<=now_pulse1;
now_pulse1<=key_pulse;
pre_pulse2<=now_pulse2;
now_pulse2<=key2_pulse;
pre_pulse3<=now_pulse3;
now_pulse3<=key3_pulse;
if(~pre_pulse1&now_pulse1)
begin
stop<=~stop;
end
else if(~pre_pulse2&now_pulse2)
begin
stop<=1'b1;
state<=0;
end
else if(~pre_pulse3&now_pulse3)
begin
stop<=1'b1;
state<=0;
end
else
begin
stop=stop;
end In this project, we started from making the development board sound. We carried out in-depth exploration of various functional modules, especially the realization of the storage function in Verilog statements, so as to realize the storage of user information, music library, free playing and other contents. We think the register function is the crucial part in Verilog.
In addition, we tried different tones and rhythms for the specific goal of "small piano". We tried some challging functions like VGA, adjusting the position of keys, recording user-played music and so on. During the exploration, we get more new knowledge about using Verilog.
Last but not least, we have implemented concise calls at the top level, and achieved a good structured modeling of the entire project. At the same time, thanks to our close cooperation on team cooperation, we avoid the situation that the separation of each other leads to difficulties in the top-level connection.
However, because of the time limit, this project still has many things can be explored. For example, the storage of RAM when using VGA, how to update the music library in recording function and so on. We also really realize the importance of file classification and version control through painful lessons in the project.
Although we meet some difficulties in exploring new functions and using Vivado, we still appreciate this nice travel in Digital Logical Project. We implemented nearly all the functions advised in request, and came up with some ideas to face the user. We think we truly make a progress in this project. Thanks for both of us. Thanks for all.
