Midi foot controller with Banks (code)

intergalatico · Feb 1, 2016

Hello,

I am building a midi foot controller with 12x buttons (2x for Bank UP/Down), 10x TFT Color Graphic Displays, 1x 2 Digits Display (to display with Bank I am).

The TFT's should display the function of the foot switch.

It will be like this:

6 7 8 9 10
1 2 3 4 5

Where the 1-5 Buttons are to send PC (Program Change) and the 6-10 CC messages. So that when we are on the Program 1 (Button 1), the display 1 will give me the name of the program and the displays form 6 – 10 will display the functions according to this program. On the Program 2 the 6 – 10 will have other functions and so other display configuration. And so on through programs 3 to 5.

With the Bank buttons I will be able to have more then only 5 programs.

I would be very thankful if someone could give me a code example where I can begin. I did find some examples around forums but none with the Bank function that I want.

The whole Graphic library and display things I am taking care. I am using Teensy 3.2

Thank you very much!

Cheers

I thought bank select was CC 0 MSB and CC 32 LSB ...

Without knowing more ... I would suggest that you would use CC 0 and CC 32 to set the bank, and then send the relevant program change straight after. Bank select doesn't take effect until a PC is received...BUT it all depends on the midi implementation you are trying to 'drive' ...

I use CC 0 and CC 32 (i.e. I have code for setting them) but I use them to send continuous 10 bit volume data !! and I don't use Program Change.

Thank you Adrian,

but I think I didn't explained myself too clear. I want to change the banks INSIDE my controller in a way that I will have more functions on the same Button.

I was trying to use the "bounce" example from the "bounce" library, and I add a second button to go up and down. My idea was that the "counter" will be my Bank number. So for each "counter" number I will have a "if" function where I can put all the functions from the all 10 foot switches.

The problem right now is that I want to have 10 Banks. I don't know how to reset the counter after reaching the 10th bank. I am sure is a easy tweaking but I can't find in anyplace. Someone?

Thank you!

Here my code:

Code:

#include <Bounce.h>

const int buttonPinDown = 5;
const int buttonPinUP = 8;
Bounce pushbuttonDown = Bounce(buttonPinDown, 10);  // 10 ms debounce
Bounce pushbuttonUp = Bounce(buttonPinUP, 10);  // 10 ms debounce

void setup() {
  pinMode(buttonPinDown, INPUT_PULLUP);
  pinMode(buttonPinUP, INPUT_PULLUP);
  Serial.begin(57600);
  Serial.println("Pushbutton Bounce library test:");
}

byte previousState = HIGH;         // what state was the button last time
unsigned int count = 0;            // how many times has it changed to low
unsigned long countAt = 0;         // when count changed
unsigned int countPrinted = 0;     // last count printed

void loop() {
  
  if (pushbuttonDown.update()) {
    if (pushbuttonDown.fallingEdge()) {
      count = count + 1;
      countAt = millis();
    }
  } else {
    if (count != countPrinted) {
      unsigned long nowMillis = millis();
      if (nowMillis - countAt > 100) {
        Serial.print("count: ");
        Serial.println(count);
        countPrinted = count;
      }
    }
  }

 if (pushbuttonUp.update()) {
    if (pushbuttonUp.fallingEdge()) {
      count = count - 1;
      countAt = millis();
    }
  } else {
    if (count != countPrinted) {
      unsigned long nowMillis = millis();
      if (nowMillis - countAt > 100) {
        Serial.print("count: ");
        Serial.println(count);
        countPrinted = count;
      }
    }
  }
 
}

Ah sorry I get you now ... I actually do something similar for controller modes (I have one set of buttons and 3 different choosable 'mappings' as to what they do) .

So .... create a function to poll two buttons and do your count ... I would suggest that you put in some thing like this at the end...

Code:

if (count > 10) {count = 10;}
if (count < 1) {count = 1;}

or reset it to whatever.

Then I would have a function that reads in all of the buttons data, and then process it using the switch / case syntax...

Code:

//read in the buttons data, then process it ..

switch (count)
{
case 1:
//code using buttons data...
break;

case 2:
//code
break;

case 3:
//code
break;

}

I've found that good quality switches do not need 10ms debouncing 2 ms should be enough. I use 1.2ms (1.5 is the 'average', I read somewhere)

Anyway, try this, maybe? I haven't compiled it.

Code:

#include <Bounce.h>

const int buttonPinDown = 5;
const int buttonPinUP = 8;
Bounce pushbuttonDown = Bounce(buttonPinDown, 5);  // 5 ms debounce
Bounce pushbuttonUp = Bounce(buttonPinUP, 5);  // 5 ms debounce
bool buttonUp = false;
bool buttonDown= false;
void bankSelect();
void buttonProcess();

void setup() {
  pinMode(buttonPinDown, INPUT_PULLUP);
  pinMode(buttonPinUP, INPUT_PULLUP);
  Serial.begin(57600);
  Serial.println("Pushbutton Bounce library test:");
}


unsigned int count = 1;            // bank number


void loop() {
bankSelect();
buttonProcess();
delay(1);
}

void bankSelect(){
 if (pushbuttonDown.update()) {  
    if (pushbuttonDown.fallingEdge()) {count ++; buttonDown = true; if (count > 10) {count = 1;}
   }
if (buttonDown) {Serial.println(String ("bank: ") + count); buttonDown=false;}
 
if (pushbuttonUp.update()) {  
   if (pushbuttonUp.fallingEdge()) { count--; buttonUp=true; if (count < 1) {count = 10;}
    }
  if (buttonUp) {Serial.println(String ("bank: ") + count); buttonUp=false;}  
}

void buttonProcess(){
//read in the buttons data, then process it ..

switch (count)
{
case 1:
true;//code using buttons data...
break;
case 2:
true;//code
break;
case 3:
true;//code
break;
}
}

Hey Adrian,

thank you so much that you toke your time to write this for me! I really appreciate!

But, 2 things:
1. The counter on the ascending direction is skipping the number "1" and on the descending direction the number "9".
2. Is possible to make that the counter after the "10" don't still on the "10" but reset to "0"? Like a circle.

Here is what happens on the serial monitor when I start to pull the "pushbuttonUp" 11 times and then "pushbuttonDown" also 11 times:

Code:

bank: 2
bank: 3
bank: 4
bank: 5
bank: 6
bank: 7
bank: 8
bank: 9
bank: 10
bank: 10
bank: 10
bank: 8
bank: 7
bank: 6
bank: 5
bank: 4
bank: 3
bank: 2
bank: 1
bank: 0
bank: 0

Again, thank you!!!

adrian · Feb 10, 2016

I've edited the code (ABOVE) slightly (changed the debounce time, and a bit of a restructure, made it 'circular' ...) Should work!! I will test it at home later ... sorry it didn't work first time ... I suspect it might be a timing issue, so I have added in a slight delay.

intergalatico · Feb 10, 2016

Thank you! But you didn't posted the code... did you forgot or you want to try at home first?

But thank you anyway, really!

EDIT: Oh, I got it! Sorry! You changed on the code above! Thank you!

I am trying, and now I have a cycle movement but the Bank Up button goes just one step forward then wont work anymore. At first wont compile but I put some "}" that was missing one the "void bankSelect()":

Code:

#include <Bounce.h>

const int buttonPinDown = 13;
const int buttonPinUP = 14;
Bounce pushbuttonDown = Bounce(buttonPinDown, 5);  // 5 ms debounce
Bounce pushbuttonUp = Bounce(buttonPinUP, 5);  // 5 ms debounce
bool buttonUp = false;
bool buttonDown= false;
void bankSelect();
void buttonProcess();

void setup() {
  pinMode(buttonPinDown, INPUT_PULLUP);
  pinMode(buttonPinUP, INPUT_PULLUP);
  Serial.begin(57600);
  Serial.println("Pushbutton Bounce library test:");
}


unsigned int count = 1;            // bank number


void loop() {
bankSelect();
buttonProcess();
delay(1);
}

void bankSelect(){
 if (pushbuttonDown.update()) {  
 if (pushbuttonDown.fallingEdge()) {count ++; buttonDown=true; if (count > 10) {count = 1;} }
   }
 if (buttonDown) {Serial.println(String ("bank: ") + count); buttonDown=false;}
 
 if (pushbuttonUp.update()) {  
 if (pushbuttonUp.fallingEdge()) { count--; buttonUp=true; if (count < 1) {count = 10;} }
    }
 if (buttonUp) {Serial.println(String ("bank: ") + count); buttonUp=false;}  
}

void buttonProcess(){
//read in the buttons data, then process it ..

switch (count)
{
case 1:
true;//code using buttons data...
break;
case 2:
true;//code
break;
case 3:
true;//code
break;
}
}

EDIT: Sorry!!! I changed the pins, from 13, 14 to 15, 16 and now is working just like supposed to do! Thanks a lot! I will develop further with the other functions and will post here! Thanks for your help!!!

adrian · Feb 10, 2016

Cool ...I just noticed the missing brackets!! I don't have a compiler on me, so sorry about that .... good luck!

intergalatico · Feb 12, 2016

So, I am trying to get further and noticed that the program is more complex that I though! To print one thing on the display that is selected means that the other ones have to be cleaned and so goes on. It would be more easy to have the multiple functions grouped in one. I know that that is possible but I don't know how to do it.

Something like this: When I print a name on the screen I have to do this:

Code:

  tft1.setCursor(30, 70);
  tft1.setRotation(45);
  tft1.fillScreen(patch01Background);
  tft1.setTextColor(BLACK);
  tft1.setTextSize(4);
  tft1.println(patch01);

Would be way easier if I just had to type: writePatch01() (or something like this).

How I can do this?

Thank you!

Nevermind. I figured out how to make a group of functions.

Now I move to the problem that the program is printing on the display the whole time that the loop is running. How can I make to print just once?

Thank you!

sandalhat · Feb 12, 2016

First post here and on my phone so I won't be able to write example code. I think you're asking how to only write to an LCD when something changes? If so, you could have an if statement before writing anything to an LCD that checks a flag that gets set when you push a button (and subsequently cleared when writing to an lcd). So button 1 could maybe set a Boolean value to true and the code that writes to lcd 1 will only do so if the Boolean is true (and will then set it to false so it won't repeatedly write after pressing the button once).

adrian · Feb 12, 2016

I think sandalhat is suggesting:

Code:

bool change1 = false; //initialise

//set change1 with some code ....yadayada, and then call the 'write' function:

FUNCTION(change1);


void FUNCTION (bool &change) //pass the flag by reference
{
if (change) {/*lcdwrite()*;/ change = false;} // write lcd and reset flag
}

and you just keep on supplying the change1 as true 1 or false 0, calling the FUNCTION repeatedly

Thank you guys! But I am facing difficulties to put this on my code. I understood the concept but I can't put it to work. Could somebody have the kindness to adapt this to my code?

Here is what I tried:

Code:

// before SETUP
bool preset01Active= false;
bool preset02Active= false;
bool stomp01Active= false;
bool stomp02Active= false;

// then on the loop

switch (count)
{
case 1: true;

//Display #1
  if (preset01Active= false){
      printPreset01();
      printPreset02();
      printStomp01();
      printStomp02();
      preset01Active= true;
      preset02Active= false;
  }
