HT1621 induvidual segment control

[kluuko]

I cant find the files. i tried it on my Micro SD (Ima call SD from now) AND on my device itself (SSD from now) and it cant find a crumb

@sterretje

Copy the two library files HT1621.h and HT1621.cpp from the library's src directory. On my Windows system it's C:\Users\bugge\OneDrive\Documents\Arduino\libraries\HT1621\src

[sterretje]

Open File → Preferences.

In the sketchbook directory should be a directory called libraries. In there should be a directory for HT1621 library with a src subdirectory where you should find the two files

If your username on the PC is kluuko, replace bugge by kluuko.

i know, its just 3:45 AM and im not gona do that now. (I know i need to sleep)

[kluuko]

thanks i got the location.

[kluuko]

it gives error:

No connection established. Last error: Error: connect ECONNREFUSED ::1:58894

Compilation error: No connection established. Last error: Error: connect ECONNREFUSED ::1:58894

And something abt linux?

i copied the code above:

@sterretje

HT1621 lcd;
void setup()
{
  lcd.begin(LCD_CS_PIN, LCD_WR_PIN, LCD_DATA_PIN);
  lcd.backlight();
  lcd.clear();
  // sterretje: no battery level ??
  lcd.setBatteryLevel(0);
}

void loop()
{
  // create a buffer for the display
  byte buffer[6];

  // clear the buffer
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0x00;
  }

  // switch everything on.
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0xFF;
  }
  lcd.print(buffer);
}

@kluuko

Compilation error: No connection established. Last error: Error: connect ECONNREFUSED ::1:58894

I can't help you with that one; I think the IDE might try to connect to another process on your computer (which I think is normal) and can't for some reason.

@kluuko

And something abt linux?

What about Linux?

[kluuko]

I got send to a website wich said some sh*t abt conecting amth to linux (I have windows)

Hi @kluuko

@kluuko

it gives error:

No connection established. Last error: Error: connect ECONNREFUSED ::1:58894

Compilation error: No connection established. Last error: Error: connect ECONNREFUSED ::1:58894

I'm going to ask you to provide the full verbose output from a compilation.

This procedure is not intended to solve the problem. The purpose is to gather more information.

---

Please do this:

1. Open the sketch in Arduino IDE.
2. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
3. Check the box next to "Show verbose output during: ☐ compile" in the "Preferences" dialog.
4. Click the "OK" button.
   The "Preferences" dialog will close.
5. Select Sketch > Verify/Compile from the Arduino IDE menus.
6. Wait for the compilation to fail.
7. You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
8. Open a reply here on this forum topic by clicking the "Reply" button.
9. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
   
10. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the compilation output into the code block.
11. Move the cursor outside of the code block markup before you add any additional text to your reply.
12. Click the "Reply" button to publish the post.

In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here.

Click here for attachment instructions

1. Open any text editor program.
2. Paste the copied output into the text editor.
3. Save the file in .txt format.
4. Open a reply here on this forum topic by clicking the "Reply" button.
5. Click the "Upload" icon () on the post composer toolbar:
   
   
   
   The "Open" dialog will open.
6. Select the .txt file you saved from the "Open" dialog.
7. Click the "Open" button.
   The dialog will close.
8. Click the "Reply" button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.

[kluuko]

@ptillisch just dont ask why i spelled it wrong, its on purpose. and here is the thing you asked

[ptillisch]

OK, this error is easy enough to solve. Line 12 of your sketch code is:

   lcd.begin(13, 12, 8,);

Note that there is a , after the 8 argument in that lcd.begin function call. This trailing comma is not allowed by the C++ compiler. So remove it:

   lcd.begin(13, 12, 8);

After fixing that bug, compile or upload you sketch once more. Hopefully everything will work as expected this time.

[kluuko]

IT WORKS! (I did have to fight my microSD but it works). can someone put the solution in 1 mesage or am i gona do that (To mark it as solution)

[kluuko]

This is the solution:

@sterretje

Disclaimer: I do not have the display so I can't verify if the approach described below will work.

@kluuko

but it doesnt explain what i want, being able to control every single segment induvidualy.

The library does not support that; you'll have to hack it.

1. You can hack the library directly; disadvantage is that any update of the library will wipe out the changes that you made.
2. Use a copy of the library in your sketch directory; disadvantage is that you need to do this for every sketch that you write (although you can copy).
3. Other ways that might be more complicated.

This post demonstrates option 2. Note that the "library" is no longer a library but the files are part of the sketch.

• Create a new sketch; I called it 1443614_HT1621raw and save it.
• Copy the two library files HT1621.h and HT1621.cpp from the library's src directory. On my Windows system it's C:\Users\bugge\OneDrive\Documents\Arduino\libraries\HT1621\src.
• Locate the sketch on your computer; on my Windows system C:\Users\bugge\OneDrive\Documents\Arduino\1_forum.arduino.cc\1443614_HT1621raw.
• Paste the copied files.

Your IDE (in this case 2.3.8) will now have three tabs as show below.

You can see the main sketch file as well as the two files that were copied from the library.

Now you can modify those two files to support raw printing.
HT1621.h
Add the following line after the lines void print(const char* str, bool leftPadded = false); in the public section of the file

  // sterretje: support raw printing
  void print(byte *data);

HT1621.cpp
Add the following function after the HHT1621::print(const char* str, bool leftPadded) function and before the HT1621::setdecimalseparator(int decimaldigits) function

// sterretje: support raw printing
void HT1621::print(byte *data)
{
  for(int i = 0; i < 6; i++)
  {
    _buffer[i] = data[i];
  }
  update();
}

This print method copies the data that you pass to the display buffer and next updates the display.

You can now write a simple sketch that should switch all elements of the display on. Note how to include the local copy of the "library".

// sterretje: note the use of double quotes
#include "HT1621.h"
#define LCD_CS_PIN 6
#define LCD_WR_PIN 7
#define LCD_DATA_PIN 8
#define DELAY_SINK 1000


HT1621 lcd;
void setup()
{
  lcd.begin(LCD_CS_PIN, LCD_WR_PIN, LCD_DATA_PIN);
  lcd.backlight();
  lcd.clear();
  // sterretje: no battery level ??
  lcd.setBatteryLevel(0);
}

void loop()
{
  // create a buffer for the display
  byte buffer[6];

  // clear the buffer
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0x00;
  }

  // switch everything on.
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0xFF;
  }
  lcd.print(buffer);
}

You can find the needed values in the README.md on your computer or at GitHub - valerionew/ht1621-7-seg: arduino library for 7-segment lcd based on ht1621 drivers · GitHub; it contains a text representation at the end of the values for the segments. Below in a slightly different format using hex values

  _0x10_
 |      |
0x01   0x20
 |_0x02_|
 |      |
0x04   0x40
 |_0x08_|

The decimal dot wil be 0x80.

You can combine them; e.g. 0x03 will give

|
 -

And 0x11 will give

 -

and here is to find the stuff:

@sterretje

Open File → Preferences.

In the sketchbook directory should be a directory called libraries. In there should be a directory for HT1621 library with a src subdirectory where you should find the two files

If your username on the PC is kluuko, replace bugge by kluuko.

Thanks @sterretje and @ptillisch for the solution thanks

[ptillisch]

You are welcome. I'm glad it is working now.

Regards, Per

[kluuko]

it works but it doesnt work, what i asked here works but now my main code where the hasle was for just stoped working as intended.

void loop() {
  lcd.print(((millis() - 750)/1000) / 60, 1); // <--- here (the 1 decimal is always 0)
  lcd.setBatteryLevel((((millis() - 750) % 1500) /500) + 1);
  digitalWrite(3, HIGH);
  digitalWrite(3, LOW);
  delay(500);
}

so i need some help still.

[sterretje]

You should post the full code or a representative example that shows the problem.

The code in post #6 (and #59) disabled the battery indicator, maybe that is the problem?

[kluuko]

#include "HT1621.h"
#define LCD_CS_PIN 6
#define LCD_WR_PIN 7
#define LCD_DATA_PIN 8
#define DELAY_SINK 1000


HT1621 lcd;
void setup()
{
  lcd.begin(13, 12, 8);
  lcd.backlight();

  // sterretje: no battery level ??
  lcd.setBatteryLevel(0);
    // create a buffer for the display
  byte buffer[6];

  // clear the buffer
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0x00;
  }

  // switch everything on.
  for (byte cnt = 0; cnt < 6; cnt++)
  {
    buffer[cnt] = 0xFF;
  }
  lcd.print(buffer);
  delay(750);
  lcd.clear();
}

void loop() {
  lcd.print(((millis() - 750)/1000) / 60, 1);
  lcd.setBatteryLevel((((millis() - 750) % 1500) /500) + 1);
  digitalWrite(3, HIGH);
  digitalWrite(3, LOW);
  delay(500);
}

here it is

[sterretje]

OK, I was mistaken about the disabling of the battery level; the code in post #6 only sets it to level 0.

@kluuko

  digitalWrite(3, HIGH);
  digitalWrite(3, LOW);

What is that supposed to do?

@kluuko

// <--- here (the 1 decimal is always 0)

Is this your comment? And your problem? If so, the print method that you're using is for variable of type double. However your calculation uses integers and the result will be an integer.

What happens if you change lcd.print(((millis() - 750)/1000) / 60, 1); to lcd.print(((millis() - 750)/1000) / 60.0, 1);?

[kluuko]

It works. am i that stupid?
