Multiline scrolling possible

[maxmurugan]

hi sir

Currently Now multiline Fixed text and one scrolling text working fine

how to add multiline Scrolling text?

[board707]

It could be done the same way as "fixed text and one scrolling text'. Outputs the "fixed text" on a new position on each step - and you will get it as a scrolling.

[maxmurugan]

give some sample code please

[board707]

Please show your code for "fixed text and one scrolling text'.

[maxmurugan]

void loop(void)
{
dmd.selectFont(&UkrRusArial_F);
uint16_t bg = 0; // background - black
uint16_t interval = 32;
long prev_step = millis();
while (1)
{
/* if ((millis() - prev_step) > interval)
{
dmd.setTextColor(col[R1], bg); // --red color
if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
dmd.clearScreen(true);
Refresh =0;
dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 0 : 0, 0);
}
dmd.swapBuffers(true);
prev_step = millis();
}*/

if ((millis() - prev_step) > interval)
  {
    prev_step = millis();
    dmd.setTextColor(col[0], bg); // --red color
    if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
    dmd.clearScreen(true);
    dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 8 : 0, 0);
    }
    dmd.drawStringX(0, 0, "FIXED TEXT", col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
    dmd.swapBuffers(true);
 }

}
}

Thank you.
Could you try this?

if ((millis() - prev_step) > interval)
  {
    static uint8_t i =0;
    prev_step = millis();
    dmd.setTextColor(col[0], bg); // --red color
    if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
    dmd.clearScreen(true);
    dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 8 : 0, 0);
    }
   
      dmd.drawStringX(i, 0, "FIXED TEXT", col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
      i++;
      if (i >= dmd.width() ) i =0;
    
    dmd.swapBuffers(true);
 }

please check

[maxmurugan]

from left need full scrolling ,like bottom line

[maxmurugan]

change to left scrolling
please check

if ((millis() - prev_step) > interval)
{
static int8_t i = dmd.width();
prev_step = millis();
dmd.setTextColor(col[0], bg); // --red color
if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
dmd.clearScreen(true);
dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 8 : 0, 0);
}

  dmd.drawStringX(i, 0, "FIXED TEXT", col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
  i--;
  if (i <= -dmd.width() ) 
  {
    i = dmd.width();
  }

dmd.swapBuffers(true);

}

full scrolling from right

if ((millis() - prev_step) > interval)
  {
    static int16_t i =0;
    prev_step = millis();
    dmd.setTextColor(col[0], bg); // --red color
    if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
    dmd.clearScreen(true);
    dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 8 : 0, 0);
    }
   
      dmd.drawStringX(i, 0, "FIXED TEXT", col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
      i++;
      if (i >= dmd.width() ) i = -1 * (stringWidth("FIXED TEXT"));
    
    dmd.swapBuffers(true);
 }

wow nice working
thanks a lot

[maxmurugan]

Top line right side end of text not clear
how to clear?

[board707]

may be it helps:

if ((millis() - prev_step) > interval)
  {
    static int16_t i =0;
    prev_step = millis();
    dmd.setTextColor(col[0], bg); // --red color
    if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
    dmd.clearScreen(true);
    dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, (dmd.height() > 0) ? 8 : 0, 0);
    }
   
      dmd.drawStringX(i, 0, "FIXED TEXT", col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
      i++;
      if (i >= (dmd.width() +2) ) i = -1 * (stringWidth("FIXED TEXT"));
    
    dmd.swapBuffers(true);
 }

[maxmurugan]

same issue will happened

[board707]

ok, I will to see at the evening because it should be tested on hardware

[board707]

It is seems to work:

const char Fixed[] = "FIXED TEXT";
int16_t fixed_w = 0;
int16_t min_y, max_y;
dmd.stringBounds(Fixed, 0, &fixed_w, &min_y, &max_y);
while (1)
{

if ((millis() - prev_step) > interval)
  {
    static int16_t i =0;
    prev_step = millis();
    dmd.setTextColor(col[0], bg); // --red color
    if (dmd.stepMarquee(-1, 0) & 1) { // if text is reached screen bounds
    dmd.clearScreen(true);
    dmd.drawMarquee(Final_Message, strlen(Final_Message) , dmd.width() - 5, 16, 0);
    }
      dmd.drawFilledBox(i-2, min_y, i-1, max_y, bg);  // clear artefacts after moving the text
      dmd.drawStringX(i, 0, Fixed, col[1]); //- fixed messAGE USED FOR CLOCK OR DATE USING DS3231
      i++;
      if (i >= (dmd.width()+2) ) i = -1 * fixed_w;
    
    dmd.swapBuffers(true);
 }

}

[maxmurugan]

Now working fine

Thenk you
Can I use your videos as illustrations for a library manual?

[maxmurugan]

ok sir
thanks
