AB panel chaining

[Josiko85]

@2dom Good morning, I'll give you my video and the code I use. Greetings

`#define PxMATRIX_COLOR_DEPTH 1
#define PxMATRIX_MAX_HEIGHT 16
#define PxMATRIX_MAX_WIDTH 64

#include <PxMatrix.h>
#include <avr/pgmspace.h>
// Pins for LED MATRIX
#define P_A 2
#define P_B 3
#define P_C 0
#define P_D 0
#define P_E 0
#define P_LAT 7
#define P_OE 8

PxMATRIX display(64, 16, P_LAT, P_OE, P_A, P_B);

// Some standard colors
uint16_t myCYAN = display.color565(0, 255, 255);
uint16_t myMAGENTA = display.color565(255, 0, 255);

unsigned long start_time=0;
uint8_t icon_index=0;

void setup() {
     Serial.begin(9600);
     display.begin(2);
     display.setMuxPattern(BINARY);
     display.setScanPattern(ZAGGIZ);
//     display.setBlockPattern(DBCA);
     display.setPanelsWidth(2);
//

display.clearDisplay();
for (int y=0; y<16; y++)
{
    for (int x=0; x<64; x++)
    {
      display.drawPixel(x, y, myCYAN);
      start_time = millis(); 
      while((millis()-start_time)<80)
          display.display(20);
    }
}

     display.clearDisplay();
    display.setTextColor(myCYAN);
     display.setCursor(2,0);
     display.print("1  2  3  4");
     display.setTextColor(myMAGENTA);
     display.setCursor(2,8);
     display.print("5  6  7  8");
     start_time = millis();
     while((millis()-start_time)<300000000)
         display.display(20);
}
void loop() { }`

enjoy the weekend

Can you please confirm that this code draws a straight diagonal white line on both panels when they are connected as single panel each? Please make sure this works on both, so both are actually the same.

#define PxMATRIX_COLOR_DEPTH 1
#include <PxMatrix.h>
#include <avr/pgmspace.h>
// Pins for LED MATRIX
#define P_A 2
#define P_B 3
#define P_LAT 7
#define P_OE 8

PxMATRIX display(32, 16, P_LAT, P_OE, P_A, P_B);

void setup() {
    display.begin(2);
    display.setMuxPattern(BINARY);
    display.setScanPattern(ZAGGIZ);
    display.clearDisplay();
    display.drawLine(0, 0, display.width()-1, display.height()-1, 0xFFFF);
}

void loop() {
    display.display(20);
}

Btw: To insert code, please paste your code, select it, then click "insert code" button.

Hi, my panels draw a white diagonal, but one of the panels has died because of a connection failure on my part.

In a couple of days I'll have another one and we can continue with the tests.

Oh, sorry to hear that :/

[Josiko85]

Oh, sorry to hear that

You can't do too many things at once. Talking to people and connecting things isn't usually a good idea.... But it could also be a power failure, my power is old and unstable.

[Josiko85]

I'm ready again to continue the tests and adjustments when you can.

[xsrf]

so, what do you now get with both connected together and this code?

#define PxMATRIX_COLOR_DEPTH 1
#include <PxMatrix.h>
#include <avr/pgmspace.h>
// Pins for LED MATRIX
#define P_A 2
#define P_B 3
#define P_LAT 7
#define P_OE 8

PxMATRIX display(64, 16, P_LAT, P_OE, P_A, P_B);

void setup() {
    display.begin(2);
    display.setMuxPattern(BINARY);
    display.setScanPattern(ZAGGIZ);
    display.setPanelsWidth(2);
    display.clearDisplay();
    display.drawLine(0, 0, display.width()-1, display.height()-1, 0xFFFF);
}

void loop() {
    display.display(20);
}

@xsrf In the video you can see the result but I did not intend to give work on the weekend. Thanks for the time dedicated https://youtu.be/RUy9zXyqA1o

[Josiko85]

@xsrf @2dom Please don't forget me, see when you can use several panels. I already have everything you need to prove. It would be great to be able to use them in chains to even rotate the letters.

[xsrf]

Please post a video of this with both panels chained. I have no clue what's going on there...

#define PxMATRIX_COLOR_DEPTH 1
#include <PxMatrix.h>
#include <avr/pgmspace.h>
// Pins for LED MATRIX
#define P_A 2
#define P_B 3
#define P_LAT 7
#define P_OE 8

PxMATRIX display(64, 16, P_LAT, P_OE, P_A, P_B);

void setup() {
    display.begin(2);
    display.setMuxPattern(BINARY);
    display.setScanPattern(ZAGGIZ);
    display.setPanelsWidth(2);
    display.clearDisplay();
    display.drawLine(0, 0, display.width()-1, display.height()-1, 0xFFFF);
}

void loop() {
    display.displayTestPixel(20);
}

Do you have an ESP8266 or ESP32 to compare with?

[Josiko85]

@xsrf Good afternoon, the problem is that are some new scand 1/2 panels, in another post I spoke with 2dom and he asked me to open a new problem, he changed things in the library to work with only one panel.

I'm using Arduino Mega 2560. The video is the same as the video from: [https://youtu.be/RUy9zXyqA1o]

[2dom]

The curious thing is that a single panel worked just fine with the settings before ? Can you try each panel you intend to chain together individually (as single panels) to make sure they are identical?

[Josiko85]

@2dom Good afternoon, I made some tests with separate panels and panels together, here I put 5 videos for you to see. I remain at your disposal.

panel type https://youtu.be/zrNwqhuzu7s panel A https://youtu.be/DDIGeoH8Ixs
panel B https://youtu.be/KuQkobdrV6E 2-panel https://youtu.be/4MowCbVrCBA scroll with 2 panel https://youtu.be/yR9c1uTkCrcl

[xsrf]

Okay, so both panels act as I would expect it - on their own and also when chained together. The problem is with the ZAGGIZ implementation for more than one panel.

If you need me to do any more tests, tell me and I'll send you the life or anything.

[2dom]

I will have a look as soon as I can ... Very busy ATM

[Josiko85]

You don't have to worry. When you can, thank you.

@2dom Hello, when you can remember me. If you can get three cascading panels to work, you've got another virtual beer guaranteed for the effort.

Thank you.
