Hi I am not in home now, I will return on next week. Dmitry

[board707]

Hi, I just returned, we could continue.

Please, what other chips are there on the panel besides the driver?

[digi55]

Hi @board707 , I'm on vacation right now. I'll be back next week. Since the panel is outdoor, the integrated circuits are covered with varnish, it is very difficult to read. I will try to find a solution. Thank you very much for your help.

Ok, will continue later

[digi55]

Hi , @board707 I just returned. I found some information about this panel. LED chips : Sm16169 I hope it helps. I will try to read it with a microscope too.

[board707]

LED chips : Sm16169

Are you sure? Unfortunately, this driver is known as a new SM-PWM type, and I don't have a datasheet for it. It is not supported by the library yet.

[digi55]

Hi, @board707 it's very hard to read because it's varnished. as far as I can read CHIPONE ICN2037, ICND2010A chips are available. I ordered a microscope. I hope to be able to give more precise information when it arrives.

[board707]

Thanks This is encouraging since ICDN2037 is a supported driver. Do you have any info about the scan? is this panel a 80x40 scan10 or scan5 matrix?

Could you change the definition of the DMD class to options below: Variant A

#define RGB80x40s10_pt1 4,80,40,10,1
DMD_RGB <RGB80x40s10_pt1, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

Variant B

#define RGB80x40s10SR_pt1 3,80,40,10,1
DMD_RGB_SHIFTREG_ABC <RGB80x40s10SR_pt1, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

and run the test for each? Also please increase delay between drawing pixels to 30ms

[digi55]

Variant A https://github.com/user-attachments/assets/112d39e4-0521-43f6-9ed6-f86218027611

[digi55]

Variant B https://github.com/user-attachments/assets/10d3b990-6e20-495d-ab35-c1fa2001f4bf

[board707]

Please confirm - variant B fills the entire panel evenly if you continue?

[digi55]

I will test it tomorrow and let you know.

[digi55]

Please confirm - variant B fills the entire panel evenly if you continue?

Yes

[board707]

Thank you, I'll work with it

[digi55]

Thank you too

[board707]

Please add this code after #include "DMD_RGB.h" line:

template <int MUX_CNT, int P_Width, int P_Height, int SCAN, int Pixbase, int Pattern, int COL_DEPTH>
class DMD_RGB<MUX_CNT, P_Width, P_Height, SCAN, 122, Pixbase, Pattern, COL_DEPTH> : public DMD_RGB_BASE2<COL_DEPTH>
{
public:
  DMD_RGB(uint8_t* mux_list, byte _pin_nOE, byte _pin_SCLK, uint8_t* pinlist,
    byte panelsWide, byte panelsHigh, bool d_buf = false) :
    DMD_RGB_BASE2<COL_DEPTH>(MUX_CNT, mux_list, _pin_nOE, _pin_SCLK, pinlist,
      panelsWide, panelsHigh, d_buf, COL_DEPTH, SCAN, P_Width, P_Height)
  {
        this->fast_Hbyte = false;
        this->use_shift = false;
        }
    // Fast text shift is disabled for complex patterns, so we don't need the method
        void disableFastTextShift(bool shift) override {}

protected:

  uint16_t get_base_addr(int16_t& x, int16_t& y) override {
    this->transform_XY(x, y);
    uint8_t pol_y = y % this->pol_displ;
    x += (y / this->DMD_PIXELS_DOWN) * this->WIDTH;
    uint16_t base_addr = (pol_y % this->nRows) * this->x_len +
            (x / Pixbase) * this->multiplex * Pixbase + x % Pixbase;
    if (((x % P_Width)/Pixbase)%2) { if (pol_y >=  this->nRows)  base_addr += Pixbase; }          // LPS
    else { if (pol_y < this->nRows)  base_addr += Pixbase; }    // UPS

    return base_addr;
  }

};

and use it in definition of the class:

#define RGB80x40s10SR_digi55 3,80,40,10,122,16,1
DMD_RGB_SHIFTREG_ABC <RGB80x40s10SR_digi55,  COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

I did what you said, I get an error like this

[board707]

Compilation error: wrong number of template arguments (8, should be 6)

This error means that you use a version of the library prior to 1.1.3 Please install the latest version.

[digi55]

Now everything works correctly. Thank you so much @board707

[board707]

You are welcome :)

[digi55]

The scrolling text is not smooth as the P4 panel, which I used before. I will do some more testing tomorrow. Do you have any advice on why this is happening?

[board707]

Is this the same as isuue #86 ?

[digi55]

Thank you for your advice. I will try it tomorrow and let you know.

[board707]

Hi I just added a new pattern RGB80x40s10SR_digi55 for your matrix from this topic to the new library release. Now you can use it without adding a pattern code to your sketch.

[digi55]

Thank you so much @board707
