ESP32-HUB75-MatrixPanel-DMA panel 32x32 1/16 scan , MBI5124 and ICND2018

Hi @mrcodetastic , I have a 32x32 LED matrix with 1/16 scan, using MBI5124 to control the columns and ICND2018 to control the rows. I'm trying to display a simple 'hello' message, but it's not working.

Jul 01 '25 06:07 tolik2025

The problem seems to be with how I'm controlling the ICND2018. Can you help me?

The problem with the ICND2018 chip is easy to solve. It is a shift-register type row multiplexer. To work with it you need to add an option to your mxconfig:

mxconfig.driver = HUB75_I2S_CFG::DP3246_SM5368;

But I don't know if the MBI5124 driver is compatible with the library code. So, first, try adding the option for ICND2018 and see the result

Here is my code and The LED panel is black : /**********************************************************************

The library by default supports simple 'shift register' based panels
with A,B,C,D,E lines to select a specific row, but there are plenty
of examples of new chips coming on the market that work different.
Please search through the project's issues. For some of these chips
(you will need to look at the back of your panel to identify), this
library has workarounds. This can be configured through using one of:

what if we try the option

mxconfig.driver = HUB75_I2S_CFG::MBI5124;

instead of HUB75_I2S_CFG::DP3246_SM5368;

will anything appear on the panel?

Hi @board707 with the option mxconfig.driver = HUB75_I2S_CFG::MBI5124;

When I tried to display just one pixel on the LED panel using simple code, I got four pairs of pixels lighting up instead.

I am using this code:

#include <ESP32-HUB75-MatrixPanel-I2S-DMA.h>

#define PANEL_RES_X 32 #define PANEL_RES_Y 32 #define PANEL_CHAIN_LEN 1

HUB75_I2S_CFG::i2s_pins _pins = { .r1 = 4, .g1 = 5, .b1 = 6, .r2 = 7, .g2 = 15, .b2 = 16, .a = 18, .b = 8, .c = 3, .d = -1, .e = -1, .lat = 40, .oe = 2, .clk = 41 };

HUB75_I2S_CFG mxconfig(PANEL_RES_X, PANEL_RES_Y, PANEL_CHAIN_LEN, _pins); MatrixPanel_I2S_DMA matrix(mxconfig);

void setup() { matrix.begin(); matrix.setBrightness8(64);
matrix.drawPixel(1, 1, matrix.color565(255, 0, 0)); } void loop() { }

Only with the DP3246_SM5368 configuration does the panel go dark; the other configurations give the same result.

Jul 02 '25 02:07 tolik2025

I found in the ICND2018 datasheet that they use the pins SDIN, DCK, and RCK instead of A, B, C.

I think you misunderstood the datasheet. It does not say that some pins are used instead of others, it means that the ICND2018 pins SDIN, DCK, and RCK are correspond to C, A and B pins on panel HUB75 connector. This is standard pinout for shift_register type line switchers, that is, no pins need to be swapped.

Jul 02 '25 09:07 board707

actually ICND2018 is different from normal shift registers.

Actually your selectRow() routine code above has no difference with standard code for shift_register type multiplexers.

I can't convert to use DMA + I2S, can you help me?

how can I help? Using a HUB75 panels via DMA + I2S - is exactly what the library written for. But it doesn't suit you

Please show the Arduino compile output of your test code.

with the DP3246_SM5368 configuration does the panel go dark; the other configurations give the same result.

Please show the Arduino compile output of your test code.

The Arduino compile output doesn't show anything and there are no errors. Look at the image below and you'll understand why my LED panel can't work with this library.

Aug 02 '25 03:08 tolik2025

I don't see anything on the picture that prevents the library to work with the panel. The actual library code has the support for both decoder types presented on your picture.

Could you show a last part of the compile output (last 15-20 lines) ?

I don't see any sign of using a ESP32-HUB75-MatrixPanel-DMA library in your code:

4_OtherShiftDriverPanel.zip this is code , I am using.

Aug 02 '25 05:08 tolik2025

You are using the library incorrectly. Why did you copy its files to the sketch directory? Install the library using Arduino IDE, for example, the same way you installed FastLED.

You don't put FastLED in the same folder, right? Why did you do so for ESP32-HUB75-MatrixPanel-DMA library?

After installing the library properly - start from simple code. Remove all parts not related with HUB75 panels, for example a FastLED code. Start from the library examples.

Aug 02 '25 05:08 board707

@tolik2025 I'm not saying that this will make everything work right away. However, there's no point in looking for errors in the library if you installed it incorrectly.

Aug 02 '25 05:08 board707

I deleted all the files in the code folder. The LED panel is still completely dark.

You use an outdated version of the library;

Using library ESP32 HUB75 LED MATRIX PANEL DMA Display at version 3.0.11

The latest version with the support of shift_register type multiplexers is 3.0.12

Aug 02 '25 06:08 board707

I do not see version 3.0.12 in github and in Arduino IDE

Aug 02 '25 06:08 tolik2025

V 3.0.12 do not released yet. Install it directly from GitHub via green button on the upper right of the library page.

@board707 I have sent the email.

Aug 02 '25 09:08 tolik2025

Thanks with the help of Mr. @board707 , the LED panel now displays 4 sections with the colors Red, Green, Blue, and Yellow. I am using the example "OtherShiftDriverPanel".
