    Hi,
    thank you for your help, but using software SPI does not fix it.
    I've try also non SPI Port as software SPI no luck.
    What bothers written in C it works fine.

    P.S: Sorry for double-posting I found the right forum after making the first post.

    Hi,
    I try to wire my LED Matrix(MAX7219) up to a ESP32 DEVKIT V1. To my knowledge, this code should turn all LEDs on:

    SPI2.setup({mosi:D23, sck:D18});
        let g = require('MAX7219').connect(SPI2,D5,4);
        g.displayTest(true);
    

    but nothing happens. At the start all LEDs flicker and than turn off or stay lit in random patterns.
    I double checked the wiring . I'm trying to connect via VSPI Ports on the board.
