      Hello @Kazik

      the LCD backlight is probably missing. It's controlled via GPIO27 driving VLED. See schematic. Also in the GFX library GPIO27 is setup as PWM backlight. See here.

      Thanks

      Thank You very much it helped. But now i must be connected over usb to show something on screen. Without usb screen blinks for sec and black. And navigation over menu is very poor

        Hello @Kazik

        please read the yellow note from the documentation.

        After triggering the wake up signal, the hold(G4) pin needs to be set to a high level (1) in program initialization to maintain the power supply, otherwise the device will enter the shutdown state again.

        Thanks

          I dont know where to put this in marauder code. I need advice. I managed to compile the code to work on plus 2. only works if the usb cable is connected. Marauder code is very problematic for M5Stickc.

            you'd put that at the beginning of setup().

              @felmue just simple like this?
              // Set digital pin 4 (GPIO4) to high state
              pinMode(4, OUTPUT);
              digitalWrite(4, HIGH);

                    @felmue hellol could you tell me is pins to connect sd card module to plus2 are the same as plus?
                    3V3 > 3V3
                    CS > GND
                    MOSI > G26
                    CLK > G0
                    MISO > G36
                    GND > GND.
                    Of course I must change pins in source code.

                      Hello @Kazik

                      from what I can tell looking at the documentation for the two M5Sticks here and here I would say the same GPIOs can be used for both.

                      Please note: I do not have an M5StickCPlus2 so I cannot test this myself.

                      Thanks

                        @felmue So I source code I must change CS pin to LOW? To match for GND?

                          SPI bus can handle multiple (slave) devices. Each has its own CS. See here.

                          That said, if the SD card it the only slave device it's ok to connect its CS directly to GND. If you want to use a GPIO for CS then yes, set it to LOW.

                          Thanks
