Sdcard configuration place

Sineg

I have a megatronics V3 with a RepRap Discount Smart LCD, I'm runing a repetier Firmware and the lcd's works and the encoder too, but
the sdcard reader sems not to work. In the sdcard menu, I haven't the options to manualy detect the sd and if I restart the printer I doesn't detect to.
If I upload a MArlin firmware the SDcard works fine. So the external sdcard works.
I think is a littel mistake with my firware but i can't find it.

Feature_Controller is set to 2

Any suggestion to find the place on firmware to solve it?

Please use dev version. Then in DisplayList.h you find

#elif MOTHERBOARD == 703 // Megatronics v3.0

#define UI_DISPLAY_RS_PIN 32

#define UI_DISPLAY_RW_PIN -1

#define UI_DISPLAY_ENABLE_PIN 31

#define UI_DISPLAY_D0_PIN -1

#define UI_DISPLAY_D1_PIN -1

#define UI_DISPLAY_D2_PIN -1

#define UI_DISPLAY_D3_PIN -1

#define UI_DISPLAY_D4_PIN 14

#define UI_DISPLAY_D5_PIN 30

#define UI_DISPLAY_D6_PIN 39

#define UI_ENCODER_A 45

#define UI_ENCODER_B 44

#define UI_ENCODER_CLICK 33

#define UI_INVERT_MENU_DIRECTION 1

#define UI_RESET_PIN -1

for that display and as you see it is missing the sd card section. I think it is because the board has a sd card, right? Don't have that board so can not say much to it. There you would set normally the sd card pins like in some other board definitions you see for same display. If you have a tested solution, please let us know so we can merge that into official solution.

Yes the board have sd card on it.
I'll try to define the UI code for the sd and I'll tell you how it goes.

the pins are set correctly, Miso Mosi, SCK and SDSS are well defined.

May I have to insert this:

#undef SDCARDDETECT
#define SDCARDDETECT -1
#undef SDCARDDETECTINVERTED
#define SDCARDDETECTINVERTED 0
#ifndef UI_VOLTAGE_LEVEL
#define UI_VOLTAGE_LEVEL 1 // Set 1=5 o 0=3.3 V

Because, if I compare with other boards, all have the same definition, the only difference the asignation pins.
So... What is the SD Card section that I need?

Repetier

#define SCK_PIN 52

#define MISO_PIN 50

#define MOSI_PIN 51

are the same for AVR boards as these are the only available hardware SPI pins.

What will differ is SDSS and SDCARDDETECT and SDCARDDETECTINVERTED. Setting these to right pins should already help in your case. If youi don't define it the board sd card should be the active one.
