Insert SD card - SPI_HALF_SPEED [SOLVED]

[Romulo Gomes]

Hello Fernando,

The message asking me to insert SD card is appearing for me, and I have already researched several solutions, I have already tried several cards and in different formats, I have already checked all the welds on the board with a multimeter and they are all right, as well as trying the solutions presented in this one. link: https://ferduino.com/forum/viewtopic.php?f=8&t=104.

So I was not able to do the presented solution of changing the SPI_HALF_SPEED to SPI_FULL_SPEED or SPI_QUARTER_SPEED, I already tried to search with ctrl + F in the Ferduino code, but I did not find this command, I think this was taken from the code, am I right?

Hi Fernando,

I change for SPI_QUARTER_SPEED and SPI_FULL_SPEED, but without sucess.

I've been studying the code and am in doubt regarding the code below:

Code: Select all

//*****************************************************************************************
//************************** Dispositivos SPI *********************************************
//*****************************************************************************************
const byte SD_CARD = 0;
const byte ETHER_CARD = 1;
const byte RFM = 2;

#if defined USE_PIN_4_FOR_SD_CARD // Do not change this line
const byte ChipSelect_SD = 4; // Para cartão SD conectado no "ethernet shield".
#elif defined USE_PIN_53_FOR_SD_CARD // Do not change this line
const byte ChipSelect_SD = 53; // Para cartão SD conectado no TFT.
#else // Do not change this line
const byte ChipSelect_SD = 5; // Para o Ferduino Mega 2560
#endif // Do not change this line

#ifdef USE_PIN_53_FOR_SD_CARD // Do not change this line
const byte SelectSlave_ETH = 4;
#else // Do not change this line
const byte SelectSlave_ETH = 53;
#endif // Do not change this line

Do I have to change anything in this code?

One more question:

Do you have complete circuit for SHIELD TFT ITDB02 MEGA SHIELD V. 1.1?

Where your SD card is plugged? TFT or ethetnet shield?

[Romulo Gomes]

TFT, i don't have ethernet.

Uncomment this line:

Code: Select all

//#define USE_PIN_53_FOR_SD_CARD // Descomente esta linha se você tem o cartão SD conectado no TFT.

Hello Fernando, Unfortunately, it did not work either.

Do you have circuit of TFT shield?

I'll have to do a fine check of all the pins.

Hi!

I haven't schematic for this shield.

Please show me some pictures of your TFT shield.

Also try make the SD card work with test code.

Best regards.

Hi Fernando,

Below are the photos of my TFT shield.






I don't find test code for SD card...could I show me ?

Fernando,

I have refaced the welds of the board but continue the same message of INSERT THE SD CARD.
As for the test code of the SD card appeared a white screen and did not give any result.
Now I'm lost, what can I do? I do not know what else to do.

[Fernando Garcia]

Open the serial monitor to see the result and set the right baud rate according to code setup.

[Romulo Gomes]

I try all velocity, but nothing them done.
Seems like don't have comunication with SD card.

What can i do?

I think leave this project .

[Fernando Garcia]

Some options for you:

1 - Try learn a bit and fix your code and hardware;
2 - Buy another TFT shield kit and ask to a professional assembly it for you and set up the code correctly;
3 - Buy an ethernet shield with SD card slot and set up the code correctly.

Fernando, i have good news!
I change my TFT Shield from mega Shield v1.1 to mega Shield v2.2 and total sucess! Open start screen in First time.

I think my old TFT Shield have been problem.

Please close this Topic.
