No graphics [SOLVED]

Hello,

In the graphic screen on the ferduino there are no values of the temperature only 2 blue and 1 red line and the yellow time line .
I changed the line

Code: Select all

 
card.init(SPI_FULL_SPEED, ChipSelect_SD);


to

Code: Select all

 
card.init(SPI_HALF_SPEED, ChipSelect_SD);


because i use the card reader on the tft screen.
but still no data on the graphic.

You did this modification on TFT shield?

Yes i did that .Not the resistor to dim the tft.
i made the bridge and only the pins you suggested in the topic

You tried use the code for test available here?

What's the capacity of your SD card?

The SD card was formatted?

Hi,

i did not tried the test ( is it still possible when the complete code is in the ferduino),
Ethernt self works because i already connected it to joyreef and was able to control the led and time settings.
Its a 2 Gb micro sd card in a adapter to fit the slot on the tft. card was formated normal on W7 machine (fasted way)

Using a small code is more easy to find a problem.

Try it and tell me the result.

Ok .

I only have to upload the code thats under the SD card on the topic that you mentioned. No problem with all the other things already connected to the ferduino?
Il wil try later and post the result

Len

[Fernando Garcia]

No problem.

Hi,
code uploaded serieal monitor says

Can't open.

[Fernando Garcia]

Changed it:

Code: Select all

card.init(SPI_FULL_SPEED, ChipSelect_SD);

To:

Code: Select all

card.init(SPI_HALF_SPEED, ChipSelect_SD);

?

You can show me a picture of the modification that did on TFT shield?

Because the grapic didn't work i though it had something to do with the sd slot i found your topic and changed it after that no result.
the modification i did was exactly like you shown in your pictures a few pins and cut resitor R16 and connected to pin 4

I'm asking if you changed this line on code of test.

You can try with another SD card?

Sorry i misunderstood you, I didn't changed it on the testcode.
I will try some other sd cards and i change it on the test code and try again

Len

Sorry,

I think i forgot something i found this in this Thread

To prevent conflict between SD card from TFT and SD card on ethernet shield, you must remove pins 50, 51, 52 and 53 of the TFT shield.

Do i have to do this?

I did the mod i the topic u suggested topic and only welded the pins in the second photo (6 pins in a row and on the other side 20/21 an 2/3/4/5/6 and the complete double row on the side)

Is it still possible to use the SD slot on the ethernet module? if i remove the bridge between R16 and pin 4? Or is this now not possible anymore

Hi!

I'm messy now.

You have an ethernet shield or ethernet module?

The ethernet module shown on topic haven't a slot for SD card.

To prevent conflict between SD card from TFT and SD card on ethernet shield, you must remove pins 50, 51, 52 and 53 of the TFT shield.

This instruction is to ethernet shield.

Best regards.

Sorry,

Its the ethernet shield with the SD slot .I also made the board to connect the pins that are missing, like in the picture.But i failed to see that i had to remove pin 50/51/52/53.

So i think now i have to remove those pins on the ITDB02 mega shield ?

Hi!

You need make like this.

No need of bridge between R16 and pin 4.

Best regards.

Ok thanks.
I remove the bridge between R16 and pin 4 and remove the pins.After that i must use the SD slot on the ethernet shield.
