hi folks
i have bought this TFT: http://www.ebay.de/itm/262259186625?_trksid=p2057872.m2749.l2648&ssPageName=STRK%3AMEBIDX%3AIT
The panel works with the driver for the ST7735 library very well.
But i have also soldered 4 pins for the communication with the SD-Card on the side where no pins are soldered (the pins 11-14 which are marked as SDCard).The pins are CLK, MISO, MOSI, CS. I take a 1GB SD-Card and the source code from this side : An image slideshow with an Arduino and a tft display with a sd card module | simtronyx – Das Elektronik Blog
As mentioned i connect (SD)MOSI with (Yellow 4)DIN to (Arduino Uno)Pin 11
and (SD)CLK with (Yellow 5)CLK to (Arduino Uno)Pin 13. The (SD)CS i put on (Arduino Uno)Pin 4.
I have to say that the Data wires from the Arduino 8,9,10,11,13 are with a 1K resistor (so the SD Card also have a 1K resistor Datawire).
After the program starts the TFT went black and on the serial monitor i saw the "Initializing SD Card..." and after a few moments the "failed!" afterwards.
So if someone has got this SD Card to work which i have done wrong. I tested the (SD)CS with the resistor and withount - no change.
I test this now for a while and didn't find the solution and would be very happy if someone can help me out.
thx in advance
