hi everyone i have managed to get this TFT (http://blog.simtronyx.de/wp-content/uploads/Anschlussbelegung-1.8-Zoll-TFT-Farb-Display-HY-1.8-SPI-1024x768.jpg) to work (no logic converter needs to be inserted). So after good results i ordered another TFT but get this one: http://devacron.com/wp-content/uploads/2014/05/arduino_tft_128x160b1.jpg
So both of them are with an ST7735 Chipset because i get on both a picture. The second one with header pins only for the display i need to connect a logic converter to get a nice picture.
But how to use the SD Card? I have soldered the 16Pin Header on the other side as the yellow pin headers (and only wired here the Arduino) but i got no information from the SD Card. Did someone manage to get it working? Did you need for the SD Card also the logic level converter (the MOSI /SDA and CLK / SCLK are shared).
So no conclusion how to get this to work.
after searching i found this: https://www.youtube.com/watch?v=-dk_xDSTqEY -> here i can see there is nothing soldered on the tft pcb but in the explanation there is this http://i.imgur.com/vEKAYi4.jpg and this http://i.imgur.com/nLnwFC0.jpg
now i have tried this: http://i.imgur.com/nLnwFC0.jpg but it also didn't work. Does nobody use this TFT? They sell it on Banggood like hell but only a few people did get it to work. If there is somebody who has done this pls be so helpful and explain how.
