hello,
how do I have to wire this ILI9225 display
http://www.ebay.de/itm/201042408158?_trksid=p2059210.m2749.l2649&ssPageName=
to Arduino Mega pins if I wish to use SPI both for the TFT and for the SD slot?

standard TFT breakout pin
7. CLK surely is 52,
8. SDI is supposed to be MOSI (51),

but to which Arduino pins are connected standard
6. LED,
9. RS,
10. RST,
11. CS... ?


and to which are the following 2 Expand pins wired:
1. SD_CS--SD Cars chip selection pin
5. F_CS-- SPI FLASH signal

Quote
Code: [Select]
11PIN Standard wiring used IO:

1. VCC--Power supply (5V/3.3V)
2. GND-- Power supply (GND)
3. GND-- Power supply (GND)
4. NC--No connect
5. NC--No connect
6. LED-- Pick IO control back light off or PWM brightness control
7. CLK--SPI clock signal
8. SDI--Serial data input pin
9. RS--Command (RS=0)/ Parameter (RS=1)
10. RST--Reset pin
11. CS-- Chip selection pin


5 PIN Expand wiring used IO:

1. SD_CS--SD Cars chip selection pin
2. SD_MOSI--MOSI input
3. SD_MISO--MISO output
4. SD_SCK-- SPI clock signal
5. F_CS-- SPI FLASH signal

thanks in advance!

hi there...i need help...i am sorry but iam new to this forum so i am probably posting this qustion on wrong place but i gor to ask anyway...so my question is it possible to have 1.44" TFT LCD + touch( Adafruit 1.44" Color TFT LCD Display with MicroSD Card breakout - ST7735R) ...link is this: http://www.adafruit.com/products/2088  ????

Now please don't reply again unless you know the answer....


so now - 

can someone please answer my question?

Shravan_Anand_K

can you please give the hardware SPI interface clearly with pin numbers to arduino mega
and a sample code to load and display image form SD card
