Hi!
In my board have pins to select (18,19) and (20,21).
So I can use with Henning's library or any other.
Best regards.

I have a question of my own the SD card is for logging and it is kept in the Ethernet card right? that is why you remove the pins off the TFT card so it disables it on the LCD which none of them work except for the new ones and you have to have the new sainsmart tft card to make it work

Because Henning's library not allow two devices on same pins.

Yes, because Henning's library uses I2C via software not hardware.
You can use any pin to RTC since that be exclusive for him.

actually, you can use the screen's SD card but it requires a small change in the code, go into setup.ino tab and change the SPI_FULL_SPEED to SPI_HALF_SPEED like below, but it will only work if the SD card works
Fernando had an issue with his new board not having the SD card built into it because his plan was to use the screens SD card reader, he figured this out a few days ago
Willie I was recalibrating my 7" screen just now and every thing on the screen was mirrored and backwards when I changed it from 5" to 7" problem went away
also with using the sainsmart LCD what did you pick as your screen under the calibration tool drop down above where you put in the X,Y and S on the http://www.henningkarlsen.com/electronics/t_cal_verify.php page

Very timely post I was struggling getting a good calibration tried 7 times, put in the default codes for the CTE70 worked straight away...
so got the basic code running on bare bone arduino mega with display adapter and screen.
Did not work with the IDE extension (like redtop's) or some of my wallwarts 9V and 12V. need to look at that...
Happy so far

Put the Ferduino on a Generic Mega clone and a Funduino Clone, with the same adaptor board and 7inch screen. I could run the mega clone from desktop USB but the Funduino started ok but the voltage power dropped so it froze (worked with 12v 1.5a wallwart but gets hot). Looks like these screens pull a lot of power and not all clones are made equal...
Redtop where did ypu get your shield that you could use your IDE cable ?

here is the coordinance I use with mine, it is for the CTE7 screen, it also works with my up-scaled Jarduino too, which I almost have all the bugs worked out of
Code:
#define CAL_X 0x00088FCAUL
#define CAL_Y 0x00410F6AUL
#define CAL_S 0x8031F1DFULhttp://www.amazon.com/gp/product/B00GGKDST8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
above is the shield I got that works with the IDE cable, I have 3 and all 3 work great, none of my other shields will work except plugged directly to the screen, not sure why but they all work with the IDE cable on the small screens, maybe the higher amp pull from the 7 inch screen has something to do with it

to get pasted the hot regulator, I used the 5v 6a power supply above, connected to the 5v pin and ground pin on the Mega, it works perfectly like that and no more hot Mega regulator whatsoever

Thanks for the info, equivalents on the way from fleabay as Amazon.ca does not have the listings... I will take me a couple of weeks to get the protoscrew shield soldered and figure out the best layout. Good thing we have a lot of tanks... Willie with the Jarduino comment you are going to make me buy another screen!
