Sainsmart TFT LCD 7" 800 x 480 [SOLVED]

[Jorge Cardenas]

Hi, I'm looking for help with a Sainsmart TFT LCD 7" 800 x 480.

I've a Ferduino mega 2560 and I have preloaded the Feduino_with_webcontrol_beta7_0 version.

I've the changes recommended by Fernando to work with TFT 800x480. Remove the resistor that is next to the backlight control and did the wiring on the back of the plate with a 10 ohms resistor to Gianluca style but when connect the screen directly to Ferduino the image looks perfect but the touch does not work.

I will attach some pictures of the modifications and the pinout of the screen.

Congratulations to Fernando for the excellent work he did with the Ferduino plate.


I apologize for my English.

Regards.

Hi!

Welcome Jorge!

Are you using this configuration for touch?

Code: Select all

UTouch      myTouch(7, 6, 5, 4, 3); // For Ferduino Mega 2560

Best regards.

Hi Fernando, I tried with that configuration but still not working.

When I turn on the Ferduino and the main image is displayed, touch the screen and the menu appears but can not select anything.

I have an Arduino Mega 2560 R3 preloaded with Feduino_with_webcontrol_beta7_0, I connected the screen with the shield and everything works normally.
