arduino mega 2560 3.2 tft touch screen & ethernet shield, Doesnt work need help

ok own arduino mega 2560 3.2 tft touch screen , lcd shield, bought ethernet shield , connected mega , ended white screen... if remove ethernet shield, tft display normal... idea why getting white screen when ethernet shield plugged in?


any great... been trying figure out fix past 3 days no luck...



this mega tft lcd screen got...

i haven't defined ethernet shield don't think matters tft connected stack anyways, if ethernet not being used... wouldn't tft still displays?

i have try'ed powering normal usb cable once uploaded sketch, unplug , plugged in external power supply of 12 v 750 ma ac-dc adapter , still getting white screen.

ok got fixed not sure if works... tft , ethernet shield connected no change needed... did added in :


#include <spi.h>
#include <ethernet.h>


and :

// initialize ethernet client library
// ip address , port of server
// want connect (port 80 default http):
ethernetclient client;



and works... display... can tell me how can test ethernet shield , see if connects internet or how set run? did connected boards , powering usb cable

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem
