I have wired it up to my Arduino Mega 2650 the same as in this picture:
and i am using this code to try and test it:
/*
Arduino TFT text example
This example demonstrates how to draw text on the
TFT with an Arduino. The Arduino reads the value
of an analog sensor attached to pin A0, and writes
the value to the LCD screen, updating every
quarter second.
This example code is in the public domain

#include <TFT.h> // Arduino LCD library
#include <SPI.h>
// pin definition for the Uno
#define cs 10
#define dc 9
#define rst 8
// pin definition for the Leonardo
// #define cs 7
// #define dc 0
// #define rst 1
// create an instance of the library
TFT TFTscreen = TFT(cs, dc, rst);
// char array to print to the screen
char sensorPrintout[4];
void setup() {
// Put this line at the beginning of every sketch that uses the GLCD:
TFTscreen.begin();
// clear the screen with a black background
TFTscreen.background(0, 0, 0);
// write the static text to the screen
// set the font color to white
TFTscreen.stroke(255,255,255);
// set the font size
TFTscreen.setTextSize(2);
// write the text to the top left corner of the screen
TFTscreen.text("Sensor Value :\n ",0,0);
// ste the font size very large for the loop
TFTscreen.setTextSize(5);
}
void loop() {
// Read the value of the sensor on A0
String sensorVal = String(analogRead(A0));
// convert the reading to a char array
sensorVal.toCharArray(sensorPrintout, 4);
// set the font color
TFTscreen.stroke(255,255,255);
// print the sensor value
TFTscreen.text(sensorPrintout, 0, 20);
// wait for a moment
delay(250);
// erase the text you just wrote
TFTscreen.stroke(0,0,0);
TFTscreen.text(sensorPrintout, 0, 20);
}
But all i am getting is a blue screen on the LCD when i plug it in and nothing changes even when i load the code on.
Any ideas? i don't have a shield is this the reason?
Ok thank you for the help, have just wired the screen up as instructions say and then moved onto the programming but i am getting an error coming up. I no this is most likely just me doing something wrong but what is it?
Oh think I downloaded version 0.01 will give it a go with 0.02 now is that the most up to date? And extracted it and but it in the library folder in the arduino program files
If Ucglib is installed correctly, it should also provide some examples in the IDE menus.
It should also be possible to install Ucglib via the IDE library install feature.
I have deleted 0.01 from the library and restarted everything but still not working for some reason. Is there anything else i have to do to uninstall it manualy?
Right just had another play and i hadnt uninstaled the library properly so i manualy deleted it exited arduino software started it up again and added 0.02 and the scetch complied and went onto the arduino!! great only problem is its still not working lol Do i have to have the SPI pins in for it to work? and is sdi (mosi) also know as data? and it says sck on my board instead of sclk is all this ok? if so think the board is blown/faulty
Not exactly sure about the meaning of your question: SPI is a protocol, that is used by the display. For sure the connection is required. But you can choose between HW SPI (= you must use specific pins of the Arduino Board) or SW SPI (use any pins and tell the library which pins are used)
