Moin,
ich bin gerade dabei, mir für mein Aquarium einen Computer zum erfassen mehrerer Werte wie Temperatur, Ph-Wert usw. zu bauen.
Soweit hab ich mich mit dem Codieren durch learning by doing gut zurecht gefunden und alles so hin bekommen wie ich es wollte. Nun möchte ich auf das im Titel erwähnte Display umbauen,
ich bekomme es aber einfach nicht zum laufen. Es ist ein Komplettset von Ebay: 7 Zoll TFT LCD Resistive Touch SSD1963 Schild für Arduino fällig, MEGA 2560 Bibliothek | eBay
inkl Testcode.
Mehr als die Hintergrundbeleuchtung bekomme ich aber nicht an.
hat evtl. jemand Erfahrungen mit dem Display und kann mir dabei helfen ?
Code der dabei war:
#include <UTFT.h>
// Declare which fonts we will be using
extern uint8_t SmallFont[];
// Set the pins to the correct ones for your development shield
// ------------------------------------------------------------
// Standard Arduino Mega/Due shield : <display model>,38,39,40,41
// Remember to change the model parameter to suit your display module!
UTFT myGLCD(SSD1963_800480,38,39,40,41); //(byte model, int RS, int WR, int CS, int RST, int SER)
void setup()
{
randomSeed(analogRead(0));
// Setup the LCD
myGLCD.InitLCD();
// -------------------------------------------------------------
pinMode(8, OUTPUT); //backlight
digitalWrite(8, HIGH);//on
// -------------------------------------------------------------
myGLCD.setFont(SmallFont);
}
