die auf sainsmart verlinkte ist noch für die 0.23 für die 1.0.1 gibts eine funktionierende Library von adafruit
 http://github.com/adafruit/Adafruit-ST7735-Library

ich hab leider auch das Problem mit dem Flackern teilweise, aber auch nicht immer. es kommt definitiv nicht von der Beleuchtung. aber sonst komme ich auch noch nicht weiter.

sorry, i updated the post. but i deleted some errors because it was too long

Damit hatte ich mich auch schon mal rumgeplagt,das Programm ist relativ dürftig und wenns lief wurds nicht ordentlich dargestellt (Display flimmerte weils langsamer war als "clear" und neues schreiben). und die Libary nutze ich nicht mehr. Ich hab mir einfach eine eigene kleine auswertung geschrieben für die Tastenauswertung.

Ich muss später nochmal bei mir reinschauen was genau ich gemacht hab

Hello,
I buy a Display
http://www.sainsmart.com/module/lcd-module/tft-lcd-module/sainsmart-1-8-spi-lcd-module-with-microsd-led-backlight-for-arduino-mega-atmel-atmega.html
an try to use the Libary and Example Code from Sainsmart
http://www.sainsmart.com/zen/documents/20-011-920/TFT18.rar

i use Arduino IDE 1.0.1 and an Arduino UNO smd r3 (original)

wenn i try to check a example code there are many many errors

Now somebody why? wrong ide? wrong libary? Is anywere an running Libary?

Errors:

Thanks!

Danke Robi,
zzz = Tasten(); funkioniert // hab auch alles jetzt auf byte gesetzt

Danke!

Hallo Zusammen,
ich komme gerade nicht mehr weiter, folgende Fehlermeldung erscheint:

invalid conversion from 'byte (*)()' to 'byte' bezogen auf die 4. Zeile im Loop
auch lcd.print(Tasten); gibt mir eine Fehlermeldung
die Schleife byte Tasten(); wird zumindest ausgeführt(und "i" korrekt auf dem LCD angegeben)

Ich stehe noch recht am anfang und hoffe das ich nur nen blöden Fehler drin hab

Vielen Dank & Grüße,
Matthias
