I have started to play with the arduino a short while ago. However, I encountered an obstacle.
My arduino kit arrived with SG12864J4 LCD screen, and I am unable to get it to work. First, I tried wiring it via the tutorial even though I have a 20 pin connection, like that:
Then, I downloaded both libraries: GLCD v3 and ks0108, and I wired the arduino according to the guide which appears in glcd library. My LCD screen is located under type B boards.
I uploaded the ready-made software 'Hello World', but nothing happens. Not even get a backlight.
However, if I connect 5V and GND to pins 19 and 20, I only get a backlight.
Thanks in advance
