Very nice clear display. Nice blue backlight, and relatively easy to get going with some tips. Ideal for my small project and seems like it is solidly built.
No instructions, so novices would need some help to get going - not quite a plug and play, but fairly close.
Using some google-fu, I tracked down the library and connections that made it work: the u8GLIB library http://code.google.com/p/u8glib/wiki/thelloworld a very handy post http://parenthetic.blogspot.co.uk/2011/12/hello-world-in-arduino-with-st7920-lcd.html and the datasheet http://www.dfrobot.com/image/data/FIT0021/ST7920.pdf I ended up with the following wiring: E = ESCLK = SCK = PB5 = D13 R/W = RW = MOSI = PB3 = D11 RST = PB0 = D8 RS = a0 = d1 = Data/Register select = D9 (in the picture I also linked PSB to GND (to select serial input). Don't know if this is required. and wiring BLA = A = 1.2k resistor to 5v BLK = K = GND VCC = Vcc = 5v GND = GND I then uploaded the 'Hello World' example from the u8glib, and uncommented and changed the header line from the defaults: U8GLIB_ST7920_128X64 u8g(13, 11, 9, U8G_PIN_NONE); // SPI Com: SCK = en = 18, MOSI = rw = 16, CS = di = 17 This got me showing the 'Hello World' on the display.
Excellent value display - would buy more.
