I am currently writing a driver for this LCD **broken link removed** and it uses the ST7036 driver http://www.sitronix.com.tw/sitronix/SASpecDoc.nsf/FileDownload/ST7036936139/$FILE/ST7036-V17a.pdf
Now the datasheet that they provide for the actual LCD is useless, I cannot figure out how to set the contrast. 'drive supply voltage' I'm assuming this means pull V0-V4 high, I've done this and tried enable/disabling the internal voltage follower, changing contrast from 0-15, I've tried this with the V0-V4 lines tied high/low and even with an external voltage follower.
Does anyone have any idea how I should wire this up and then what commands I should send the LCD so that it isn't entirely black or off?
Also I'm using a 3.6V supply, I2C interface on a PIC 24.
Also if I pull out the V2 and V3 wires and plug them in quickly it shows the text I've sent to the display for about half a second, then it dissapears or goes black again.
