hi,

I wonder if anyone would have a library in C language for the LCD type SSD1803A of the Midas brand with i2c connection (4x20 characters). I use a 18f4680 Pic.

here is the link to the datasheet of LCD:
http://octopart.com/datasheet/mccog42005a6w-bnmlwi-midas-24879610-14421358

the link for the LCD screen:

I am an amateur help me please.

thank you in advance for your help.

You posted the exact same message in the Microchip forum and other sites under different names.
What compiler and version are you using?

One of the problems is lack of 'commands' in the datasheet. I couldn't see a list though there is a small 'program' to initialize the LCD.
There's only 1 line about the devices I2C address as well.
Maybe there's a better specsheet other than the one you 'link to ??
