Any examples of projects which allow to control a LCD module over a i2c port ? (µC ATMEL 8051)
Are you makeing and I2C to LCD interface, or want to talk to and I2C LCD chip? for LCD software and I2C software. 1 Look on this web site 2 try 8052.com 3 try google 4 look at the threads here that should be an FAQ
Look at the Data Sheet for the LCD. Visit the manufacturer's website, and look for Applicaiton Notes, etc.
If your LCD has a parallel interface, then you could use I2C controlled IO-expanders to control the lines of the LCD. Personally, I'm using 2 PCF8574 IO-expanders (I2C controlled) to control my LCD. As such, I only need to spend two pins of the processor (SDA/SCL). And I can control lots of other I2C devices too, of course. --Geert
