I bought some Chinese monochrome LCD modules with TM1727 4*40 LCD driver (I2C with RAM Mapping). I am trying to adopt any I2C Arduino library but without success. http://www.titanmec.com/download/file/a ... M1727.html Does anybody have the opportunity to work with this chip? I am...

In the main function, first of all we will initialise the I2C driver. Remember that this must be done before we call any LCD related functions, since the LCD functions uses the I2C. Then we will initialse the LCD. We will put the cursor at 0th Row and 0th Column and print “Hello...
