The first few commands should be similar to how they have provided in the datasheet, but after setting the 4 bit mode (after display initialisation in the code), you can modify the registers as per your need. For example if you want to set the blinking cursor, or cursor moving direction...
The first step in coding the LCD is initializing the LCD connected by giving the commands as input through the data line D4-D7 in the form of Nibbles. For initializing the LCD following a specific reset sequence should be given and then initialized to follow the 4 bit mode. Place the by...
