In this post, I will explain how to send commands and data to LCD16x2. Fix Lcd Command 0x03 by changing the equipment, after a device was installed in your pc, particularly when the problem occurs. The PCF8574 converts the I2C signal sent from the Pi into a parallel signal that can be used by the LCD. There are a couple ways to use I2C to connect an LCD to the Raspberry Pi. To send command/data to 16x2 LCD we have to send higher nibble followed by lower nibble. The screen command is a terminal multiplexer, and it’s absolutely packed with options.To say it can do a lot is the granddaddy of understatements. With the support of LiquidCrystal library , we even can use LCD WITHOUT knowing the meaning of these pins. When you power up this circuit, you will see a series of square only on line 1 of the display. Normally, your code would set that address and "know"what it is by how many characters have been written, so the addressread feature is rarely needed or used.
