Because those 4 bits are connected to LCD. I’m writing into the Port 0 ’s 4 – 7 bits. So first we need to send first nibble then followed by the second. Here everything is the same except the way of data writing. ![]() In initializing time we have to give 0x28 command. If we want to enable 4-bit mode we have to do small modifications in the normal method. In that time we can use this 4-bit mode and reduce the pin required for the LCD module. So we need to reduce the GPIO as possible. I’m doing one project which requires more hardware (sensors or etc). Then why we are going to 4-bit mode? This is the question that comes to every mind whenever I said 4-bit mode. LCD 4-bit interfacing with LPC2148 IntroductionĨ-bit mode – Using 8 data lines in LCD (totally 8 data lines are there)Ĥ-bit mode – Using only 4 data lines in the LCD moduleĨ-bit mode is already working and that looks awesome. ![]() Then only you can understand this strongly. Before we will start I would suggest you to read these topics.
