Method1: Interfacing 16X2 LCD display module with Raspberry Pi Pico with out I2C adapter Required components (Bill of Materials): Product Name has pins for LCD backlight and contrast adjustments using potentiometer. It has 8 data pins for 8 bit data but we can also use 4 bit data mode which we are using in this example.

It has a separate library with instructions and commands, if you want to twerk with it to build anything advanced refer its datasheet here.Īs you can see from the above LCD display module pinout diagram the display is powered with VCC:5v and GND. So, to overcome this issue, an IC HD44780 which can process the data and commands from the microcontrollers and convert them into LCD meaningful instructions to display the data on it. So for every character all the 40 pixel dots are to be instructed weither to be lit on or off.Īs our 16X2 LCD display has 32 Characters, there should be 32X40=1280 instructions to be sent to display 32 characters on the display, which is a very complex task for microcontrollers. To make a character, pixel dots should be lit black according to the character shape and other pixels should be in off state. Each character is made with 5width x 8height pixel dots =total 40 pixel dots for one character. It can display total of 16X2=32 characters. So, lets know the process and coding to connect Pico board with 16×2 LCD display and same for 20X4 LCD display and display some simple text on it.Īs the name indicates 16X2, means it can display characters in 16 columns and 2 rows and LCD is the Liquid crystal Display. We can add WiFi to Raspberry Pi Pico to create a webserver but it moves towards very complex side.

Many latest Microcontroller boards are coming along with WiFi and Bluetooth which can create webservers to display the data on PC or mobile displays but the new Raspberry Pi Pico neither has WiFi nor Bluetooth, To play with projects and to display the output it has only 2 options to display the data either on Serial monitor or by connecting a LCD display or OLED display. In this quick tutorial, learn how to connect 16X2 LCD display module without I2C adapter with Raspberry Pi Pico board which requires lots of wire connections and also learn connecting Raspberry Pi Pico board with 16X2 LCD display module using I2C adapter which uses only 2 wires for data transfer and 2 wires to power up.
