ESP32 + 20x4 LCD + backpack + I2C. by angus_grant on Tue Nov 05, 2019 8:12 pm . Hi, I have a 20x4 LCD + backpack which connects up to an Arduino correctly and displays correctly. It seems the 5V pin on the ESP32 cannot. I2C is sometimes referred to as 2 wire interface or TWI. All the Arduino board have at least 1 I2c socket which you can attach any peripherals that use I2C. examples are LCD with I2C module, Matrix LCD, 7 Segment Display, Real Time Clock modules, PWM(Pulse with Modulation Module) any modules and device that support I2C can be used in Arduino
By default (no code) it seems the LCD will have 1 line of 16 solid squares. When using address 27 in my code, the LCD will change to 2 lines of 16 squares (see photo below). The code also calls for the backlight to flash 3 times, which works. However I cannot get anything but 2 lines of squares. (Full code is at the bottom of this question). I'm using the LiquidCrystal_I2C library by F. Articles Related to 1602A LCD Display I2C Serial Interface (Arduino) Multiplexing vs. Charlieplexing : Basics & Example With Arduino.

In this tutorial we are going to interface LCD 20×4 Display with STM32 using I2C. I am using STM32F103C8 microcontroller and I2C device is PCF8574 with the slave address of 0x4E.. You can use the same code for any other LCD display Type (i.e 16×2, 16X4 etc), except the DDRAM addresses.You can google the addresses for your LCD Type The next step is to download and install the Arduino I2C LCD library for use with the backpack. First of all, rename the LiquidCrystal library folder in your Arduino libraries folder. We do this just to keep it as a backup. If you're not sure where your library folder can be found - it's usually in your sketchbook folder, whose location can usually be found in the Arduino IDE.

Grove - 16 x 2 LCD is a perfect I2C LCD display for Arduino and Raspberry Pi with high contrast and easy deployment. 16x2 means two lines and each line has 16 columns, 32 characters in total. With the help of Grove I2C connector, only 2 signal pins and 2 power pins are needed. You don't even need to care about how to connect these pins. Just plug it into the I2C interface on Seeeduino or. THE CODE. In this tutorial we will be using both the I2c LCD Backpack at address 0x27 and the I2C Expander at address 0x20. We have a 12 keys keypad connected to the I2C Expander module P0 to P6 pins. So instead of using 7 Pins on the Arduino, were's using the I2C protocol and using only 2 Pins to read the Keypad as well as display the results on the LCD screen.. I2C Address: 0x27 or 0x3F; Works with Arduino Uno and Mega 2560 boards; Working voltage: 5V DC; This IIC/I2C/TWI Serial 2004/20x4 LCD Module Shield for Arduino Uno/Mega2560 displays white contents on an elegant blue.

You will need an updated I2C LCD library, the original one I couldn't get to work but this one does seem to work - LiquidCrystal_I2C-master. You will need to import this into the IDE as usual. Now my example below required the I2C address to be changed to 0x3F, a lot of the example I have looked at are 0x2 4. The line lcd.begin(20,4) shows this is for a 20x4 LCD, and not an I2C version LCD. 5. Please confirm what pin on the lcd goes to what pin at the Arduino, to verify the connections. Please try the code below, and advise if you get anything. *** You may need to wind down the contrast until the top line of blocks is just visible. ** I follow the code given to upload to my NodeMCU that connected to I2C LCD 20X4.
