I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work.

We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and text display features. It can replace the serial monitor of Arduino in some place, you can get running informations without a computer.

More than that, we also develop the dedicated picture data convert software (bitmap converter)now is available to support PC platform of windows, Linux, Mac OS. Through the bitmap convert software you can get your favorite picture displayed on I2C_LCD, without the need for complex programming.

If you are having issues uploading the most recent default firmware to the smaller (10mm) serial enabled 7-segment display via the Arduino IDE, try using the older version of the firmware in the GitHub v3.1 branch. This is the same firmware that is used in our production department.

Having issues with the serial UART example, SPI, and/or I2C example code? You could try a factory reset with the microcontroller on the 7-segment serial display by:

If you believe that the smaller (10mm) 7-segment serial display has corrupt firmware, you could also reinstall the Arduino bootloader. You could use an AVR programmer to reflash the ATmega328P on the serial enabled 7-segment display.

If you are using the latest default firmware from the master branch, make sure that you have the correct “DISPLAY_TYPE” defined in the Serial_7_Segment_Display_Firmware.ino code. This is on line 39 of the GitHub master branch. Just change OPENSEGMENT to any of the other hardware layouts. Otherwise, the display with show "0000" as explained in the Arduino Forum: Arduino Uno - 7 Segment Shield Problem .

If you have issues using the serial enabled 7-segment display where the LEDs flicker and display random numbers, it could be the way that you wrote your code. There was one case that tech support encountered where this happened after using a sequence of commands to clearing the screen, setting the mode, setting the brightness, and adjusting the cursor.

Testing with a 5V RedBoard, the major issues that seemed to be fixed was removing the clearDisplay() function and adding a delay between setting the brightness and your cursor position. The flickering may be due to clearing the screen and writing back on the screen in your main function. By avoiding the clear screen function every time my main function looped back, the serial enabled 7-segment displayed the counter better. By adding a 1ms delay, the serial enabled 7-segment stopped displaying random numbers and flickering. It"s possible that the serial enabled 7-segment display does not have enough time to set the brightness for the entire display. Adding the delay probably helped in completing the function before moving onto the next command.

The value 0x00 is not specifically defined so it could be a char(NULL), int, or a byte. The compiler doesn"t understand what you are referring to. To work around this, try saving the byte into a defined variable and using it with the Serial.write() function similar to this:

The Arduino I2C library uses 7-bit addressing [ https://www.arduino.cc/en/reference/wire ]. The library ignores the last bit because there is a function for reading or writing. Other development boards outside of the Arduino ecosystem may require different addressing techniques. This was stated briefly in the I2C example code:

If you are using a different language other than Arduino, you will probably need to add the Read/Write bit to the end of the address. This means the default read address for the OpenSegment is 0b.1110.0011 or 0xE3 and the write address is 0b.1110.0010 or 0xE2.

Now, with only 3 pins from microcontroller, you can display message on this LCD. Compared to parallel LCD which required at least 6 pins of I/O, this LCD offer more cost effective solution. The LCD display is two lines by 16 characters and provides basic text wrapping so that your text looks right on the display.

A regular LCD requires a lot of wires (parallel interface) to be connected with a Microcontroller.The Serial LCD  backpack built on PCF8574 IC uses the I2C bus to convert  the parallel interface to a serial one.This needs only2 wires SDA & SCL , apart from the power connections.

The blue preset is to adjust the contrast of the LCD. The black jumper on the left is to enable the Backlight of LCD. The I2C device has a HEX address by which a microcontroller can communicate with it.This is set by the 3 bits A0,A1 ,A2 .If no jumper is present , it is HIGH &  a jumper means LOW. By default all the 3 jumpers are open . ie., A0,A1 A2 all are 1s.

lcd.setBacklightPin(HIGH);  makes the P3 pin go High, which turns on the NPN transistor.This provides GND to the LED pin of LCD As the other LED pin is already connected to Vcc through the jumper , the LCD backlight glows.
