My screen isn't displaying anything / my screen just displays two rows of solid squares If the backlight is on then see the next FAQ If the jumper is missing check the anti-static bag your module was shipped in. Our modules are shipped with this jumper fitted but it is possible for it to shake loose during shipping. This purpose of this jumper is to connect the 5V power to the backlight. If your backlight isn't on then check that there is a jumper fitted across the two pin header labelled 'LED' on the back of the module. If text on your module is hard to read this is normally caused by one of two things.įirstly, this module requires the backlight to be on for text to be readable. Under normal conditions text should be very clear and visible. If you have downloaded a version from elsewhere please also remember to delete it from your Arduino library folder(s) otherwise the Arduino IDE may still continue to use it.

For our screens you always use the version available for download in this post. Normally this is caused by one of 3 things, a bad or incorrect connection to the I2C interface on the module, an incorrect I2C address (for our modules the default address is either 0x27 or 0x37), or by far the most common cause is using an incompatible version of the LiquidCrystal_I2C library. If your display is showing this then it is a sign that your sketch is not initialising the module correctly for some reason. It is normal for the module when first powered up to display a row of solid squares as show above. My screen just displays one row of squares along the top line. * Make sure the backlight is turned on */ Uncomment one of the lines below depending on Note that the displays will have a default I2CĪddress of either 0x27 or 0x3F. Reference to in your comments if you redistribute this code.

You may copy, alter and reuse this code in any way you like but please leave PIN 4: SCL - Connect to Arduino analogue PIN 5 PIN 3: SDA - Connect to Arduino analogue PIN 4 Run this program you should see a greeting message appear on the display. This code also demonstrates the correct pin assignment for the LCD. Which can be downloaded from the modules section of our support forum at the To use this module you will require the appropriate library
INCONSISTENT EXTFS ARCHIVE HOW TO
This is a simple example of how to use the Hobby Components I2C LCD module Please ensure when the LCD is installed in your application that no external object is applying pressure to the back of the module.ĪRD_LCD_HCARDU0023_I2C_Hello_World_Example.pdeĬode: Select all /* FILE: ARD_LCD_HCARDU0023_I2C_Hello_World_Example.pde If pressure is applied to the I2C daughter board it is possible for it to bend and come contact with the LCD module. This may require adjusting for the screen to display text correctly. The module has a contrast adjustment pot on the underside of the display. If there are no pads the default address will be 0x27. If there a 3 sets of pads labelled A0, A1, & A2 then the default address will be 0x3F. To determine which version you have check the black I2C adaptor board on the underside of the module. These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. If you plan to use this with an Arduino board you can download a compatible library and example sketch (see below).įeatures 64mm x 14mm LCD display, supports IIC / I2CĪpplication DIY Arduino based project.
Contrast adjustment is also provided by the daughter board via a potentiometer. In total the module only requires 4 wires including 5V power and GND.
INCONSISTENT EXTFS ARCHIVE SERIAL
This means it can be controlled with just 2 I2C serial data pins (SDA & SCL) and so requires far less digital IO pins when controlled from a microcontroller. It also includes a serial I2C/IIC adaptor board pre-soldered to the back of the LCD. This 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight.
