The integration of an LCD display greatly facilitates the interactivity of the project you are developing, allowing the user to directly read some output parameters. These values can be either a simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the Arduino is performing. However, these displays have a small problem.

This problem has been solved thanks to the communication on the I2C bus. The LCD display has an integrated microchip that manages this type of communication, and then all of the input and output information are limited to only two PINs excluding power supply. Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3. And there is a jumper on the board, if you take away this jumperthe backlight will aways be off.

Because the output power of the micro bit is limited, please connect the USB cable to the USB port on the micro bit when downloading the program.

Either copy and paste, or re-create the following flat dark earth 308 upper into your own MakeCode editor by clicking the open icon in the upper right-hand corner of the editor window. You can also just download this example by clicking the download button in the lower right-hand corner of the code window.

If the screen is not bright, please check the wires. If the screen is bright, but you do not see the above results, please check you I2C address. DownLoad Url osoyoo.

The backlight is on and turns of and waits to turn back on but it never shows the text. You must be logged in to post a comment. Login Register.

This library is based off of a C version that I wrote, which can be found here also look for files in the same directory which start with lcd.

Nic created a C port of this library which can be found here. The boards usually mount behind the LCDs and are commonly called "backpacks". The most commonly used display is a "" or "16x2", which features 16 columns and 2 rows of characters.

Each come in various backlight and pixel colours. There are also variants of the code for MicroPython. The photo shows Orange connected to P I used a SparkFun level shifter this particular model is no longer available. The circuit allows for digitally controlling the contrast via PWM and also controlling the backlight brightness via PWM. Japanese, European and Custom. Test which you have using:. You can specify any pattern for these characters. To design a custom character, start by drawing a 5x8 grid.

I use dots and hashes as it's a lot easier to read than 1s and 0s. Draw pixels by replacing dots with hashes. Where possible, leave the bottom row unpopulated as it may be occupied by the underline cursor.

To display the custom characters, use putchar with chr 0 through chr 7. Characters are displayed by reference. Once you have printed a custom character to the lcd, you can overwrite the custom character and all visible instances will also update. This is useful for drawing animations and graphs, as you only need to print the characters once and then can simply modify the custom characters in CGRAM.

Are any problem to drive from the 5V output of WeMos? Has it enough current or should it be powered separately? Thanks in advance. Questions: 1. Did anybody make it working with WeMos D1 Mini? Will it work in both i2c and GPIO modes? I cannot read the sign of that diode on my device, but some datasheets say B, which is a 1 A Schottky diode. I recommend to add an an additional buffering capacitor at the 5V. Yes, using various HDs, 08x2, 16x1, 16x2, 16x4, 20x4, blue and yellow.

The 08x2 pin arrangement does not mate with the I2C backpacks as the pins are on 2 rows. You can still use the backpack, but you will need to use some wires instead. My blue and green 20x4 LCDs: 36mA with backlight on, 5. Many thanks dhylands, mcauser, and ernitron. Not sure that is really needed or not.

You do not have the required permissions to view the files attached to this post. On some websites I read that the I2C address "0x27" can be wrong, and I have to try another one I2C requires them.

How those are wired up determines the lest significant 3 bits of the I2C address. On my board, these address lines are pulled up to 5V via resistors on the boards, and there are solder pads that can use to connect them to ground instead.
