Vor einigen Tagen haben wir Ihnen in einem Beitrag gezeigt, wie Sie selbsterstellte Zeichen wie z.B. Umlaute auf einem 1602 oder 2004 LC Display ausgeben können.

Die dort veröffentlichte Zeichentabelle beinhaltet jedoch bereits die Zeichen für "äöüß°µ" und "Ω". Für viele Anwendungen würden diese schon reichen.

Da sich die Tabelle jedoch nicht an den UTF-8 Standard hält, können diese Zeichen nicht ohne weiteres ausgegeben werden.

Über eine sogenannte Escape-Sequenz können wir jedoch den Chip direkt anweisen ein bestimmtes Zeichen auszugeben.

Displaying Temperature/Humidity on a I2C LCD  We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it uses less cabling (wiring)!

Scrolling text with I2C-LCD1602. I was looking for a simple project for beginners, newbies on Coding and MakerED. A looong time ago since we did a project with ONLY four (4) wires, isn't it! Well here is one which is very easy to create, a "Scrolling text on a LCD1602 with "I2C-Bus".

This tutorial demonstrates how to use our FC-113 IIC/I2C Serial Interface Adapter Module For 1602 LCD Display.  These serial interface modules simplifies connecting an Arduino to a 1602 Liquid Crystal display using only 4 wires.  This module uses the PCF8574T IC chip.

TIP for those WHO bought <===> https://www.amazon.de/dp/B079T1BW6T/  on #Amazon <==> from #AZDelivery: The #I2CAddress which I got delivered was "0x3F" and NOT "0x27, 0x38"!!; Check the I2C Address with this #Sketch <===> https://playground.arduino.cc/Main/I2cScanner  <===> SDA <==> PIN 4 / SCL <==> PIN 5 on Arduino

Graphics Primitives by Phillip Burgess
Each device-specific display library will have its own constructors and initialization functions. These are documented in the individual tutorials for each display type, or oftentimes are evident in the specific library header file. The remainder of this tutorial covers the common graphics functions that work the same regardless of the display type.

The function descriptions below are merely prototypes — there’s an assumption that a display object is declared and initialized as needed by the device-specific library. Look at the example code with each library to see it in actual use. For example, where we show print(1234.56), your actual code would place the object name before this, e.g. it might read screen.print(1234.56) (if you have declared your display object with the name screen).

Introducing 4D Systems' All New Workshop4 IDE Supports multiple development environments, to cater for different user requirements and skill level. Workshop4 is a comprehensive software IDE for Microsoft Windows that provides an integrated software development platform for all of the 4D family of processors and modules.

The IDE combines the Editor, Compiler, Linker and Downloader to develop complete 4DGL application code. All user application code is developed within the Workshop4 IDE. Workshop4 includes four development environments, for the user to choose based on application requirements or even user skill level. Designer This environment enables the user to write 4DGL code in its natural form to program the display module. ViSi - Genie An advanced environment that doesn’t require any 4DGL coding at all, it is all done automatically for you.

Simply lay the display out with the objects you want (similar to ViSi), set the events to drive them and the code is written for you automatically. ViSi -Genie provides the latest rapid development experience from 4D Systems. ViSi A visual programming experience that enables drag-and-drop type placement of objects to assist with 4DGL code generation and allows the user to visualise how the display will look while being developed.

Serial This environment is also provided to transform the display module into a slave serial display module, allowing the user to control the display from any host microcontroller or device with a serial port.

In this Arduino LCD Tutorial we will learn how to connect an LCD (Liquid Crystal Display) to the Arduino board. LCDs like these are very popular and broadly used in electronics projects as they are good for displaying information like sensors data from your project, and also they are very cheap.

You can watch the following video or read the written tutorial below.

Well, I made some searches on the internet and I found the right answer on a forum about this error, which says that one should scan the I2C Address of the device and replace the “lcd.init();” by “lcd.begin (0x3F,16,2);” whereby “0x3F” is the I2C Address of my LCD1602/I2C module. I scanned to find out the I2C Addess with this sketch, please check here:

Arduino datalogger project that logs: date, time, temperature and humidity on SD card. In this project the DS3231 chip will be used to maintain the time as well as the date and the DHT22 sensor to detect the relative humidity and the temperature. Two buttons are used to set time & date and LCD to display all data.

I purchased this Arduino LCD-Keypad shield from Amazon and it had terrible documentation. I made this video for anyone else looking for the pinout of this v1.0 board.

This program allows you to create bitmaps and fonts, and transform them to "C" source format for embedded applications.

The transformation of the images to the source code is made by using templates. Therefore, by modifying the templates, you can change the format of the output within certain limits.

SO, as I got my new Super Starter Kit UNO R3 Project I am playing around a bit with it. In my previous post WE were wiring and testing a LCD-Display and coding to display a bit text on the LCD. That was actually very easy, so lets try out now some “Sensors“, e.g. a Temperature/Humidity Sensor and a Ultrasonic Sensor to measure distances. The measured values of those sensors will get displayed on the LCD-Display.
