micro bit lcd screen made in china

Micor:bit has variety of programming methods like mbed, micropython, typescript and other programming methods, as well as code online websites which are abundant.

Place the block before send display data. You can choose the position, color and size. For the screen, (1,1) is on top-left, and (160,128) is on bottom-right

The Kitronik :VIEW Text32 LCD Screen for BBC micro:bit is a character LCD showing 32 characters (2 lines of 16 characters). The :VIEW Text32 also breaks out the BBC micro:bit pins to edge pads (excluding pin14).

The bottom edge of the board has a replication of the BBC micro:bits own edge connector, this allows you to plug the :VIEW Text32 into any board that the micro:bit itself can be slotted into. This is great news if your project outputs strings of text and numbers that previously would have slowly scrolled across the LED Matrix.

The board has been designed so that the BBC micro:bit can be slotted into the edge connector on the top side of the PCB. No extra tools are required for installation, the board is supplied and ready to go - plug and play or work.

Get meaningful text readouts from your microbit projects with the Kitronik :VIEW Text32, a 32 character 2 line display that has a microbit style edge connector.

The Kitronik :VIEW Text32 character LCD, for those times when the LED Matrix and/or external LEDs aren"t delivering adequate visual feedback from your microbit project. The :VIEW Text32 is a character LCD showing 32 characters (2 lines of 16 characters). The :VIEW Text32 also breaks out the BBC micro:bit pins to edge pads (excluding pin14).

On the back of the :VIEW Text32 is a 3 x AAA battery holder to provide power to the :VIEW Text32, the attached micro:bit, and the replicated edge connector. There is a power switch for turning the battery supply on and off. The replicated edge connector can supply 90mA (as per the normal micro:bit)

Kitronik has produced a set of custom blocks for the Microsoft MakeCode editor. To add them click on the cog icon in the top right of the editor, then; select Extensions from the drop down menu, type and enter Kitronik into the search bar and select the :VIEW Text32 tile from the list. The custom blocks will now be added to the editor and can be used in your code.

Overhere we will show you what is the I2C LCD 1602 Display and how it works, you can follow the next lesson to get how to use the I2C LCD 1602 Display with the micro bit.

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. When they are connected to a microcontroller (such as Micro bit for example), these displays require virtually many connection PINs occupying practically almost all available IO and leaving the multiprocessor few outputs for any other devices and sensors. This problem has been solved thanks to the communication on the I2C bus.

The LCD1602 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). I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.

The blue potentiometer on the I2C LCD1602 (see the figure below) is used to adjust the backlight  for better display.And there is a jumper on the board, if you take away this jumper , the 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. After the program is successfully downloaded to the board, connect the USB cable to the USB port on the expansion board, ensure the LCD display can work perfectly.

If you are not familiar to make code, don’t worry. At first, you can enter this link: https://makecode.microbit.org/reference to get the reference of microbit block.

After downloaded this code to your micro bit, pull out the USB line and insert the USB line to the expansion board, you will see “OSOYOO”，”Hello” on the LCD screen, then the entire screen will be full of random numbers.

Micro:bit is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The BBC gave away the computer free to every year 7 child in Britain starting from October 2015(around 1 million devices).

The Micro:bit Foundation aims to put the device into the hands of 2 million children in the U.S. & Canada by 2020. "The goal of the micro:bit is to give educators and parents an easy-to-use tool to teach the basics of computer programming and inspire students to imagine, invent and innovate." said Hal Speed, Head of North America at the Micro:bit Foundation.

In Singapore, the government will be putting Micro:bit in the palms of up to 100,000 school-going children and adults to instill passion for technology to better prepare for a digital future.

We designed the Sino:bit based on the Calliope mini with permission of the Calliope mini project. While several modifications are planned, the first was to upgrade the LED matrix from 5x5 to 12x12. This allows for support of Chinese, Japanese, Hindi, Arabic and other non-Latin character based languages. Without this, the vast majority of the World"s children cannot experience the thrill of that first "Hello World" in their own language.

"Sino:bit has now officially been certified as open source hardware by the Open Source Hardware Association. Congratulations! Your UID is: CN000001. Your hardware is now listed in the certification directly located here: http://certificate.oshwa.org/certification-directory/ "

Instead of turning individual LEDs on or off, as above, you can display an image directly to the screen or show text and numbers on screen using the show number and show string functions.

The micro:bit runtime keeps a representation of the state of all 25 LEDS in memory. This state is known as the “display buffer” and controls which LEDs are on and which are off. The plot, unplot, and point functions access the display buffer directly. On the other hand, the functions that show an image, number, or string overwrite the buffer completely. To illustrate this, first try running this code sequence

The new micro:bit enhance more way of learning with the built-in speakers, microphone and touch sensor on the all new micro:bit v2, there are many other cool stuff you can do with this new micro:bit v2.
