TcUnicode Font format documentation
TcUnicode is a font format suitable for the presentation of a larger number of glyphs from different Unicode blocks. On most boards the size difference to Adafruit fonts is relatively insignificant. The advantage being that you can have fonts with glyphs from multiple unicode blocks efficiently. TcUnicode rendering is also compatible with Adafruit fonts, so you can use both and...
Text pipelines for drawing with tcUnicode
TcUnicodeHelper uses a text pipeline to draw onto the display. Text pipelines are how it supports so many library options, it is an interface that must be implemented in order for tcUnicode to be able to draw onto a device. It has the minimum set of functions for drawing text. Method drawPixel - takes the x and y location we want...
Embed Control developer version for controlling and monitoring Arduino
There are two versions of Embed Control desktop UI, the first is built into TcMenu Designer and is aimed at developers and more advanced users that fully understand the menu tree, and may want to create customize views. Gradually, we're moving toward App Store deployment for most platforms. TcMenu Designer runs on most desktop systems and can monitor and control embedded...
Control embedded menu application from browser - embedCONTROL.js
Instead of the desktop version, on Raspberry PIs you can serve a React.JS based single page web application that needs no installation. It works on a wide range of mobile phones, desktop and tablet devices. It is not supported in the Arduino or mbed environment directly at the moment. Using the deployed app To open the app, simply browse to the...
PicoSDK with OLED using UTF-8 tcUnicode fonts
Using the Native C++ fork of the Adafruit GFX library you can control an OLED display using UTF-8 fonts on a PicoSDK or mbed board directly. Right now it supports SSD1306 and SH1106 displays using both I2C and SPI. With the help of tcUnicode it can also display UTF-8 text. Using tcUnicode you can generate embedded fonts which can be...
Arduino Game library for 20x4 display
Here we discuss a game library that provides an easy way to write games with 20x4 parallel display and a few micro-switches. There is quite a lot of stuff going on in this library, so I'd like to start slow and build up. First, let's start by taking a look at the parts needed to use this library: 20x4 display (other...
Low power Arduino menu using tcmenu library
In this article we'll discuss building a low power Arduino menu using tcMenu library. We will use a TFT screen and a rotary encoder connected to a PCF8574 device. The device will be SAMD MKR board. I've picked this choice purposely, because it's non-trivial, and requires a lot of digging to make sure power usage is a low as possible. Running...
Arduino 7 segment LED display tutorial
In this tutorial I show you how to connect a 7 segment display to an Arduino board. For a tutorial showing how to drive 4 or 8 digit displays see ( Arduino multiple digit, 7 segment display tutorial ). Firstly, we must know what type of display we have as there are two possible forms, common cathode and common anode. If the...
