Our extensions to Adafruit_GFX for better performance
We provide a few extensions to Adafruit_GFX that improve performance by buffering the display and therefore preventing flickering and repeated operations on the same display area. Canvas support In addition to the standard Adafruit_GFX library that provides a monochrome canvas, we provide a 2bpp (bit per pixel) and 4bpp canvas class that allows you to draw to a buffer in memory...
GxEPD2 eInk display plugin for tcMenu
In this guide we discuss the GxEPD2 eInk display plugin for tcMenu, showing how to use and configure it for menu use. From an API/interface perspective, GxEPD2 is roughly equivalent to Adafruit_GFX, but with some additional features and optimizations for eInk displays. You'll need to install the GxEPD2 library from the Arduino library manager before you can use it with tcMenu....
Touch screen menu calibration
There are several touch plugins in TcMenu and they all have support for controlling calibration and orientation. The calibration UI is presently at preview quality although works for many cases. Below is an image showing the common options to most touch plugins. Touch screen calibration The touch screen calibration option provides a very simple UI and calibration load and save feature...
Using SSD1306 to generate a Uno / low memory multi level OLED menu
It is possible to build multi level menus with an OLED display on an Arduino Uno or other low memory board provided you use SSD1306Ascii instead of the U8G2 library, as it uses a lot less memory at the cost of some flexibility. We've tested it with regular I2C SH1106 OLED display units and it works absolutely fine. To use this...
Embedded Java OpenJFX screen rendering for Raspberry PI
Both EmbedControl remote and local work using the same UI components, and they can take a tcMenu Designer created menu tree and convert it automatically into a displayable graph. The "embedded/local" version does this with the menu tree embedded within it, while the "remote" version does so using a menu tree that it bootstrapped from a remote device. In order to...
XPT2046 / FT6206 touch screen input plugin
This touch screen input plugin supports both XPT2046 and FT6206 based touch screens. In order for this plugin to work correctly the right underlying library must be installed. These are described below: XPT2046 Paul Stoffregen XPT2046 library , best installed from library manager. FT6206 Adafruit_FT6206 library , best installed from library manager When using this touch plugin, the concept of touching...
TcMenu - Touch pad sensor input plugin
Requirements Current support: ESP32 touch sensor hardware. Touch-pad sensor summary Touch-pad sensors check for button presses without an actual switch, instead the rely on a change in capacitance when the user touches an area (usually a small metal plate around the size of a finger. Given that this procedure is quite complex, it usually requires hardware support for such inputs, so...
TcMenu - Resistive touch screen input plugin
TcMenu resistive touch screen input plugin supports four wire resistive touch devices that are often fitted in front of color TFT displays. This plugin requires two ADC analog inputs, but note that all pins must be output capable. The connectors are often referred to as X+, X-, Y+ and Y-. In all cases X- and Y+ must be connected to ADC...
Using the Adafruit_GFX fork for STM32Cube, PicoSDK and mbed
In this guide we show how to use our Adafruit_GFX port for STM32Cube/PicoSDK/mbed to renderer menu items with tcMenu. This rendering driver for Adafruit_GFX is built into the core menu designer, meaning it's available out of the box when either mbed, PicoSDK or STM32Cube are selected. This fork of Adafruit_GFX library supports the following displays. OLED: SSD1306/SH1106 monochrome displays with...
TcMenu - Using U8G2 to render menus onto an OLED
In this guide we show how to use the U8G2 library to renderer menu items to an OLED unit with tcMenu. This rendering driver for U8G2 is built into the core menu designer download, meaning it's available out of the box. The U8G2 library supports a lot of different displays, with very different capabilities. This plugin concentrates on monochrome displays, mainly...
