Generate custom embedded app with mobile integration

By dave on October 12, 2020

Summary We can build an embedded and mobile application based upon tcMenu in a very short amount of time. Our application infrastructure makes it possible to offer a simple UI that can be controlled using a white label version of embedCONTROL over BLE, WiFi, Ethernet, Serial or many other protocols. Along with all the open-source display options, we also have display drivers for native graphics built into STM32F mbed boards, and can easily create other custom display drivers if needed.

TcMenu and IoAbstraction consultancy quick start

By dave on November 30, 2018

If you’re thinking of using tcMenu, IoAbstraction or any other of our libraries on a commercial project, then we offer training and support to get you started quickly. It can be much more affordable than you first think too. Especially when you factor in the saved time, and reduced risk. Along with this we also have extensions to both of the libraries that are only available under a commercial license. These improvements offer significant performance gains over the open source versions, while remaining very compatible.

TcMenu - Overview and quick start

By dave on April 20, 2018

Above: getting started video showing how to use our menu library with Arduino. Link to the Getting started with tcMenu Slides (from youtube video). TcMenu is a complete menu solution for Arduino and mbed platforms that supports a wide range of input / display devices, and can be remotely controlled using embedCONTROL or using our Java Remote API on supported hardware. This page walks you through using tcMenu Designer to design and build an embedded application.

Rendering using themes - properties, grids and icons

By dave on September 5, 2021

From TcMenu 2.0 onwards all display plugins except Uno are customized using themes and render using properties and grids. For these renderers you can override the way that they draw in several ways. Firstly, lets start with a discussion of what’s possible. Firstly, icons can be used in place of actionable items, they are setup on a per menu-item basis. The colors, padding, orientation, and font for a menu item are now customisable at three levels: Default, Sub-menu, Item.

Setting up IO-expanders in the menu designer

By dave on August 28, 2021

Setting up IO devices has been made much easier as of V2.2 of the designer software. you can now directly edit the IO expander configurations directly within tcMenu. When we discuss IO devices we are talking about IoAbstractionRef objects that refer to either device pins, or any other device such as I2C expanders or shift registers from the IoAbstraction library. In order to manage the IO Expanders that are available within a project you can do so from the Code menu -> Show Io Expanders.

Integrating EEPROM support into menu applications

By dave on August 14, 2021

IoAbstraction EEPROM support can be integrated into your menu application, it can be used to load and store menu item values, authentication and also choice menu items that are using EEPROM storage. Menu Manager makes it very easy to save values to EEPROM between runs. Each menu item can optionally have a storage point in the EEPROM area (-1 / 0xffff means not stored). Any items that have a valid EEPROM address will be persisted upon calling the save function on menuMgr, and similarly, will be read back by calling load.

Securing sub-menus and remote connections with an Authenticator

By dave on August 14, 2021

You can secure both sub-menu items and remote connections using an Authenticator. In summary, when an authenticator is present on menuMgr any attempt to show a secure sub menu will result in a dialog asking for the pin; only proceeding to display the sub menu if the pin matches the on in authenticator. In addition, all remote/IoT connections will only be allowed if the authenticator approves the connection. An example of the secure sub-menu pin entry screen is below:

Taking over the display from a renderer

By dave on November 12, 2020

TcMenu allows you to take over the display from the renderer very easily, once you own the display, you will be called back at regular intervals by the rendering class, and it is your responsibility to update the display at this time (if there are changes that require redrawing). You should never update the screen outside of these callbacks, as doing so would interfere with TcMenu rendering. There are two choices in this case, a functional approach based on providing a callback function, or an object oriented approach, where you provide an extension of CustomDrawing to the renderer.

MenuManager and menu iteration

By dave on October 2, 2020

MenuManager contains the functions to manage menu items, there is a global instance of this class called menuMgr. Here we present the most commonly used features, check out the reference docs for more details. There are a lot of iteration helper functions that can be used to navigate through menu structures. These are described further down the page. The following two reference documentation pages extend on the information here: Menu iteration reference docs MenuManager reference docs EEPROM support in menus Enabling next and back functionality To enable next, back or both, you provide the pin onto which you’ve connected the button for this function.
