Troubleshooting and mock objects for testing
Troubleshooting IO issues using LoggingIoAbstraction Within the MockIoAbstraction.h header there is an implementation of BasicIoAbstraction that delegates through a logging layer. If you are having difficulty determining what your code is sending and receiving, this could be useful. You simply introduce the logging abstraction between your regular abstraction and the device you're having trouble with. For example: Mock objects for use...
TcMenu - Overview and quick start
Menu library and designer for Arduino and mbed TcMenu is a modular, IoT ready multi-level menu library for Arduino and mbed supporting many input, display and IoT / remote interfaces. It makes presenting configuration, status and operational information much easier. First, you design your menu structure using the designer UI, then using the code generator you convert your menu structure into...
Timed blink - IO Abstraction library example
Timed blink is a version of well known Arduino blink example that is shipped with the standard IDE, but is redesigned to use the Abstraction and timer library. Example circuit for the code is exactly the same a blink, and if you use the inbuilt LED pin (which it does by default) then there's no need to build any circuit...
Multi language locale based menu for Arduino and mbed
TcMenu 4.0 onward supports multi-language menus based on resource bundles which are effectively properties files containing language translations. The designer lets you set up translations on a per-locale basis for the app name, each menu item, and even for additional strings in your application. Once enabled the properties files are turned into a series of C++ include header files that...
Embedded Java for Raspberry PI and other embedded Linux
Embedded Java for Raspberry PI and Linux works slightly differently to the C++ project creator in that it is a starter project with a webserver and JavaFX UI built in. After project creation you then go about configuring the project how you like, and the designer will keep the menu callbacks up-to-date in the controller, the menu definitions that make up...
Rendering using themes - properties, grids and icons
Most display plugins can be customized using TcThemeBuilder, a utility class that allows you to simply configure fonts, colors, spacing, grids and icons. To the left you can see cool-blue theme with a multi-column grid layout. Grids allow for multi-column menus by breaking rows up into multiple columns. You can configure graphical settings at the default level, or even override settings...
Setting up IO-expanders in the menu designer
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 objects that refer to either device pins, or any other device such as I2C expanders or shift registers from the IoAbstraction library ....
Integrating EEPROM support into menu applications
IoAbstraction EEPROM support 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 function on menuMgr, and similarly,...
Securing sub-menus and remote connections with an Authenticator
You can secure both sub-menu items and remote connections using an . In summary, when an is present on 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 . In addition, all remote/IoT connections will only be...
SPI and I2C/Wire abstraction that works on Arduino, mbed, PicoSDK
IoAbstraction has core I2C/Wire and SPI functionality provided by several functions, these abstract the use of I2C and SPI over Arduino, mbed, PicoSDK and other supported platforms. Over time the implementation of these will be improved, such that asynchronous behaviour will be possible on certain boards. Prior to 2.0, we had conditional I2C code scattered around the project, but now nearly...
