This workshop is a continuation of the TI Drivers Project Zero exercise. We will expand on that example by creating a simple PC-side graphical user interface (GUI) that complements our example. If you remember, we created a simple application that continually reads an ADC channel & toggles an LED on or off depending on whether or not our ADC reading exceeds a threshold. To do this, we will use a nifty tool called GUI Composer. GUI Composer is a browser-based utility for creating PC-side graphical interfaces for interacting with your hardware. GUI Composer supports several interfaces today, including Serial/UART, JTAG/XDS, or MQTT (for IoT applications). This training is delivered as part of SimpleLink™ Academy in TI Resource Explorer, a collection of curated training modules developed by TI subject matter experts to help developers get up and running as quickly as possible.
