Open Source LittlevGL GUI Library on Adafruit Touch LCDs #Adafruit @McuOnEclipse

Running graphical user interfaces (GUIs) on microcontroller boards is a tough thing to do. On the MCU on Eclipse blog, they post a project integrating a NXP LPC55S69-EVK and adding an Adafruit display with either a capacitive or resistive touch interface.

Software and Hardware used

An example project with all the files is available on GitHub. The software is configured to use the capacitive or resistive touch display. I recommend using the capacitive touch version, as the touch is much more accurate and there is no need for manual calibration.

Wiring to Feater LCD
The board can be used with the Adafruit Feather LCD board too

The Adafruit ILI9341 based touch displays are a great and easy way to extend a board like the NXP LPC55S69 with a state-of-the art open source GUI library. The project presented here supports both the capacitive and resistive touch displays from Adafruit.

See the blog post for the full details and references.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
