Issue 22 HackSpace magazine: Graphical output for (almost) any board #Displays #Microcontrollers #CircuitPython #Arduino @HackSpaceMag @ben_everard
The new HackSpace Magazine Issue 22 highlights being able to connect ubiquitous SPI digital displays to microcontrollers using CircuitPython or Arduino to program the interface.
Sometimes you need a little bit of graphics or text output for your projects and, for this, TFTs are a great solution – they’re cheap, available in a range of sizes, and well supported by maker hardware.
The main thing you need to know when looking to get one is the driver chip it uses. There are a few that are easy to use; in this tutorial, we’ll look at ones driven by the ILI9341 chip. The driver should come on the TFT board, so we don’t need to worry about wiring the two together. Instead, we just need to connect the module to our microcontroller.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
