CircuitPython: Cranking Up Performance to Eleven #CircuitPython #Python #BadgeLife @NordicTweets @UriShaked
On Medium, Uri Shaked writes about jumping into Badge Life (creating your own DIY electronic conference badge).
Uri chose some bleeding edge technology:
We decided to go with the nRF52840 chip, as it is energy efficient, and support both Bluetooth Mesh and OpenThread mesh. In addition, it runs CircuitPython, which means the attendees will be able to customize their badges by writing Python scripts and saving them to the badge through USB.
The nRF52840 is supported in CircuitPython 4.0.0-alpha, pretty gutsy using code only posted 17 days ago by Adafruit as an alpha release.
After considering several alternatives, we decided to go with a VS1053 chip, as it can decode both MP3 and OGG formats, and stream them directly to headphones.
Uri had some issues with SPI and rolling his own VS1053 driver. Things turn out very well in the end with Uri’s advanced skills (and we may have to grab that VS1053 code to put in the library).
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
