st7565-designer is a HTML5 web application for designing bitmaps and fonts for the st7565 graphical lcd. Encoded bitmaps and fonts work well with Adafruit’s ST7565 arduino library. This web application was written for my own use and was designed to run locally on my own computer. I tested it with recent releases of Firefox, Safari, and Chrome. I did not test it in IE, nor do I intend to do so.
Draw a line between the last pixel and the current pixel by holding down the shift key.
Undo with ctrl-z or command-z. No redo yet.
Save and restore bitmaps/fonts from local storage
Export/Import all items to/from a JSON file
Drag and drop an image on the canvas (with canvas dimensions set to 128×64) to write a dithered approximation of the image to the display
Current quantization/dithering techniques available: Floyd-Steinberg, Atkinson, and Sierra Lite (Sierra-2-4A), and Threshold
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
