From the Forums: A web-based tool to generate bitmaps on small OLEDs
Thanks to javl from the the forums for sharing this tool with us! They write:
In some of the display tutorials (such as this one) there is a short how-to on creating bytearrays from monochrome images using the Windows based “LCD Assistant”. I didn’t like having to boot a virtual machine to create images, and also I didn’t like the program itself (got some errors and flakey results).
So I made a simpel web-based converter. It allows you to open a file to convert and apply some simple changes (invert color, stretch to fit canvas, etc). It’s also able to read back a previously generated byte array to display the image.

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.
