Please report any bugs or suggestions in the development forum: Version 0.1.6 (1 Oct 2023) -Added Sparkle Matrix Block -Added Sparkle Baton Block Version 0.1.4 (7 May 2023) -Optimisations to the Crumble compiler means (typically) more than double the amount of code will fit in the Crumble. -Updated VM to latest -Added support for Smart Crumbs -Added new servo block for 270 degree servos -Several bug fixes and minor improvements Version 0.0.22 (2 March 2022) -Small tweaks Version 0.0.21 (14 Feb 2021) -Added file saving and opening -Added ability to print -Added additional USB error checking to prevent Crumble lockups -Improved touch control -Optimised block rendering to increase graphics performance -Other minor bugs fixes Version 0.0.14 (10th July 2019) -Added additional data verification during programming to prevent corrupting Crumble firmware (only appears to occur on certain models of Chromebook). Version 0.0.13 (24th Feb 2019) -Added realtime variable monitoring -Improved USB communications Version 0.0.12 (19th Feb 2019) includes all blocks except custom named variable blocks. The following limitations also apply: -File opening/saving is not yet available -Realtime monitoring of variable is not yet implemented -Undelete and duplicate are not yet implemented -The software will run offline, but you will need an internet connection to send a program to the Crumble (compilation is currently done in the cloud). The Crumble is a cheap, easy-to-use electronics controller. A few ‘croc’ leads and a USB cable are all you need to connect motors, LEDs and sensors and begin experimenting. No programming experience is required as the free software is a graphical, drag-and-drop system inspired by MIT Scratch.

*Nearly* usable as a substitute for the Windows vn. Lack of File Load/Save is the only function I can identify as a showstopper, in the school I am converting from using Windows laptops to Chromebooks.

Works well. But is missing some of the features of the PC version. In particular the right click "duplicate" function. And also the ability to be able to use any name for a variable. No doubt Joseph is working on this....
