Espruino Memory Viewer

This tool allows you to connect to an Espruino/Bangle.js device via Web Bluetooth and then display the contents of RAM as a Network.

It's a good way to look into your code and see if there's anything obviously using memory that shouldn't be.

To use it:

• Open this link

• Click Connect

• Wait...

• Then click and drag and use the mousewheel to zoom

• Clicking on a node will show you information about that node at the top, including a calculated path which may be able to show you where the variable is defined.

• RED are global and hidden objects in Espruino

• GREEN are functions

• GREY links are added between array/object elements to enforce ordering

After initially connecting, you might want to do something on your device that is causing memory usage to increase, and then click the Diff button. This will scan all memory again and will make all variables that were previously allocated grey (note that if variables have moved around, it is possible that new variables will be turned grey instead).
