Commands and developing for Espruino

 

 IDE commands

reset();  //most common command when you find problems

after any freeze

require("Storage").eraseAll();

Removes all files, including apps that can't be removed from apps loader 

E.setTimeZone(2);

peek16(0x300c).toString(16);   //TO see the espruino SDK

//0x8C or 0x91 is SDK12

//0x81 or 0x88 is SDK11


Memory usage per app

print(require("Storage").list().map(f=>require("Storage").read(f).length.toString().padStart(7)+" - "+f).sort());

It'll list all files sorted by size and you can see what's taking up the space


Status

process.env; 

process.memory();

require("Storage").getStats();

(total, free,...storage bytes)

E.getBattery() ;

print(require("Storage").list().map(f=>require("Storage").read(f).length.toString().padStart(7)+" - "+f).sort());
