e-paper GDE021A1 display

i thought to be clear about the attached javascript in the first post, it is not a proper module, just an example which one can use to start, right now i am working on a code version which is more in line with a real module coding-style

For the sake of brevity - it looks like there are quite a few
constants that are not used!

i started with porting the complete SSD1606 diver specification, which provides a lot more than just displaying some values

You could also shorten - COMMAND_xx to say C_xxx.

for a proper module i thought of using

/**
 * ...doc for each command
 */
SSD1606.prototype.C = {
  cmd: new Uint8Array([
                      0x01,
                      0x02 // ... and so on
                      ]);
};

is that ok?

as a newbie i am not aware of e.g.

Best thing is to make GDE021A1.prototype.C into just var C

i started with http://www.espruino.com/Writing+Modules and will - when it's functional - apply http://www.espruino.com/Performance

Are there more places to get hints on best practices for programming Espruino?
