L01 Memory

[Eric24]

Does anything need to be done to "enabled" the extended RAM on the L01 with firmware v1.8.0.b1? Or am I not going about measuring it properly?

I get the following response to micropython.mem_info():

stack: 768 out of 7168
GC: total: 67008, used: 8896, free: 58112
 No. of 1-blocks: 43, 2-blocks: 10, max blk sz: 384, max free sz: 3541

What exactly is this telling me? What is the "units" of the items on the GC line?

@eric24 You have to use the recent firmware. The extended RAM is supported from 1.10.0.b1 on.

@eric24 That's the heap memory ... GC means kind of garbage collected.
There's a total of 67k of heap memory and almost 9k are used.
The heap memory in Python - this is like the RAM that your program might use dynamically.
