 What I want to show today for the Circa Python Parsec is a really simple command that you can use to check how much memory is being used on your board when you are doing things, when you're importing things, when you're importing libraries, when you're using big files. How much memory have you got left? This is a really simple command you can use. It comes from the garbage collection, garbage collector library. And here's how you can use it in real time. So what I'm going to do is go into the REPL for this Pico that I have sitting right here. And now I'm going to just go and hit control C, which brings me directly to the REPL after going into screen. And I'm going to import GC, which is the garbage collector. Now the garbage collector has a bunch of different things you can do with it. But what I'm going to use is this mem free. So if I do a G, let's say print, print GC mem free, it will tell me I have about 210K. If I then import a library, so I'm going to import another library, let's do import USB HID library, then I can run this print command again or just GC mem free will work. And you'll see now my available memory has decreased because we've added another library in. So as you can see by the code I have up above, you can sprinkle this through some code while you're debugging it and working on it so you can have it do things, maybe bring in a library, check the available memory and use it as a way of figuring out where you're running out of space in case that's something that's happening to you. And so that's how you can use the garbage collector to check the available memory on your board inside of Circuit Python. That is your Circuit Python Parsec.
