 So for today's circuit Python parsec, what I wanted to show is a little tip on finding out some info about your board from the REPL or from the serial interface to your microcontroller. So I've got a Feather RP2040. It's plugged in over USB to this computer. And inside of Moo you can open up this serial window. So this is now a direct connection, a REPL. I can type things in directly on that board. So first thing I'm going to do is I'm going to import OS. So I've imported that library of operating system like things. So what I wanted to do is find out what board I have plugged in. And you might ask, why do you want to do that? I've got it sitting right here. Well, actually have multiple boards plugged in. In fact, I'm not even sure which one is going to show up. I have my little camera switcher over there. That's the circuit Python board. And I have this Feather. So let's see what comes up. If I type in, I'm going to print os.uname.machine. So this is a Feather RP2040. And I can also check which version of the operating system is on there, which version of circuit Python in this case. So if I do print os.uname version, it's going to tell me I'm running 6.2.0 release candidate. And that was the version I downloaded on the first of April. We might also want to know what pins do I have at my disposal. For example, that QT PyRP2040 has two I squared C channels on it. You might not know that looking at it. So if I import board, I've now imported the library for board pin definitions, I can now just simply type in board dot and I'll hit tab for tab completion. And now I get a list of all the pins that are on this board. So I can see this one has a 0 through 3d, 0, 1, 10, 11, and so on. I squared C is on here. I have a neopixel on board. We have the serial RXTX, SPI. So kind of an interesting way to find out info on your board without even having to go to a web page as long as you remember these, these little commands. So that is your circuit python, parsic.
