Your first test

OK, so you set up the software, MPLAB-X. Run it. Takes a short time to load up. Now, let's make a project. You don't need any hardware yet, just your PC. From the menu, select File, then New Project. Click Next. Type in the device as shown here, PIC16F15345. Click Next. Click on Simulator.  Click Next. You probably won't have many, if any, of these. So click on Download Latest and follow any instructions. A compiler is a piece of software which takes what you write (this will be code in the C language) and compiles it into what the microprocessor understands (this is code in assembler language). We can look at this later. Once it's finished, you can select the XC8 Compiler and click Finish.  Now fill in the boxes like this (replace YourName with whatever you log in as). Click Finish. You'll see a couple of panes like this:   OK? Now you've made a project. It won't do anything yet, because you haven't told it what...

MICROMEISTER!

Hi everyone! I say everyone, it's probably nobody at all, yet. I'm a microprocessor engineer. I've recently tried finding another one to replace me, because I've been doing this too long. I've found loads who say they are, but they're not. So, here am I, offering to teach anyone who's interested how to get involved with this INCREDIBLY TECHNICAL AND CLEVER STUFF ! Dear reader - it isn't. Really it isn't. It's very, very simple. The people who make the chips and the software we use are the clever ones. They make it easy for us ordinary people to use them. To be honest, the hardest bit is thinking of something to do with them. If you're interested in this sort of stuff, you will have heard of things like Arduino and Raspberry Pi and such like. "Make your own computer," they say. No, you won't. You'll buy theirs, and there will be strange experiments to do, using strange languages, and you won't have MADE anything. ...

What happened?

This is where you'll see the difference between playing with a little plastic chip and playing with the Web, Windows, Unix, MAC and all those other huge toys. Remember the end bit of this ? How, and why, did it jump out of the loop and start again at the beginning? A "normal" program wouldn't. But most microprocessors have a thing called a watchdog. It's a friendly thing. Here is one: The watchdog keeps an eye on what your code is doing. We'l go more into it later, but the reason the code jumps back to the beginning is because of him. You can turn him off. Put him back in his kennel. Let's do that. In the Window Menu, underTarget Memory Views, click on Configuration bits. Look down the bottom, you'll see them. There's one there called WDTE. You can find it. Click where it says ON and turn it to OFF. Now debug the program again, and see if it runs ad infinitum . That's Latin. Impressed? Bet it does. Hope it does. I...
