They are all the same, only different, that is the problem. But hey, lots of people use BASIC or some improved C-like language to program microcontrollers, surely that makes sense?

That’s when I really get frustrated.

The Bootload Adapter The bootload adapter converts the voltage levels of your serial port to match those required by the microcontroller and allows you to download software into the microcontroller as well as provides a handy way to debug and experiment with your system.

Thus, datasheer can continue to start up in monitor mode even without Vtst applied to the IRQ pin.

Having fun with HC08

Those were the days. Some HC08 variants cannot use Block Erase on their interrupt vectors.

With this schizophrenic mind set I cannot help bringing some of my professional baggage to my spare time activities although the motivations, goals, requirements and resources of professionals and hobbyist differ considerably. Which sort of proves my point about requiring something datashheet can 68ch08 whacked together in one weekend and has a future!

Now you can go through your whole development cycle of editing, compiling, linking, downloading, programming and executing by with a single key press.


On the panel that lists all the commands scroll until you find ‘Run Last External Tool’ command and select it. If it can’t be programmed in C it is a non starter.

It can be done in a home workshop – I’ve done it myself, but I’ve also been forced to outsource some SMD soldering on one of my hobby boards! Lacking this, NoICE will prompt you when to cycle power 668hc08 your target. I guess this is the long term view again: I know, it limits your options, it is more work, it makes no sense, but its great fun. The Microcontroller The microcontroller I’ve used is pretty much datashset.

It is useful, but not necessary, that NoICE be able to automatically perform this reset. I’ll bet you anything that the guys writing Unix code more than fourty years ago had no idea that a lot of this code would still be running and tooted as the most advanced operating system available today: Before moving on, it might make sense to briefly consider what we have just done.

Merely reading them may cause some special action and it is not always possible to read ‘back’ what you just wrote into a register, some registers are read only, sometimes the same address accesses different hardware depending on weather you read or write. For anything larger 68hcc08 a single file test program I highly recommend using make to automate the process.

This concepts also applies to input and reading of peripherals. It has a large user space and is available for all major platforms and support many languages. We are going to fire up the Terminal to get access to the command line but before we do that we do a litle tweak that will lessen the amount of typing we need to do.


From the short list that will appear select 68h0c8. Your home directory is the folder with your username inside the ‘Users’ folder.

I’m mainly repeating the information here for my own reference, there is nothing special about this setup, datasheeg if you are new to this the notes may help you get going, after all the datasheet is almost pages long, with a half a dozen application notes thrown in! I secretly suspect that the major reason for their success is that they offer so many of their devices in plastic DIL packages!

If you need a fast burner for another family member, please contact us. Note that the User Monitor takes over the interrupt vectors. Peeking at internal RAM is useful as application debugger too.

Mac OS X supports make out of the box so there is nothing to install, and so do most Linux distros, in Cygwin you need to install the C-development tools but I won’t be covering that here.

A lot of things are poorly executed, as if the developers themselves never used them for real work.
