Setting up the Software Tool Chain For the software you need a C-compiler to compile your programs into machine code and a bootloader to download and ‘burn’ the machine code into the microcontroller’s internal Flash memory.

This can cause annoying lags when NoICE catasheet memory to refresh the screen.

Project Owner Contributor FlashProg: That said, this is pretty forgiving and easy to get to work, unlike some of the analog transistor stuff I attempted and failed with 30 years ago. To install it download the source code from hereunpack and save into a directory named ‘bl08’ in your home directory. What I want is something that can be whacked together in matter of hours or a few days on a prototyping board.

Into the ‘Project name’ entry field enter a name for the project, call it ‘hello’. Before we can issue the download command we need to find out what is the name of your serial port. If you are designing a board, this is a very handy feature to include. It is your project and your life. Among the files produced there should be one named ‘blink. The original Dartmouth BASIC born in like me was a very simple language that contained all the basic building blocks that you need in a programming language, but lacked the basic higher level abstraction features that I think are essential, like named subroutines, local variables and parameter passing, and structural control statements, without which programming is rather similar to assembler programming, making it difficult to manage anything complex successfully.

Corrections and revisions of my opinions are encouraged. Besides doing it from the ground up just is the way I do things!

Our first program will just blink a LED. Looking for a microcontroller For years I’ve been looking for a suitable microcontroller that would fulfil my self-imposed constraints.

Datasheeg you get something like -bash: BTW There is logic according to which Freescale name their parts. Some HC08 variants cannot use Block Erase on their interrupt vectors.

This is used by the breakpoint logic: However, be aware that a standard PC serial port can only generate baud rates that are exact divisors ofBASIC has a special place in my heart, it ratasheet the first language I learned and it still has certain appeal in its simplicity and ease of learning. So create the following ‘Makefile’note the Capitalization, in the ‘hello’ directory: The chip will enter MON08 mode even if the entire Flash is blank. The manual should also tell you the name of the port but you can datawheet find it out yourself.

A lot of people vaguely cite that they want to learn to ‘do microcontrollers’ or ‘learn datashset new programming language’. Since I’ve not used it I cannot say what it takes to program it in-circuit as I want to do, but surfing the web you see a lot of options software-wise.

Must use Mass Erase, as Block Erase cannot erase the vectors.

For serious professional work the Silicon Labs chip seem to provide best bang for buck in terms of being the industry standard core with minimal external circuitry, fast clock speeds and more than adequate memory sizes. However, if you intend to use the board mostly for debugging with NoICE, this modification can save you a lot of annoyance.

This is not snobism, it is just that I expect the pros to have done their homework when selecting their tools and chips. Exact requirements may be found in the datasheet for your processor. MON08 relies on sending a bit serial break at various times. It just makes sense. So it takes even longer, and before you know it your enthusiasm is gone and the project just becomes one of those ‘I’ll finish it one day” -projects.

To permit full access to Flash on the Nitrons, you must connect an external 9. The available processor configurations are stored in files with an extension of “. This is also the way professional bring up datasheeet boards, just do something simple like blinking a LED to see that the system is at least alive — you can’t run until you can walk, so you need to take baby steps first.

If you are a complete novice to the command line I suggest you read my Linux for Dummies which covers the basics.
