Hero999 · 18th June 2007, 10:37 PM

I've just finished building the PIC programmer on Nigel's site.
http://www.lpilsley.co.uk/pdf/p16pro40.pdf

Here are some pictures of the PCBs.

I've put it into a box; I'll post some pictures of that when I get round to it.

All I need now is some software to use with this.

I'd prefer it if it's for Linux or will at least run under WINE as I am slowly moving away from Windows and I would also prefer it if it's open source. I've checked out Nigel's site but it all appears to be Winwoes only although I will check to see if some of it will run under WINE.

Then I'll set about building an LED flasher.

I also have a project planned for a PIC, it's a bathroom extractor fan timer. The idea is you pull the switch once and it turns the fan on for 10 miniute, pull it twice and it stays on continuously and pull it again to turn it off. I did origionally design it using a 555, a dual flip flip IC and a quad NAND IC but now I've finally decided to get into PICs I've decided to abandon that approach.

What PIC should I start with?

I want something with a built in oscillator, a minimum of two IO pins (one for the switch and one for the output) and that comes in a small DIL package with minimal pins.

Check the PICList, there is a small amount of Linux stuff out there!.

3v0 · 19th June 2007, 12:01 PM

For the bathroom fan check out
PIC12F609-I/P 8 pin 1.75KB Flash 64B RAM 6 I/O 8MHz internal oscillator

For general learning I like the PIC16F88

8-Bit Microcontroller IC
7K bytes Flash
8 MHz Int Oscillator
Number of I/O Pins:16
Clock Speed:20MHz
Package/Case:18-DIP
EEPROM:256

I makes a LOT more sense to specify program memory in words, because that's how it's used (and the only way it can be used).

So the 12F609 has 1K words of memory, and the 16F88 has 4K words.

Hero999 · 19th June 2007, 02:46 PM

Thanks for the replies.

Wow there is a lot of choice, I suppose as there are no special requirements for my application then would I be wise just buying the cheapest PIC possible?

I can't find the thread be I remember Nigel suggesting a PIC in place of a 555 awhile ago and I can't remember which one he suggested.

Any 8 pin one would do, the 12F609 mentioned above would be fine.

I'm not very sure about this, but I've faced this problem among my friends and I myself: The hardware and software have to be synchronized, i.e. not all the programming software support all type of programmers. Let's talk about parallel port programmer, some uses an inverter and some uses a buffer as the logic. So the programming software are different. But I'm not sure whether there is any way to make them to be universal. It is because some programming software doesn't support some new PICs.

Best to know both. Both have value.
Machines with larger instructions GENERALY require fewer instructions.

Data is stored in bytes.

No big deal. Why are you giving me guff ?

The ONLY reason is as an advertising ploy, to make it appear larger than it is!, there's no value in splitting the words into bits and reassembling them in bytes.

Not in PIC program memory it's not!.

No guff, just making the point - it makes much more sense to specify the size of the memory as you use it.

Hero999 · 19th June 2007, 07:09 PM

So I take it that all PIC instructions are the same size on a specific device?

I've done some assembler programming on both an x86 PC and a microcontroller (can't remember what type) and different instructions required different amounts of memory.

On the low and mid range devices they are, for example the 16F series use all 14 bit words, and all instructions are just one word in length - so the 14 bit word can contain an eight bit data 'byte' and a six bit instruction (such as RETLW 0xFF - the RETLW is the first 6 bits, and the 255 the next 8).

The 18F series etc. have a small number of double word instructions.

Gayan Soyza · 20th June 2007, 05:41 AM

I think for Hero999 its better start from windows & assembly language until you get descent knowledge in PIC programming Due to several reasons.

*Easy to understand

*More resources software’s (IC Prog, WinPicprog / Serial Port Emulators etc……)

*More supported programming hardware’s

*More debugging tools (simulators)

*Plenty tutorials (microchip application notes)

*More supported forum friends

After that you can shift to any other OS or Higher Level Language or 18F series.

All the best

Hero999 · 21st June 2007, 10:06 PM

I don't mind sticking with some Windows software for now but if I do then I still want the option of being able to take all my code and move to another piece of software on the the Linux platform without modifying it. I don't want to get locked into using a certain piece of proprietary software that I only origianlly intended on using temporally.

By the way, here's the completed article.

Now all I need to do is buy some PICs to program.

Hi Hero999, the chassis looked nice
