[gentoo-user] using gnupic

[maxim wexler]

Hello group,

Like to learn from others their experiences using
gnupic tools. 

What is the best programmer? DIY preferred. Serial or
parallel. What sorts of pitfalls, tradeoffs? Are some
of the pic chips more linux-worthy than others?

I plan to use a K6 500MHz AMD as a dedicated pic
development platform. Any tips on how to configure it
for best results? USE flags etc?

Mostly use windoz based tools for Microchip embedded firmware
development. I'll install this and look at the support
for the 18F series. But I have access to many pic dev
boards for testing.

MPlab ICD2 driven off of usb. Jtag is always the best device
for low level hardware debugging.

This a joke? Pics do not have MMU, nor any sort of significant
memory resources. I do not know of any uClinux hacks using
uClinux on a pic, although you could if one wanted to,
I suppose.......

Um, you must have missed architecture class when minimalistic
risk processors were  covered. The K6 is a 'CISC' 
architecture, compatible with x86 architectures, the last
time I look....

Any tips on how to configure it for best results? USE flags etc?

You might ask here:

I'd be curious to follow you acheivements in getting pic, as
in a Microchip 18F processor to run a mimimal linux kernel/rtos.

A very good rumor has it Microchips 24F series of micro controllers
will be accompanies by an embedded linux port, of some sort.

If you really, really are serious about pic developemnt using an
IDE, then read this article where the author outlines how to
hack support, via a cross compiler into Eclipse, for a particular
microcontroller:

"Developing Eclipse Plugins" in the March '06 issue of The LinuxJournal.com
Article by Mike McCollough.

I do sort of follow these sort of issues with keen interest.....

Well at the moment it's a little difficult to download:

emerge -v pikdev
<snip>

!!! Couldn't download pikdev-0.7.1.tar.gz. Aborting.

Look like the package is not available  even though it
is marked stable......

???

Just so you know, I am not a programmer. I do have to use PIC's in
various project and each time I have to suffer through hacking existing
code to make things work. To program the PICs I use ponyprog. There is a
linux binary version available and is quite easy to setup. You can use
parallel or serial port.  A while back I read that a linux
version/work-alike for mplab was in the works, I never followed up on
its progress.

Cheers.

Only if you think I meant to put a linux kernel on a
pic chip.

I'm just starting out. As a first project I'd like to
generate an audio sine wave at say, 1kHz.
