AVR-Chat

Hi all

I am into building RoV's and use the "robotrov" Yahoo group.
I am going to get into this microcontroller using a avr chip.

What I would like to know is what's out there for me. Yes I have
browsed the web but I need a starting point I.E. the chip. software
I need to control 6 servos or esc's
4 switches on/off
3 sensors depth . temperature. light.

A purpose built control panel with another Avr chip inside.
or if I got 2 a laptop and a joystick to control from topside via RS 
232.

I live in the U.K.
there is a store below that looks OK.
http://www.active-robots.com/
I currently use a radio control to control but I gota get into
something that is programmable and upgradeable.
Any input would be most welcome.

Regards Antony(UK)

There are several very good resources on the internet. One
is AVRFreaks.org Another is AVRbeginners.net.

For development tools, I tested many, but best ones
are:

CodeVision AVR Compiler.
-- use this compiler if you want to test something or
even just write a program to do something simple. It
is not a good for best performance or good
programmers.

GNU C/C++ Compiler or GCC.
-- This is the best I found. you can download from 

www.sourceforge.net
looking for WinAVR project.

but this is a command line compiler which is hard to
use. you can download AVRStudio 4.12 with SP2 from
atmel site. install GCC, then install AVR studio.
you can write programs very simple and easy.

To program AVR micros, use ponyprog2000 or AVReal
1.25.

ponyprog is a general perpose serial programmer and
has a GUI, but in some cases, the AVReal (which is a
command line tool) is more faster and better than the
others. specially when you want to clock the micro by
PC in programming time.

for some helper sources, google for avrlib.

good luck;

I zapped the fuses on the AT90USB1287 that comes with the STK525 and 
now the Flip bootloader doesn't work. I tried obvious combinations of 
fuse setting after reprogramming with "bl_usb.a90", but I can't get 
Flip to load code into the AVR. Flip tells me "Device protection is 
set"! - All is not lost, I can still ISP program the board, but I'd 
like to know what the fuses should be set to.

Anyone with an STK525, can they tell me what fuses are set on the 1287?

Peter.

You are SO privileged just to have a 1287!! I can't even
get price and availability for a 1286 (or a 646) for over
a weekso I had to revert to the good old FTDI chip and an AVR.

Hmm, then I won't tell you I also have five (5) MAX3421E samples then!

Talk to Archna at Soanar. Maybe she pulled some strings for me?

But seriously, if you want just device mode USB, and still want to 
stay with Atmel, then the ARM7 chips look quite good. I'll be very 
happy when ARM7 gets USB host-mode (have to go to ARM9 for that, and 
then that's using external flash, and expensive!). ARM7 is now very 
cheap ...

   http://www.atmel.com/dyn/products/product_card.asp?part_id=3521

BTW, I'm looking at using the 1287 in host mode, and the MAX3421E, as 
an SPI peripheral, does this. But they both suffer from real-world 
supply problems. And, as far as host-mode USB mass-storage class 
drivers go, they both suffer from a lack of example code. Atmel in 
France (Jean-Christophe) assure me however that they will release code 
(NDA) this June.  Parts mentioned can be found here ..

For an application that needs 5 i/o and about 500 bytes of
flash (written in assembler 50K in C)? :-D The clients unfortunately
wants USB connectivity, so I thought I'd be smart and use the USB646
(not available yet) so I went for the USB1287 which is SUPPOSEDLY
available NOW, still no reply as far as price and availability and
cannot even found on O/S web sites like Avnet etc.. so it's back to
the good old tiny2313 and ftdi232r which gives me almost a component
free application as the clock is internally generated and all USB
components are built in, I will only need a few 100nF caps.

I think FTDI would have sold more of these devices if they had made 
available a DIP package. Either the 232 or the 245 are, and will 
remain, very good quick solutions. But, if absolute reliability is not 
too much of an issue, you can do a USB device with just the 2313 - see 
AVR309. The firmware needs a very small mod to assemble under studio 
4.12 and there's a working version for the Mega-8 in the zip file too. 
I tried it the other day and the demo source code assembled and works 
a treat, even comes with a Win32 Application. But remember there's 
little error checking and it relies on a noise free environment, so 
it's a hobby-solution rather than a real-world solution ...

has anyone tried using this particular programmer:

with ATmega16 or ATmega32?

Has anyone had a problem with an ATMEL JTAGICE MKII that will not enter the
isp programming mode.

I also have the early model ATMEL JTAGICE that enters isp and programs fuses
/ lock bits OK using the same board and connector as the MkII has the
problem with.

I am using Studio 4.12  SP2  Build472.

Thanking You,
Owen.

Yes; I've got one. Works fine. However, make sure that it programs all 
the devices you want to program; I had to get an AVR JTAG mkII to 
program some of the newer devices (especially the ATTiny25/45/85).

Thanks Ned for the heads up :-)

Doesn't just interface to AVR studio, so long as this has the chips are
in the studio would this not work?

I have studio version 4.12 - is this the version you have?

Will email olimex to see what they say as I want to order one soon.

I don't generally use AVR Studio, as I don't generally use Windows.
However, the interface to the Olimex unit is the same as the JTAG 1 from 
Atmel, and it will work with both AVR Studio, AVRDude, and avarice.

Any chips that are supported by the Atmel JTAG I will be supported by 
the Olimex unit; look at the help file for the JTAG I in AVR studio.
