Love those ST Cortex M? processors. The pin selection utility in Cube is
awesome but it would be nice if they added the source and sink
capability of each part to it. The Nucleo boards are so cheap that they
can be used in a variety of projects.

It's even worse than that. Some of them have programmable drive strengths,
so it depends on the software you are using as well as which pin you are
using.

When you say a 100 uA pullup, is this *really* a current source or a FET
wired as a resistor or really a resistor? When does it draw/source the

just make the input high impedance or use a lower current pullup?

This is an already existing chip... designed (by me) for another
purpose... natch; but now the customer wants to use it for another
purpose in spite of it is not really a match :-(

I don't get the problem. Give him a spec on your input and either let
them deal with the interface, or you can design an interface circuit
once you see the data sheet on the DAC output.

Where is the problem?

BTW, is your input digital? If not, why do you have a "current source"
on it? No, forget I asked that one. I don't really want to know.

It's an analog input with a precise 100uA current source pull-up to
allow the user to simply add a resistor to ground to set a threshold
value for an internal comparator. Now they want to force it with an
external voltage source. I'm gathering that uP DAC outputs are
weenie??


Ok, now we know the rest of the story. I can't say how "weenie" the DAC
on an unspecified chip might be. I have no idea how you can draw any
conclusions. Why can't you just let the customer drive the signal
knowing the requirements?

There are such specs on every processor and FPGA I've seen.

And they are all different. Even one single processor often has separate
specs for various (groups of) pins.

Sure, this whole discussion depends on what is meant by "general
specifications". Yes, each device has its "general specifications".
Of course they're going to vary across manufacturers but I assumed JT
would know that not every pin in existence would be identical. Perhaps
I thought too much of his abilities. ;-)

Now, now! I don't use uP's, so I have to rely on what my customers
tell me they're going to do to my chips. When they tell me
nonsensical things I try to sort them out here.

Does every single chip you've ever designed have exactly the same I/O
parameters? Why should uC I/Os be any different? Get the spec and
read it.

Every end user will have a different uP.


Without some constraints, no answer to your question is possible.

I have since squeezed from _my_ customer that it will actually be a

moot.


Do you know what its drive capability is? You better find out, or at
least specify the limits.

ok sir u guys had wrote the coding using BF981 but i dont know were we can use this netlist coding if the solution their means is their library files are present in that same tool for example if this coding is used in HSpice or PSpice is their library file available and i have another doubt is why the transistor model is not available in LT spice or any Spice list.

I have the same problem, when I try to sim welding smps.

dit all things but it do not work, except when remove the opamps from the feedback, sometimes it do start, but most not.

I have file but do not now where to post.

Hello,

I've built a small CNC machine that should, in theory, be able to mill a
blank copper clad card to create a two sided PCB. I'm moving into the
testing stage and would like to get more serious about the software.

Has anybody done this before (hobby niveau)? If so, what kind of
workflow did you use?

In particular:
- Is there a particular PCB CAD application that outputs the appropriate
type of file ("negative" HPGL for example)?
- I gather "positive" HPGL files must be cleaned up to account for the
cutting tool size and cleaning out large areas of copper. Are there any
good applications or shareware out there? Projects?
- Any hardware issues (does a special 60,000 RPM motor really help???)

Any pointers would be appreciated.

Regards,

Hi all,

I came across this (http://groups.google.com/groups?q=g:thl3097468609d&dq=&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=7fkval%24abg%241%40denws02..mw.mediaone.net)
posting from David Krofchok (krofchok_at_mediaone.net) dated 999/04/21.

I wanted to know if anyone has any info on what David was talking
about when he talked about reconsidering "screen printing etch-resist
ink onto a copper-clad " board." I know that screen printing etch
resistant ink on copper-clad boards was (is?) an industrial strength
process around 15 years ago (Have seen it happening myself when I was
a kid) .

Can anyone point me out the method of doing this and the advantages/
disadvantages of this method over photetching.

The problem with photoetching seems to be that the photoresist coated
board tends to be expensive. I have also not been able to find it very
easily in Bangalore, but I guess RS components stocks them but as to
the price I have no idea :(

Could anyone give me any pointers, please?

regards,
sachin
