IrDA transceiver - linktek - Jan 22 14:48:00 2003

Hi All,
Does anyone know if the HCS12 has IrDA capabillities in the works??. I am looking for a all inclusive solution for my IrDA interface with my HC12. I dont seem to find a device that integrate at least the frontend(wave form shaper) with the pin diodes. Ideally I would have liked a blob with the IrDA stack, wave form shaper and the pin diodes all integrated in a nice small package.....8<))

I was looking at MircoChip IrDA stuff but have not made up my mind yet.

The thing is that I would like to interface my Palm Zire21 (no serial ports) with only IrDA with my industrial equipment. I chose this device because it will be cheap for my customers to buy.

Any suggestions from our experts

Thanks

Frank [Non-text portions of this message have been removed]

Hi,

Yes I noticed, this is a trick to get pass a demo program that
expired.................... changing back and forth - I sometimes forget
8<))

Thanks

Since I have no experience in that field I had a quick look around to get some idea what you are designing, learn a bit:-)

It seems you need something like the HSDL-1000 to perform the hardware functions you want, correct?

Don't know if you are stuck with a bit bunger or can use the serial functions from there.

Keep us posted.

microchip 2150 hooked to the serial port seems easy, right?

Some of us who make a living by selling programs might use a different word
than "trick".

If you use the program, please pay for it. It will encourage the author to
continue supporting and enhancing it.

Re: IrDA transceiver - linktek - Jan 22 23:10:00 2004

Hi,

I guess yer right - go ahead sue me. The reason for doing it was unfortunate
down loaded the demo.......installed it - got side tracked with something
else and when I finally got back to the demo - it was expired and a tease
popped up saying "TIME TO BUY!!!". Well, what was I supposed to do???

This is not exactly Kazaa paranoia - is it? I take it you were just teasing.

Any case back to the real topic, what can you tell me about IrDA solutions
for the HC12?

IrDA or 2.4GHz??? - Bruce McMillan - Jan 23 3:32:00 2004

We have a S12 application interfaced to a CS8130 to do infrared serial
comms. Includes firmware upgrades over IR. It's a nice if expensive
chip. Very flexible.

We are now migrating to 2.4GHz, with the newer chips no more difficult
nor expensive to work with than infrared, and of course "pointing" is
a thing of the past.

An axample are some chips from Nordic.... single chip, no licencing,
pcb track as antenna. Since Nordic don't have a discussion forum, I
have started one...
http://groups.yahoo.com/group/NordicRF/

There may have been a suggestion that M are coming out with packaged
RF too - but I have no direct knowledge on this.

Re: IrDA or 2.4GHz??? - linktek - Jan 23 3:52:00 2004

Hi,

Well thanks man.... for the entusiastic response. So does Palm handheld come
(standard) with 2.4GHz currently AS WE SPEAK??
My angle is from a simple Palm device. Since the designers for the Palm Zire
in their wizdom dropped RS232 (long live RS!!!)
for USB, the only other standard comms protocol is IrDA at this point - for
a cheap .....cheap device.

Yep, I know there is other Palm devices that would support RS232 wired,
however they are much more expensive.

Thanks

Try the MAX3100. It supports IrDA timing "out of the box" for a
simple LED + photodiode application , but with two added inverters,
it will also work with ready-made IrDA transceivers. We used
to use the HSDL-1001 for one application, but it was discontinued
some time ago. There are many other types made by e.g. Agilent and
Vishay, and many others.

Re: IrDA or 2.4GHz??? - Bruce McMillan - Jan 23 4:23:00 2004

The choices at 2.4GHz mirror the choices at infrared. You can have an
IrDA stack, or use an IrDA chip at the physical layer only. Similarly
with 2.4GHz, you can have a Bluetooth stack, or use a Bluetooth chip
at the physical layer only (Nordic).

The stack allows interoperability at high cost, whilst using devices
as physical layer devices constrains interoperability, but is much
cheaper (and generally faster) to develop - assumimg that you have
control of both ends of the link.

I guess you can't get a driver for a USB-serial adaptor cable -
n'est-ce pas?

..call up or email the supplier, explain your situation and ask for an
extension.

ON TOPIC: Pirating - Richard F. Man - Jan 26 1:03:00 2004

People who steal will steal no matter what. They are thieves and nothing
more. Where is the moderator of this group? In theory, can Motorola be
potentially liable if crack codes and whatnots are passed around on this
mailing list?
