USB on the 812A4 - André Ribeiro - Nov 6 7:48:00 2002

Hi everyone, I'm thinking in using USB with my 812A4, instead of the typical RS-232 or
RS-485 interface, but I know very little about USB...
Did anyone implemented this before??
What's the best way to do it??
Is there any cheap IC like the famouse MAX202, ADM202 or 75176 but for
USB??? Thanks for your time,

Best regards,
André Ribeiro

RE: USB on the 812A4 - Andrew Bailie - Nov 6 8:33:00 2002

Have a look at the FT8U245AM from FTDI. Its a USB UART, so you pass in the
raw data via an eight bit bus, it parcels it up in all the USB info and
sends it out and vice versa. I haven't used this device but it does look
like the boy.

I will be using the PDIUSBD11 from Philips or the AK4170 from AKM
semiconductor. I havent tried them yet!

Check Cypress. They have quite a family of USB chips in various flavors,
some of which ought to talk to an HC12 fairly cleanly.

I used USBN9603 USB specs 1.1 from National with the Adapt812 from
Techart. The hardware is easy to implement, wrote a small test to
software to communicate to the PC. Took a couple days to implement
so in my opinion, maybe use USBN9603.

RE: USB on the 812A4 - Jim Bacon - Nov 6 10:17:00 2002

Cypress works great -- you can use nonstandard bauds that match those you
can get with the HC12 (62.5K).
The Cypress solution doesn't look like a "virtual serial port", though --
so you might have to get a VID/PID from USB.org.

I'd use the FTDI part if I wanted a "virtual serial port", or a Cypress if
I needed additional I/O capability and/or a unique Plug & Play solution.
I've tried both approaches successfully for internal use.

Could you tell wich part from Cypress you have used.
We are looking to use part for Cypress, and experiences are always welcome.

Thanks for any info

Ronald:

There is a 908JB8 part from motorola (has application ckt, etc)
on their web site if you want to keep all mot code. I "think"
they have a 2.0 part out, but the spec's looked odd when I read them.

They have some others, But you'll need nda to get info. See your local rep.

Re: USB on the 812A4 - Jim Bacon - Nov 6 15:15:00 2002

CY7C64613 series -- I actually used the 80-pin version (CY7C64613-80NC),
which is now unavailable, but the 128 and 52 pin versions are easy to
get. If you need DMA features, this one has some "undocumented features"
(things that don't work) --- consult the tech department before proceeding
with this mask set. CY7C64613-128NC will be the part I use for the next design. It is the chip
Cypress provides with the development board, and does not seem to have any
issues with 'special features'.

CY7C64603 series seems to be a 'subset' of the above parts, and I don't
know exactly what is incompatible -- the tech department basically told me
you can use the '13 to replace the '03, but not the other way around.

Feel free to e-mail me off-line if you want more details.

Re: USB on the 812A4 - Steve Letkeman - Nov 6 17:15:00 2002

As much as I like to use the HC12 for anything and everything,
I did use the AN2131 for my USB product because of its built in
USB capabilities and the fact that it has the great feature of being
RAM based with the firmware stored in the PC. When you plug in your
finished USB device the firmware is downloaded across USB
and then your device fires up. Very cool and great for changing
firmware and emailing the new file to your customers.

(long live the HC12!)

Re: USB on the 812A4 - Steve Letkeman - Nov 6 17:38:00 2002

You can program the AN2131 firmware into an 8 pin serial memory
and when it powers up it loads the firmware from this memory
instead of going to the PC. The biggest disadvantage with this
is that you are limited to a little under 8K program space with
no way of increasing it. If you download from the PC you can
do more than 8K but that's another issue. I know this isn't
relevant to Jim's project but I thought I'd throw that in for any
body else reading this.
Jim's second point needs to be considered also. USB appears
to be simple from the outside but it hides a fair bit of complexity.
Don't underestimate the learning curve of USB. Having said
that, some of the other devices mentioned would likely simplify
the process.

Subject: Re: [68HC12] USB on the 812A4 We looked at that, too -- has some distinct advantages.
Our big problem was that we needed to "guarantee" that the USB device came
up "smart" when power was applied, which meant the code had to be 'local',
because there was no guarantee that the USB would be plugged into a PC on
power-up. If this hadn't been an issue, we would have used that approach.

The only complaint I have about the various and sundry USB choices are that
in addition to the HC12 code, you also have to know/learn/maintain other
architectures. That did get a little messy trying to debug everything....

Re: USB on the 812A4 - Francois - Nov 6 17:57:00 2002

Hi,

Just wana add my 2 cents. The A4 is nice for having a relative glueless
setup with buss type peripherals like these - however migrating to the S12
series does not provide this luxery of tying things to the I/O buss. Is
there any IIC of SPI type USB devices available?

Re: USB on the 812A4 - MTG - Nov 6 23:55:00 2002

The Philips D11 is I2C. I have used it with an 8051 and the
D11 is a nightmare to learn (datasheet is total crap), BUT
there are a few nice examples on various websites that
help out immensely. Check out the forum at www.usb.org.

Most of the USB chip vendors have lots of sample code/projects
to help the beginner out, ... which is a nice thing because it takes
a bit of work to get USB going.

The other PITA is that it now costs $$$ to get a vendor ID from
the USB org.
