Connecting to UF32 with P&E Multilink - joss_scholten2000 - Oct 28 18:24:00 2005
I've been trying to connect to a UF32 board with the P&E micro
Multilink to the boards BDM. The multilink works fine with a C32
board I have, but no dice on the UF32.. any suggestions?

Also, I don't know if this is related or not, but the chip itself on
the evaluation board seems to be extremely hot and gets there very
quickly. I believe the manual indicates this is normal, but I just
wanted to double check.. can anyone else who has used a UF32 confirm
that it gets this hot?

'DP256s do not get hot. How much current are you pulling from your
ports and how are they configured ? (pullup, etc.)

RE: Re: Connecting to UF32 with P&E Multilink - Darren - Oct 31 5:40:00 2005
Check that the internal voltage pins aren't
connected to the chip power supply. This has
been the cause in the past.

Sorry,
Can you clarify what you meant a little, I don't follow.. And this is
still an issue on the development boards? Thanks.

There's an issue with some mask-sets of the UF32 regarding a secured
device-- once they've been secured, they cannot be unsecured. (secured
HCS12 devices do not allow BDM communication).
It sounds like you've inadvertantly secured the device....

Re: Connecting to UF32 with P&E Multilink - joss_scholten2000 - Oct 31 13:14:00 2005
What would lead to it being accidently secured? I just got the board,
although I'm unsure if its been used before (doing some work for a
professor), but I've done nothing except turn it on and attempt to
connect it. Thanks.

Re: Re: Connecting to UF32 with P&E Multilink - Mark L. Cukier - Oct 31 13:19:00 2005
The security byte is simply a flash location... so programming this
location with a given value would secure the device. I would talk to the
professor and find out whether or not he's programmed the device-- if he
has, check out the S-Record to verify whether or not the security byte
(detailed in the UF32 user's guide) was programmed with a "secure" value.

Can your hot chip boil water? Does it fall within the temperature
specs of the product?

6812 to PDA thru usb - Dr Stewart Prince - Oct 31 16:53:00 2005
Does anyone have experience communicating between a PDA (Palm OS) and a
6812 via usb? I've done this using serial communication, but with usb
there's always the issue of one device being a host
I think a good approach might be using the ft232bm, which is an easy fix
for usb to serial conversion, but what about on the PDA side?

RE: 6812 to PDA thru usb - Jonathan Masters - Oct 31 17:05:00 2005
If you can solder it, the CS2102 from Silicon Labs is a better
USB-Serial device from a parts point of view - no external crystal and
only one external R and C needed to make USD-TTL Serial.

RE: 6812 to PDA thru usb - Janet Lefko - Nov 1 10:54:00 2005
I have used both the Silicon Devices UART to USB chip (CP2101) and the
FTDI 2232 and FTDI 232BM in our products interfacing to the USB port on
a PC or PDA. The Virtual Com Port drivers (VCP) configure the host -
in this case , the PDA or PC - to accept the data through the USB port.
If you use the VCP drivers, the data will appear in the serial buffer on
the PC (PDA). Modifying the DLLs will allow you to access data directly
from the USB port buffer.
The USB port is ALWAYS the host or master. Since a PDA is by default a
USB slave, you have to buy a USB Master card. Then the PDA acts as a
Master or Host as a PC. There are some cards, using the USB-on-the-GO
where the PDA can act as a slave to a PC but a Master to your instrument
or peripheral.
We buy a USB Master card for the PDA - HP iPAQ - from RATOC (Japan) or
Twin-Paradox. The RATOC card only sources 100 mA instead of the
specified 500 mA but the company is modifying their card for us to
supply 250 mA which our product requires. Janet Lefko

Janet
Thanks for your prompt reply. I guess the days of a simple $50 pda with
a serial port are gone...I really wanted to use a Z22 to talk to a 6812
using usb. There aren't even any Palm drivers supported by the two
companies listed below.
So, this means I would have to write an interface program for Windows
CE, get a PDA, get a USB Master card, just to do what a simple serial
port used to do? Would a wireless solution be easier?

Re: 6812 to PDA thru usb - Ruben Jönsson - Nov 1 16:52:00 2005
Hi,
The Dell Axim X3 and X5 has an unbuffered serial port. Maby others have to.
When I did some work with these the serial port was somewhat unsupported and
are perhaps gone by now. Or maby not since a lot of PDA's talks to external GPS
receivers via an RS232 port. By unbuffered I mean TTL levels and inverted
compared to real RS232. Just feed it through an RS232 buffer/driver and it can
talk to a PC.

RE: 6812 to PDA thru usb - Janet Lefko - Nov 1 17:23:00 2005
I think the easiest solution is to get a PDA (pocket PC) that will
support a Master USB card. We have a Dell AXIM, ~$200 ?? and the RATOC
Master USB card ~$100. HP / Compaq also sells similar products. The
FTDI website provides the driver DLL and the CE file WindowsCE.net. All
you have to do is insert a call to the DLL in your application. The
driver page shows examples and the tech support, although in the UK, is
knowledgeable and responsibe.
UART to wireless USB is very similar. You have to buy the HW and
interface your data serially to the chip. The chip sends the RF data to
companion HW that's connected to the PC (PDA) USB port. The
manufacturer offers drivers for selected operating systems.
I don't know much about wireless although I did begin to research it
several months ago. I'm not sure if this product will provide a
shortcut.
Here's the link www.eikonsite.it <http://www.eikonsite.it/> PS I
miss serial ports, too.

Thanks for your prompt reply. I guess the days of a simple $50 pda with
a serial port are gone...I really wanted to use a Z22 to talk to a 6812
using usb. There aren't even any Palm drivers supported by the two
companies listed below.
So, this means I would have to write an interface program for Windows
CE, get a PDA, get a USB Master card, just to do what a simple serial
port used to do? Would a wireless solution be easier?

Re: 6812 to PDA thru usb - Jefferson Smith - Nov 1 18:28:00 2005
But why USB? I would find it more appealing to talk through the IrDA
or maybe even bluetooth.
