Hi Al,

you can watch your postings with a newsreader:
Newsserver: news.gmane.org
Newsgroup: gmane.comp.hardware.texas-instruments.msp430.gcc.user

It's also very comfortable to search older news.

Thanks Florian. I think I've pinned it down to an errant son, who,
despite many denials that he was logging in on my account, was caught
red-handed. I wondered why traffic had been slow. Every time he logged
on he was downloading my mail, and deleting it!

That's One son banned from on-line gaming for a week. The ultimate

The TI datasheets says "the LFXT1 oscillator in LF mode requires a
watch crystal".

Is there something specific about a "watch crystal" other than the
32.768khz frequency that is required?

I need to use high pressure tolerant crystals in my design. They come
in 32.768khz. Can I use this instead of a watch crystal?

Bob,

AFAIK - the 'thing' about the watch XTAL is the parallel capacitance. 'watch
xtals' have a specific requirement that is met by the MSP430. But you can add
extra caps to match the required value of your xtal.

Your spec sheet should give required value, and the MSP430 has some already, so
you only need to add the difference.

Hi !    what is a high pressure tolerant Xtal? As I know it the tuning fork
xtal shall work in a vacuum, or , to say it better, the fork motional
resistance does increase a lot if the fork is forced to work in a
non-vacuum environment.
Motional resistance can be too high for the quartz to operate properly, or
for the microprocessor to drive the x-tal.
If there is a high pressure outside of the can this is a potential higher
risk. The watch Xtal is manufactured in a metal can with glass feedthrough,
for this reason, there are a few ceramic cased ones, they are much costlier
and do exhibit a higher motional resistance.
The MSP430 is optimized for low power Xtal drive, it may not be able to
drive a high motional resistance xtal.
However I am not aware of this specification (max motional resistance)
being given in the MSP430 datasheet.
They normally do think that saying that it shall be a "watch Xtal" does say
all.
So have a look to all of the specs in your high pressure Xtal.
And, anyhow, since I do not know what a "high pressure tolerant crystal" is
, my doubts may be of no concern at all to you.
Finally, if possible, let me have a reference to this kind of Xtal, I am
curious!
Regards
Antonio

printer interface is straight forward.

Minimum it require 10 I/O pins, 8 data, 2 for strobe
and busy check.

strobe:output
busy: input

Procedure:

1. Set strobe high. This is the normal condition.
2. Make sure printer is not busy (normally high is
busy, with some printer (24 column) it is reverse.
3. out the data
4. give a low going pulse (100uS to 1ms). Set low,
wait, set high.

Refer manual for special commands (esc sequences)

Antonio,

I am designing an instrument that goes in an Autonomous Underwater
Vehicle. The housing is filled with oil and operates at ambient ocean
pressure. The vehicle needs to operate down to 1000 feet so the parts
used have to be able to withstand high pressure. Many crystals,
capacitors and other components shatter or don't work at that
pressure. Since high pressure operation is not usually specified in
component datasheets, we hvae to do our own pressure testing on
components to see what will work.

Got the idea!
Have you already tested any "watch" Xtal or any quartz crystal at all ?
As far as I know these components are among the few remaining that are
housed in a metal vacuum case.
Most other common parts are solid resin filled.
So an outside pressure of approx. 30 Bar may not be the best situation for
these parts.
If you are obliged to do your own testing I suggest you test the xtal for
motional resistance degradation as well as for the other known parameters.
Hope this is a good hint, or tell me if I need to clarify my saying.
Regards
Antonio

I was there (in Dallas). I would expect more announcements from TI in
the end-of-Q1/Q2 2005 timeframe ... The MSP430 is very nicely suited
to Zigbee due to its low power consumption and fast wake-up, so TI has
a possible winner on their hands with this combo.

jkw_ee
Send Email Send Email
 
I was wondering if anyone else had run into issues with the hardware
I2C on the F1611. I am using USART0 as both I2C and a UART, I have
implemented this with sucess talking to a PC and a TMP100 temp
sensor. This have been operating for a while. Today I attempted to
bring the DS1339 RTC on line on the same I2C bus but it sure does
not like me. I think the difference between the TMP100 and the
DS1339 is that I am doing writes rather than straight reads. I run
the same piece of code and sometimes it works sometimes it does not.
I have verified my SCL timing to make sure that I am not overrunning
the devices. I have seen the SCL timing do some strange things.

The problem is now that my TMP100 is pouched to. Has anyone else had
difficulties with the I2C? I hope someone else can shed somelight on
this before I go to a S/W I2C to see if it operates better.

Thanks

abz_msp
Send Email Send Email
 
HI all

In my code I swap the baud rate on my UART dependant on what sensor I
am sampling.  Usually from 38400 to 9600 and then reset it once
sampled.  The different sensors are connected to various drivers and
then routed through an addressable mux to UART1.  The logic is then
TTL but the baud rates match the sensor.

However, I have noted that the UART sometimes hangs between changes
meaning I cannot get data in.  If I swap to a 485 sensor and then back
to the 232 it usually corrects itself.

Something "odd" seems to be happening at the UART.

Anyone else experienced this or have any thoughts??

cheers

To be sure that the Uart works reliable you have to set the SWRST Flag
before you do any changes in the UART registers. At the end you reset
this flag (and reinitialize the uart state machine).

As far as I can tell, the hardware I2C is screwed on the 1611.  Most
people here resorted to bit-bashing as the F1611 is just plain crap at
driving it, and it locks up (in my case).  I know I'm doing it right,
I've got pukka code from TI, it just doesn't work.  Best consider the
F1611 broken in this respect.

Regards,

Hi,

If you've decided to use the standard section names, import the
memory_map.xml file and alter the place where CODE starts.

Further searching turned up airbee wireless.

http://www.airbeewireless.com/airbee-zdk.php

Looks interesting but I would much prefer the greater range offered by using the
915MHz band :(

Still, I would love to hear how the MSP implementation seems to work if anybody
ever decides to use (or has used) it.

There's actually a small place on the South Australian coast called
hope. But it's sure not close to Adelaide. It's funny, I couldn't even
begin to count the number of placers I'd lived, if only for short
periods, I've spent 24 hours or more (a visit must be more than a day)
in 122 countries and lived in (spent more than a month) 14 different
places in Germany, more than 20 in England, a dozen in Australia, around
10 in Singapore, a few in Libya, several in saudi, 4 in bahrain, and
various in other middle eastern countries, as well as a ragbag of
different european places. Of all of these I prefer Adelaide by quite a
long way. It's quiet, but within reach of anything I need, it's coastal,
has decent weather, great thunderstorms, people that still talk to each
other unarmed,  affordable housing.

Hello Blueman,

You may not be able to use crystals at all. Even if a few tested ok
the next batch might still become crushed. I have seen at an
underwater vehicle manufacturer how stuff looks when pressure is applied.

I am not sure how resonators behave here, maybe worth checking out.
Else you might want to look at mil spec parts. These come with much
more detailed environmental specifications than civilian part. At a
price, of course.

Another idea if its a tethered vehicle: Can you extract one of the
signals coming down, such as video H-sync and lock on that? Or maybe
send a master clock down via muxing it onto one of the cables?

If not, maybe you could pot that crystal into a can that is strong enough.

Regards,

Joerg.

The 169 doesn't behave like this, I2C seems to work ok modulo the known
problems (IIRC).  And yes, I do have source code, but I'm not sure it'll
help you, it's for my compiler.

Yep! We first lived in the Pas Aris Hotel, a secure compound for
military families only, right on the beach, with a jetty. I was just 4.
We watched the flying fish leaping out of the water 20 yards away. This
was in 1957, during the Indonesian insurgenicies. the night before a bus
loaded with families had been ambushed and wiped out. The first mornign
we woke up my two brothers and I went tiger hunting. We were there
around 5 weeks waiting for a house so we could re-unite with our father.
We then moved tempoaraily to a place in Serangoon, 5 weeks, can't
remember the street. next was a skip across Serangoon to 32 Borthwick
Drive. On a hill, right side as you descended. here while scavenging
unexploded fireworks ater some festival we forgot to put the brake on my
baby sisters pram. She rolled down the hill, hit a rock, flew out into
the stream where she was well and truly green slimed. My mother didn't
believe our excuse. We were there about 6 months, then RAF tengah, for 6
weeks into temporary accomodation, 3 months at Tengah, then a promotion
saw my father posted to Changi. 6 month spell at Changi, where we had a
friendly rivalry with the local chinese kids. To get them to come play
we'd shoot the pots and pans hanging on the walls outside their Kampong
house with catapults. Their mother would send them to chase us off, and
we'd all clear off to the beach for the day. I remember a family called
the Quinns who we were very friendly with as well. Next was a month in a
Singapore city hotel again while we transferred, and my father was at
Butterworth. Next a private rental along the 'mad mile'  a stretch of
road with a steep drop off and a vehicle graveyard at the bottom.I can't
remember the exact name of the place jalan something or other. The sight
of several local buses (piaLebur?) at the bottom didn't endear you to
local transport.  Finally to 8 Mornington Crescent in Seletar, where we
spent 2 years or so. The house still stands, although I believe the two
pines, one either side of the entry gate, are no longer there, and the
'cringer' tree in the back garden has probably gone (cringers are large
vicious red ants). us three boys slept on the balcony there (it had
shutters, but no glass windows I recall). There I had some of the best
times of my life, and made many interesting 'scientific' discoveries.
So, I was wrong, only 9 different places ;@}.

So are TI implementing the Zigbee on a special '430 or is most of the
'fruit' in an external interface device?

I had a lot of problems with I2C and F1611 also, and since I needed 2
hi-speed SPI and one lo-speed I2C, I decided to emulate the I2C interface
with software, with no more problems.
The datasheet wasn't clear to me, the sample programs from Texas
Instruments worked fine, but wasn't exactly what I needed and any changes I
tried to make resulted in instabilities or wrong operations.
