I was looking into porting much of LH into an Arduino or TI Launch Pad
(msp430) And then a display would be web based.  But then I decided to
go back to grad school and there went any free time.

But I think that is that way to go.  The TB is best kept in some
light-out closet and who wants to stand of a step stool to read an LCD
when a web interface could put a better display on your smart phone or
computer

I did just buy a TI Launchpad.  For $4.30 shipping included I could
not resist but I have in mind a MUCH smaller project

I can't help you with the outboard monitor, but I can help with the haywire / mouse situation.

Windows thinks that the serial port has a mouse connected because of the 1 / second transmissions from the T-Bolt.  At boot time Win looks for serial mice and it gets fooled by seeing something active on that COM port.  There was an answer about this issue from Nov. 1, 2010.

==========================

Easy fix. Add the following to your "Boot.ini" file. Obviously, the "x" stands for the COM port you are using.

NoSerialMice:COMx

This didn't always work for me.  Another way to get it to stop using the mouse is to boot, let it find the "mouse", and then disable it in the Device Manager.  After opening Device Manager you'll find a mouse that doesn't belong there connected to whatever COM port your serial adapter was assigned.  If you move the adapter to a different USB port you'll need to do the process again.

Subject: [time-nuts] Thunderbolt Monitor

I have been following this on the list for a while now and was curious
if anyone is actively working on a open source monitor.  I see the one
made by Adam VK4GHZ is no longer being sold.  This got me back on track
for wanting to make one of my own.

I have been using either tbmon or lady heather but always have issues
with a usb to serial converter when I start the computer.  It will go
haywire and cause it to freeze and make the mouse malfunction.  Once I
disconnect the converter (I have tried other makes as well) it works
fine.  Usually I can reconnect the converter and things will work again.

What I would like to do is make a 2 or 4 line lcd readout to display
various info.  I really liked VK4GHZ's page type selector knob.  I can
see that being very useful.  On a youtube video by n6vmo said the
thunderbolt used a ASCII Hex and "needs to be converted by using 64 bit
floating point math".

So are any of you currently working on this or have decided to quit and
have any information to share?

Hi

Heathdos.exe 123 KB
Heather.exe 572 KB
Server.exe 176 KB

(each would be plus what ever they pull from DLL's and the OS)

Ti LaunchPad MSP-EXP430G2 - MSP 430 version ($4.30):

MSP-430G2553 Microcontroller:

16 KB flash
512 B RAM

MSP-430G2452 Microcontroller:

8 KB flash
256 B RAM

I suspect you would get about 5% of it into a MSP430.

I don't have a way to play with it right now, but in the single-user case, is LH Server.exe equivalent to a simple IP console server?

If so, I think the low-hanging fruit would be to drop an old Lantronix serial port server into the rack, and just use your existing lan/wifi to run the client on your laptop or whatever. No custom anything.

You can't compare the size of a Windows binary to a uP RAM.  If you
look inside the .exe file you see that 90% of it is dealing with the
Windows OS.  The actual computations are very, very small and don't
use even half the 16KB Flash.

Absolutely - however, I suspect the MSP430 might be a little too small.

I'd be looking at something like a Raspberry Pi and a serially
attached screen. Adafruit do some lovely boards like these:
http://www.adafruit.com/products/1115

It's not $5 but it's not exactly exorbitant. Or just use a Pi and a
HDMI capable TV if you have one spare.

Cheers,

Hi

I do believe I included the size of the DOS exe as well as the Windows
version. Both get some support from the OS that you will need to implement
in your code.

It's not just program space either. You only have 512 bytes of RAM on the
larger of the two processors.

You realy can't know if a processor is to large or small until you
have at least a outline of the software design.    In this case the uP
is reading test from a serial port at a low data rate.  It is running
a filter and sending a small amount of text back to the GPS.  So the
load on the CPU is trivial.    The harder part is sending that data
off to a larger computer, likely using Ethernet.  It coud use UDP at
one second per packet.  Depends on how much you want to do on the
device.

That MSP430 is going to be used to interface an anemometer (wind cups)

Mymethod normally is to do as much development as I can on a big
computer like my Mac.  Then move the software down to the target
environment.

TI sells another Launch pad for $18 that uses an ARM.  This is a much
more capable CPU but for data logging maybe over kill.  But if the
plan was to host a web server you'd need something like the ARM.

But actually the AVR inside the Arduino can run a web interface. but
with ARM powered LaunchPads for $18 I'd go with that.

Hi

My original comment was in reply to your suggestion of porting Lady Heather into a MSP430. I took that to be your outline of your project. My reply was simply that Lady Heather is a very complex and full featured program. It does way more than just look at a serial stream and tell you a few simple things.

If the project has now changed into something else, then so be it.
