There are different version numbers for the desktop software and the
firmware that runs on the board.

The firmware hasn't changed through the latest batch of improvements
to the desktop side.

I have a new Handy Board and I am attempting to read an analog input for the
first time.  I have a trivial infinite loop that reads an analog port value and
displays it.

The problem is that each time the analog function is called, the HB beeps and
displays 'Port is in use by Expansion Board'.  The only problem is that I have
no expansion board installed.  The problem occurs only on ports 0 and 1.  The
other ports report values of 252 or 253 with nothing attached to them.

I have reloaded the IC 8 firmware with identical results.

Any ideas?  Are ports 0 and 1 reserved for the expansion board?

Thanks,
Mike

Yes, the default software libraries assume an Expansion Board, and
reserve those two pins for it.

One simple workaround is to use analog(16) to get analog(0), and
analog(17) to get analog(1).

Or, you can track down the library file and change the code.  I think
it's in hb.c.

As I have understood I have to cut the motor power trace and then plug the new
power source into the motor power header. But what happens to the Expansion
Board then? Doesn't the servos and sensors get their power through the motor
power header?

I have noticed that the EB has a power input, could I use this to power the
servos ++? In that case could I split the battery pack going into the HB to also
power the EB?

Or does anyone the right solution?

Hi everyone,

I am refactoring the Handy Board web site, built on top of WordPress.  I hope
that this will encourage people who are still using it to share their work.

The new site's presently live at:

http://handyboard.dreamhosters.com

I'll be switching over the domain name soon.

Please have a look and give me feedback!   Thanks!

Fred

If I were to order extra pins to solder onto wires which could then be inserted
into one of the analog or digital inputs on the HB, what size or gauge should I
order?

Also, can anyone recommend a store which would carry these pins?

Thanks!

DigiKey- Not sure what size though

These are male header pins.  See the HB parts listing for a digikey number:

I went to botball.org and downloaded the Interactive C 8.0.2 program to write
and test my programs for school.

We are required to use "reset_system_time()" in a problem and the simulator
gives me this error:

Cannot load simulator (Are the simulator libraries set in iclib.txt? Do they
compile?)

The program worked well for several little examples that did not contain that
function.

Any thoughts?

Hello Ericson,

I haven't seen any direct code for the Handyboard for
I2C but there may be a couple options.  One site that
has some information and chips to interface I2C is
here:  http://www.i2cchip.com/

Another option may be to offload all the I2C stuff to
another micro controller and just talk serially to
that from the Handyboard.  I'd probably look at the
Propeller chip.  You can get a development board for
low cost, the development tools are free, and there
is already an I2C object written that you can use:

Hi,

This is off the topic a bit, but since I finally see a message from real
people I thought I might ask: can the moderator or list owner PLEASE
delete the user who keeps spamming the list with posts about hot young
virgins &c?

This list seems to be the only one of those I subscribe to that has more
than the occasional such message.

Thanks,
James

I'd be willing to be a backup moderator for the group
if one of the current moderators can enable that on
my account.  I already help moderate a few other
groups and could help with this one too.

I am glad that the spam problem is finally being addressed. I was not sure what
to do about it, but I must admit I was almost ready to leave the group as it
seemed that spam was the only content. Hopefully we will now have some more
interesting (ie. Handyboard) stuff to read!

Yes, but is it being addressed??  I haven't heard or
seen any posts from a Moderator stating that they
would clean it up.  I've offered to help but I
haven't heard back from anyone yet.  I really like
the Handyboard and it is nice to have a group for it
but if the SPAM isn't controlled then it will be time
to leave the group.

I had a series of articles in SERVO last year that
used the Handyboard and also created a modification
to fix the motor startup issue if the firmware is
lost.  It is something that should be done on any
Handyboard being used on a larger robot.

Hello Jamie,

I am studying under Mr. Mar and find the provided code especially relevant to my
project. While I am making an earnest effort to interpret it independently, I am
rather new to this and under a deadline and thus would appreciate if you could
comment on the modifications necessary to work with simply the handyboard and
expansion board. In related issues, while I can clearly see the declaration of
the ports, I'm unsure of which they refer to.

Thanks in advance,

I apologize in advance if this creates duplicates for Jamie, but I misunderstood
the operation of yahoo groups on my initial attempt and know that I, at least,
do not check the email associated with this account.

It makes use of an added output port but that can be modified within the code.

While I appreciate Jamie's contribution, which ports it is referring to and how
one would wire to make the division along input and output rather than SDA and
SCL continues to be beyond me.

What I have made more sense of is the SPI_IC.ic code located in files. Does
anyone have prior success with the use of this code or at least know if the
following recommended scheme simply means that I wire the SDA and a 1.2KOhm
resistor to power on MOSI, and SCL to MISO?
Does that make sense to anyone as achieving I2C?

/* Assumes the following connections: MISO is the CLK (Clock), MOSI is the
    SDA (Data), but these are easily changed:
                               SDA  SCL
         .----.----.----.-----.----.----.----.----.
         | -- | -- | SS*| SCK |MOSI|MISO| TX | RX |  Port D
         `----^----^----^-----^----^----^----^----'
           D7   D6   D5   D4    D3   D2   D1   D0

    The port is operated in wire-or mode so pull-up resistors (~1.2KOhm) will
    be needed on the data line */

Hi Brian,

I am not familiar with the HandyBoard expansion board.
Because the HandyBoard has dedicated input and output ports (not bidirectional),
two ports are required for each signal on the I2C bus.

I used the existing input ports but added a 74HC574 latched octal D-type
flip-flop to the Y0 address line on the HandyBoard to provide an output. The Y0
selects for a read address of 0x4000 in the HandyBoard memory map. I chose
0x4FFF because, well, I don't remember.

So, each of the SDA and SCL lines have a separate in and out line.
The device I was communicating with has circuitry to connect this to a
bidirectional bus. Also, the lines are inverted logic as I had probably run out
of inverters on the target board. This was a long time ago and I no longer use
the HandyBoard for this purpose.

I was looking for the circuit diagrams to forward but have not found them yet.

Hope this helps clear things up a bit.
