I have a RaspberryPi connected to a micromite. It can also connect to Maximites but don't try to supply power to the Maximite via the USB - you are doomed to fail.
The USB ports are restricted to 100mA each

I have it set up as a serial to TCPIP device using 'ser2net'

If you want to see the Towers of Hanoi running, connect TeraTerm to
118.208.247.208 port 3002

If the program is not running type 'run'
Provided no one has done something undesirable, things should work.
TeraTerm should be set to send character at a time rather than line at a time.

It is a dynamic IP so is likely to change ocasionally and I won't leave it running too long.

I have connected no problems.

So, you're using a Pi as a network module, essentially?

Any reason you would not use a cheaper network module, or are you just playing around cos you can, and wanted to see if you could make it work?

The Pi can do (and will be doing) a lot more than serial to net.
It doesn't cost much more than a dedicated serial to TCPIP module.
It can also log connections which is handy for debug work and security.

I intend to run it as a web server with realtime data from the micromite.

All I have to do now is learn Python....

It's a pity that I won't be able to run MMEdit on the Pi.

A model B+ Pi from Element14 is $36au plus GST including freight.
They need a microSD card and draw about 300mA at 5V. They also take a long time to boot up compared to the micromite.

Neat. I was thinking of doing something similar. From your description you connected the Pi via USB to serial and then to the uMite. Did you have any problems with the Pi recognising the USB to serial adapter.

Thanks,
Tony

At this stage, I have the mite connected through a USB-TTL adapter. I think most adapters will work without any driver issues.
Eventually, I will use the one available RS232 on the Pi connected to com1 for a 'user interface' saving the console port for control access.
The only problems I had was when I tried to connect the maximite to the USB port. The power drain was too much for the Pi but it all worked as it should when I powered the maximite direct from the 5V pins.

Thanks to Bert for his Towers of Hanoi game. The timing was perfect.

I have it running and it only took about half an hour. I used one of those cheap Prolific USB to serial converters and the PI recognised it straight away and loaded the correct driver. Then it was only a matter of looking up 'ser2net' on the net.
I used the instructions in the first link I found, set the baud rate to 38400 in the config file with no other changes and bingo I can now talk remotely to the uMite.

Definitely one of the easiest things I have tried lately and could be very useful. Thanks very much for the post.
