hi everybody
i've got a serialport connection capable arduino.
i saw a couple instructions on net about how to connect arduino to maemo devices with usb host capability.

for example here:
http://blog.locationist.net/2008/03/...o-interaction/

in that project they used a usb connection capable arduino.
today im going to buy a serialport to usb converter which contains a driver cd

but probably the driver in that cd wont be for maemo.

so.. main point is that can i use module files in linked page above instead of that cd contains.

i hope i could explain what i wanted to say.
sorry for my english

Hi there. You might be fortunate and maemo will already have a serial driver for usb enabled though this is unlikely. I imagine the drivers listed on the link you provided should work as essentially the usb on the board will have a usb to serial adapter. If it doesn't work you should be able to enable such a driver through configuring the kernel.

i just bought the converter

next goal: a maemo controlled robot

Thanks to Fanoush: http://talk.maemo.org/showpost.php?p=101312&postcount=5 Just insmod them in. I found the FTDI drivers more stable. Works great with screen, gpspipe, etc.

i got a problem about installing pyserial module
it always giving same error.
when i try to run this command:
cd /media/mmc2/ps
and then
python setup.py install

and it says
no module named distutils.core

please please help

i fixed distutils.core problem but...
there is still no available ports except /dev/ttyS0 which always exists.
i runned scan.py which scans available ports
but there is no port called ttyUSB0

please help

when i run dmesg command:
it is printing lots of lines that says
EAC MODE :
play enabled , rec enabled
playdisabled , rec enabled
play enabled , rec enabled
lots of these lines
also it keeps sayin usb-auto suspend
and hub_suspend

im trying with pl2303.ko module now
------------------
i think my usbserial converter is pl2303 due to info. above that i found in its driver file
but still not working with pl2303.ko module file
there is nothing abt ttyusb0 in dmesg

Here sorry I missed earlier but this will take care of the USB to serial modules for all linux compatible devices on Maemo:

I've used this before and serial devices always show up properly. I think ftdi (?) chips are the most common for microcontrollers like arduino, the pl2303's tend to be more for the stand alone USB-serial adapters... but that's just been my experience, don't know for sure!

Assuming your USB to serial adapter is plugged into your NIT with the proper adapters, using the file I linked to above, try this:


insmod /path/to/your/mods/drivers/usb/serial/usbserial.ko
insmod /path/to/your/mods/drivers/usb/serial/pl2303.ko

Assuming you've already apg-get install screen
(you may need to install nano first if I remember right)

To get a 9600 baud terminal type

screen /dev/ttyUSB0 -FTCYPKJ5 9600,cs8,-ixon,-ixon,-istrip


If you have gpspipe installed and want to get 4800 baud NMEA GPS sentences out of your 810 type

gpspipe -rs /dev/ttyUSB0

More about gpspipe here http://talk.maemo.org/showpost.php?p=278271&postcount=7

What does this deb do? sticks the .ko files somewhere and automatically insmods them on bootup or something?
