Hi Thomas,
Well, I recieved my arduino yesterday and started experimenting. I can upload a
scetch to the board and it functions well.
I can also communicate with it via ZTerm. (send and recieve)
Now the most important part: communicating with it via livecode.
Alas this gives me trouble aswell. Here is what I got.
Using Mark's code from the makeboard to get the OSXDeviceNames() and with the
arduino connected I see the following:
(it's important to have the board connected otherwise I don't see those modems)
usbmodem3a21
/dev/tty.usbmodem3a21
/dev/cu.usbmodem3a21
Bluetooth-PDA-Sync
/dev/tty.Bluetooth-PDA-Sync
..... ......
etc.
Further I can open a driver with: open driver "/dev/cu.usbmodem3a21"
and see a result on the board, it's resetting (as in the manual so this is as
should be)
I can also close the driver.
I haven't been able to recieve data from the board, but I am able to send
something to the board.
I send it a 1 and on the board I have a scetch which checks if it recieves
data. If it recieves data,
it will send the same data out with a delay of 500 millis. So when I send data
from livecode
I see the Rx led light and thereafter I see the Tx light, which means the board
did recieve something and sends
the incomming data back out.
Now I am gonna try to figure out what it recieves and what it sends. (Probably
I am gonna hook the whole bit up to a scope
so I can see what's going on on a electrical level)
If I use open file instead of driver it doesn't work. If I use the
/dev/tty.usbmodem3a21 instead of /dev/cu.usbmodem3a21
livecode hangs with the beachball and I have to force quit.
Well that's as far as I got till now.
Perhaps it would be a good idea to discuss/collaborate some of our
effords/failings etc. offlist.
As soon as I have something more I will contact you. Feel free to mail me with
your addional results/questions/suggestions etc.
Best wishes,
Claudi
