Re: Testing TNC-pi

Use ./pitnc_getparams 0 0 to access /dev/ttyAMA0. I suspect you are running
./pitnc_getparams 1 0.

The normal usage with the latest version is

usage for i2c: pitnc_getparams i2bus i2cdevice
usage for Serial /dev/ttyAMA0: pitnc_getparams 0 0
usage for Serial other device: pitnc_getparams device 0

Using 1-5 for device opens /dev/ttyO1 to /dev/ttyO5. This was added for the
BeagleBone Black version of the TNC.

The latest version can be found at

Ok update:  I got in the mail today another TNC-pi that I ordered for
another project.  I put it together and got it on the pi.  New install of
OS.  I am trying to reconfigure to use i2c.  When I run getparams I get:

Using Serial port /dev/ttyO1
Device /dev/ttyO1
Com Open Failed: No such file or directory

I can seem to get it to use port /dev/ttyAMA0.  Ive been through all the
documentation and I cant figure it out.

How to I get getparams to use /dev/ttyAMA0?
