Some context

I have a accelerometer/gyro/compass (Minimu9 v3) connected to my RPi by i2c.

It is working fine, and the minimu9-ahrs software pipes the data perfectly to a visualizer (ahrs-visualizer) using the following terminal command :

~$ minimu9-ahrs | ahrs-visualizer

I am trying a similar command to send the same data to the serial device ttyAMA0

~$ minimu9-ahrs > ttyAMA0

when executed, the cursor drops to the next line and waits (does this mean it is sending?)

I can see the serial device in PD, and it appears to be open:

"[comport] opened serial line device 0 (/dev/ttyAMA0)
port_list: 0 /dev/ttyAMA0"

BUT - I am getting no data,

would anyone know if I am on the right track?

ps. I have reached this stage with alot of trial and error, and literally no idea what im doing ( it has taken about a week - since i got my Pi and also started learning PD!)

@druffdan it is worth saying that i had disable ttyAMA0 in the startup file (cant remember which now) to "free it up" and that worked.

I am now looking into dev/pts/0 but that is also not churning any numbers through
