Re: [Flashforth-devel] Baud rate

[Mikael N. <mik...@fl...>]

$c4 constant ubrr0
: 250k #3 ubrr0 ! ;
: 38.4k #25 ubrr0 ! ;
: 9.6k #103 ubbr0 ! ;

' 38.4k to turnkey
warm

Note that in order to disable any faulty turnkey word you need to have a 
usable UART connection during the first 2 seconds of the restart.
I order to disable the turnkey you need to start the terminal program 
with 9600 baud and press the escape before the turnkey word executes.

I will change the next FF arduino hex images to use 38.4K as default.

Probably Python is complaining about the missing pyserial library.

Google install pyserial.

On linux I start it with
cd ff
sudo shell/ff-shell.py --xonxoff -s9600 -p /dev/ttyACM0
