Hi ,

I would like to use the UART port of my pinapple to interface a Pololu board.

1) is it possible use the UART for other purposes that are not only firmware updates?

2)I have installed pySerial and I made a small program to check the communication to Pulolu board

but I do not understand witch is the right UART:
ttyATH0 or ttyS0.
Here my sample code:
###########################
import serial
import sys
ser = serial.Serial(port = "/dev/ttyATH0 ", baudrate=9600)
ser.open()
if ser.isOpen():
print "Serial is open!"
ser.write("Hello World!")
serial.close()
###########################
I've put a terminal with RX and TX inverted but trought the UART does not seem to transmit anything.....()

Any response or help is greatly appreciated!!!

:rolleyes: :D :D :D

PS.

Plololu use 5V TTL

Pinapple use 3,3V TTL only
