LCD Display using USB

[lomoss7]

Hi

Gathering some info on getting a LCD track display to work using a ft232rl USB to serial board.
Run my code which (works on my other pi) and get this error
import serial
ImportError: No module named 'serial'

How do you import the serial module?

Thanks

Hi Honda

Code is a Python script from Hobbytronics LCD backpack

Code: Select all

import serial
import time
serialport = serial.Serial("/dev/ttyAMA0", 9600, timeout=5)
time.sleep(1)
serialport.write(chr(5)+chr(2)+chr(16)+chr(0xFF))
serialport.write(chr(4)+chr(0xFF))
serialport.write(chr(7)+chr(250)+chr(0xFF))
serialport.write(chr(2)+chr(1)+chr(1)+chr(0xFF))
serialport.write(chr(1)+"Welcome to"+chr(0xFF))
serialport.write(chr(2)+chr(2)+chr(1)+chr(0xFF))
serialport.write(chr(1)+"Raspberry LCD"+chr(0xFF))
count = 0
while 1 :
   serialport.write(chr(2)+chr(1)+chr(13)+chr(0xFF))
   serialport.write(chr(1)+str(count)+chr(0xFF))
   time.sleep(1)
   count = count + 1
serialport.close()

I an trying to do something like the Piface but on USB. Its been 25 years since I wrote any code, so you will have to bare with me.

Thanks

Hi lomoss7,

you need python and pySerial installed on runeaudio.

Code: Select all

pacman -S python2-pyserial

If this does not work take a look here.
