Tried to run the basic example from your blog post, on virtualenv:
import serial
import time
from tools.ccTalk import *
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=1)
def send_message(header, data='', source=1, destination=2):
req = ccTalkMessage(header=header, payload=data, source=source,
destination=destination)
req.setPayload(header, data)
ser.write(req)
data = ser.read(50)
messages = parseMessages(data)
for message in messages:
print message
init = ccTalkMessage()
init.setPayload(254)
ok = False
# Wait for device to be initiated
while ok != True:
ser.write(init)
data = ser.read(50)
try:
messages = parseMessages(data)
response = messages[-1]
print response
except:
continue
if response.payload.header == 0:
ok = True
else:
print response.payload.header
# Set inhibit status to allow all
send_message(231, '\xff\xff')
#Set master inhibit status to enable device
send_message(228, '\x01')
#Read buffered credit or error codes
event = 0
while True:
try:
request = ccTalkMessage()
request.setPayload(229)
ser.write(request.__str__())
data = ser.read(50)
messages = parseMessages(data)
for message in messages:
if message.payload.header == 0:
data = message.payload.data
if ord(data[0]) > event:
event = ord(data[0])
print "Counter : " + str(ord(data[0]))
print "Credit 1 : " + str(ord(data[1])),
print "Error 1 : " + str(ord(data[2]))
print "Credit 2 : " + str(ord(data[3])),
print "Error 2 : " + str(ord(data[4]))
print "Credit 3 : " + str(ord(data[5])),
print "Error 3 : " + str(ord(data[6]))
print "Credit 4 : " + str(ord(data[7])),
print "Error 4 : " + str(ord(data[8]))
print "Credit 5 : " + str(ord(data[9])),
print "Error 5 : " + str(ord(data[10]))
time.sleep(0.2)
except KeyboardInterrupt, e:
print "Quitting..."
break
ser.close()And that's the error:
Traceback (most recent call last):

Any ideas?
Can't Dispense Coins From Hopper
I've a coin hopper and I'm trying to dispense coins. But I'm always getting NAK response for the 167 Header.
Normally, all the ccTalk documents I've found says: Get the serial number with 242 header and add number of coins to dispense as hex. Concatenate them and send them as data with 167 header.
My test program:
import serial
from tools.ccTalk import *
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=0.2)
def sendMessage(header, data='', source=1, destination=3):
request = ccTalkMessage(header=header, payload=data, source=source, destination=destination)
print " -> " + str(request)
ser.write(request.raw())
data = ser.read(50)
messages = parseMessages(data)[1]
print " <- " + str(messages[1])
print("Data: %s\n" % messages[1].payload.data)
return messages[1]
print "[*] Pinging device..."
ok = False
# Wait for device to be initiated
while not ok:
try:
response = sendMessage(254)
except:
continue
if response.payload.header == 0:
ok = True
else:
print response.payload.header
print "[*] Request manufacturer id ..."
sendMessage(246)
print "[*] Request product code"
sendMessage(244)
print "[*] Enable hopper"
sendMessage(164)
print "[*] Getting serial number"
sr = sendMessage(242).payload.data
print "[*] Dispensing coins..."
sendMessage(167, sr + '\x01')And my output is:
