Hi,
my new project is to communicate about an RS232 port with an Ergometer from Kettler (like an Velosimulators <-- don’t know if this the right word) to Blender’s BGE to simulate some routs for training.
and this Project called “Ergotours”
first I setup some serial python scripts:
that is an modified version from the official py_serial documentation
import serial
#Can be Downloaded from this Link
#https://pypi.python.org/pypi/pyserial
#Function to Initialize the Serial Port
class Ergometer_Com:
def __init__(self):
COMNUM = 3 #Enter Your COM Port Number Here.
self.ser = 0 #Must be declared in Each Function
self.ser = serial.Serial()
self.ser.baudrate = 9600
self.ser.stopbits = serial.STOPBITS_ONE
self.ser.bytesize = serial.EIGHTBITS
self.ser.port = COMNUM - 1 #COM Port Name Start from 0
#ser.port = '/dev/ttyUSB0' #If Using Linux
#Specify the TimeOut in seconds, so that SerialPort
#Doesn't hangs
self.ser.timeout = 10
self.ser.open() #Opens SerialPort
# print port open or closed
if self.ser.isOpen():
print('Open: ' + self.ser.portstr)
self.loop()
#Function Ends Here
#Call the Serial Initilization Function, Main Program Starts from here
#init_serial()
def loop(self):
readin = ''
while self.ser.isOpen():
'''if not 'ACK' in readin or not 'RUN' in readin:
#temp = input('Type what you want to send, hit enter:
')
self.ser.write(b'CM
') #Writes to the SerialPort
print(self.ser.write) #Writes to the SerialPort
loopstate = 1'''
#else:
self.ser.write(b'ST
') #Writes to the SerialPort
print(self.ser.write) #Writes to the SerialPort
loopstate = 1
while loopstate == 1:
bytes = self.ser.readline() #Read from Serial Port
readin = str(bytes)
print(readin) #Print What is Read from Port
loopstate = 0
ergometer_com = Ergometer_Com()
def main():
ergometer_com.loop()
that is the final version
