Good stuff here. Thanks! I'd just like to add a little bit. For those who don't know pascal, please see the python script pasted below. This can be used to test your dll. This specific example is for 3xinput and 2xoutput:

from ctypes import *

# first make some hooks into the impported functions
initiateController = cdll.controller._initiateController
getControllerOutput = cdll.controller._getControllerOutput
performCleanup = cdll.controller._performCleanup

# This makes python realise that the function outputs are pointers to c_chars
initiateController.restype = c_char_p
getControllerOutput.restype = c_char_p
performCleanup.restype = c_char_p

print "\n\nInitiate"
errMsg = initiateController()
print "initiateController reports : ", errMsg

print "\n\nNow to do some stuff"
inputDoubles = 3*c_double
inputData = inputDoubles(2.5, 3.0, 1.0)
p_inputData = pointer(inputData)

outputDoubles = 2*c_double
outputData = outputDoubles(0.0, 0.0)
p_outputData = pointer(outputData)

#The following line shows two different methods for passing the pointers in
errMsg = getControllerOutput(c_int(3), p_inputData, c_int(2), byref(outputData) )
print "getControllerOutput reports : ", errMsg
print "output[0] = ", outputData[0], "\noutput[1] = ", outputData[1]

print "\n\nCleanup"
errMsg = performCleanup()
print "performCleanup reports : ", errMsg

Hi, I'm looking for a programme to create an 2D FDTD.

Could you help me, please?

The tutorial helped a lot.

Thanks.
