I’m new in this forum and have the following problem:
I 've written a Module K8055N.py with Python V3.7.4 and I am using the original K8055D.dll from VELLEMAN (V22.214.171.124) with ctypes to control the USB-board on Windows 32-bit.
All functions work fine except the following one: ReadBackAnalogOut
and I have no idea on how to use this in Python.
I think, this function has the goal, to receive-back the momentary data from the two PWM’s when reconnecting the board. Am I right?
I 'm a little bit confused about the use of the expression “(*Buffer)” mentioned in the synthax-declaration in the dll-manual:
void ReadBackAnalogOut(int *Buffer);
Can anyone instruct me, how to code this function?
An example in Python3 would be appreciated.
Thanks in advance
