I'm using the python wrapper of the PicoSDK to use a ps5000a. I'm able to init the device and use it in streaming mode. However, I'm not able to succesfully excecute the ps5000aEnumerateUnits function to list all available serials. It keeps on returning the fault:
Code: Select all
ctypes.ArgumentError: argument 2: : wrong type Code: Select all
import ctypes
from picosdk.ps5000a import ps5000a as ps
count = ctypes.c_int16()
serialLth = ctypes.c_int16(1023)
serials = (ctypes.c_char * serialLth.value)()
ps.ps5000aEnumerateUnits(ctypes.byref(count), ctypes.byref(serials), ctypes.byref(serialLth))Thanks,
Best,
