the picoscope does not work #162
Description
Does not open picoscope
Good day . I'm trying to connect with an oscilloscope, for example, with this example:
"""
Shows a demo of use to use the enumerate devices feature.
By: Mark Harfouche
"""
from __future__ import division
import picoscope
import imp
picoscope = imp.reload(picoscope)
from picoscope import ps3000a
ps3000a = imp.reload(ps3000a)
import time
if __name__ == "__main__":
SERIAL_NUM = 'AT635/230'
ps = ps3000a.PS3000a(SERIAL_NUM)
#ps = ps3000a.PS3000a( )
allSerialNumbers = ps.enumerateUnits()
print("Found the following device serial numbers: ")
for serial in allSerialNumbers:
print(serial + "\n")
# you can open devices by serial number
serial = allSerialNumbers[0]
ps = ps3000a.PS3000a(serial)
# do stuff
ps.flashLed(10)
time.sleep(4.0) # the above flash takes roughly 4 seconds
ps.close()
And getting an error:
E:\ChipWhisperer5_64\WPy64-3740\python-3.7.4.amd64\lib\ctypes\__init__.py in create_string_buffer(init, size)
61 buf = buftype()
62 return buf
---> 63 raise TypeError(init)
64
65 def c_buffer(init, size=None):
TypeError: AT635/230
Using SERIAL_NUM = "AT635 / 230\x00"
It produces the same error as described above.
When you try to set data in a picoscope without using a serial number, an error such as a picoscope is not detected. This has already been considered in the comments in this thread.
What could be the problem ?
