sending integer as raw byte #11

Closed JBSchueler closed 5 years ago

JBSchueler commented 5 years ago

This is not a driver issue but I am unable to find the right answer.

outputStr = bytearray([123, 32, 12, 1, 245])

for h in outputStr:
   sp.write( h )

this gives an error...

outputStr = bytearray([123, 32, 12, 1, 245])

for h in outputStr:
   sp.write( sp.write( (format(h, "c")) ) )

Now I get a TypeError

Traceback (most recent call last):
  File "ftwrite.py", line 79, in <module>
    sp.write( (format(h, "c")) )
  File "C:\Users\bsc\AppData\Local\Programs\Python\Python37\lib\site-packages\ft232\d2xx.py", line 339, in write
    buf = c.create_string_buffer(s)
  File "C:\Users\bsc\AppData\Local\Programs\Python\Python37\lib\ctypes\__init__.py", line 63, in create_string_buffer
    raise TypeError(init)
TypeError: ª

So I tried

outputStr = bytearray([123, 32, 12, 1, 245])

for h in outputStr:
   sp.write( chr(h).encode('utf-8') )

Now I am able to print but for none-ascii chars I get 2 bytes

Can someone help me to just send raw bytes?

Uhm... problem solved...

sp.write( bytes(outputStr) )
