Fine. I have saved the xwisp.py file as attached in the private mail. Thanks ! The 18F1320 now programs and my quick-port from the F628 actualy works !! Just a note, when browsing through the new xwisp.py file, I saw this line : # 07-FEB-2003 v 1.07 # baudrate switching changed for Wisp628 >= 1.08 =============== My Wisp628 says this when starated : "hardware: Wisp628 1.03 (fast)" ============ Now, are these versions the same thing ? The web page says : "19-NOV-2002 1.03" as the latest firmware. Wouter van Ooijen wrote: >> Is XWisp/Wisp628 supporting the PIC18F1x20 ? > > The XWisp version on my website does not.
