I have a project that uses a 16F876A with a 4.0MHz crystal. The project is mounted on a PCB of my design that incorporates a serial port using a MAX232. When first using this board which I programmed with a borrowed ICSP programmer and MPLAB 7.01 I was able to get the system to do the traditional "blink the LED" and then to echo back characters sent to it from a terminal program on my PC. So far, so good. I no longer have access to the programmer and have build a Wisp628. I used Bumblebee (BB) to drive the '628 and things went south in a hurry. Neither of my test programs work when they are programmed with the BB/628. Probing around with my o'scope showed that the system had no clock running. This leads me to believe that the CONFIG options are not being set correctly with BB. I can upload the "fuses" from the PIC with BB and when I scroll through them I do not see the value 3F7A that I expected to find (LVP_OFF, WDT_OFF and HS_OSC). BB reports all the fuses as 3FFF. The PIC seems to get programmed. What am I doing wrong? Any BB users out there? I have downloaded XWisp and Python and got set up to use XWisp. I can run XWisp at the command prompt and get the list of command line options. However, I can not understand how to proceed. I need a short tutorial. Is there any documentation for the command line options? There does not appear to be any at www.voti.nl Any enlightenment will be appreciated.
