Re: Programming with connected I/O
Hi Ben, Thank you for the response. Appologies for getting my Vdd/Vss crossed. What ever happened to Vcc and Gnd? But I still have the situation; Pin 1 = clean 5Vdc Pin 8 has spikes of varying magnitude but up to 1.6V at what appears to be 20 mS apart which seems to point to the 50Hz supply. The 14V...

Re: Programming with connected I/O
Hi, I am still having difficulties. Pin 8 (Vdd) wrt power supply gnd shows random spikes upto 1.6 V o-p (I have a Picoscope Image but unable to attach picture) Vss is a clean 5V dc. Not sure what is going on but I dont think it would be overly healthy. Where does Vdd originate? Obviously it is not t...

Re: Programming with connected I/O
Thanks for the response Ben. The system is set to HS with the crystal selected and the watchdog is off. Is there an explaination for this - I went back to check settings and repowered the board and the program started running - It was not running when I switch power off. Then I attempted to load the...

Programming with connected I/O
Hi This is a general question – Is it recommended to remove the connected I/O devices before programming/reprogramming a PIC using the HP488v3? I seem to have damaged two 12F675 by what appears to be reprogramming with I/O connected -making simple timing changes. I ran a small test flashing LED prog...

Re: USB cable not connected
Hi Ben, thanks for the suggestion but this was done previously and checked again but no success came of that. However, the last thing I tried was to overwrite all files in the C4PICs3 directly with a copy from my old machine. This was a success with the exception of the PIC launcher all is working f...

Re: USB cable not connected
Thanks for the advice but so far no go. I have un insatalled Flow code V3 and I am concentrating on C4PICS. There seems to be several issues here regarding the locating of the files such as PPP which may have something to do with the launch of these programs. The device manager indicates that the HP...

V3 Oscillator cap values
Hi,
I am having difficulty reading the compnent values on the HP488-00-3 Data sheet.
In particular the oscillator capacitor values. Actually, all component values.
Is a more readable circuit diagram available or may be a parts list?
Thanks
