LiFo Posted May 25, 2005 Report Share Posted May 25, 2005 hi just wantet to inform you i have made a Pic burner (MBHP_BURNER_V1) on a breadbord it is working fine (have just used it about 20 times to programm the same Pic18F452)BUT (there is always a but )when i first connect the burner to the pc and start the programming software the Vpp light gos on after about 5 sec.if i the go under options / hardware and push the Vpp off the vpp light goes off but comes on again after about 5 sec.i can keep doing this for ever but if i push the Vpp on and then the Vpp off then it stays off and if i close the software and start it again later it works witout the vpp going on every 5 sec.this is probably a software error but i just wantet to inform you Quote Link to comment Share on other sites More sharing options...
TK. Posted May 25, 2005 Report Share Posted May 25, 2005 Hi,I haven't noticed this effect yet, could it be that a scanner or printer driver is running in background which accesses the LPT port from time to time in order to detect a connected device? I have a similar problem when my Mustek scanner driver is activeBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
analogue_mo Posted September 25, 2009 Report Share Posted September 25, 2009 Hello everybody,I've been working with my PIC BURNER in this last couple of days, and I've been founding some problems, so, while I was browsing the forum for some answers I found this topic and decided to jump in.The exact same thing happens to me also, Vpp led goes ON when I turn the burner ON....and it only goes OFF after pressing Vpp ON and Vpp OFF buttons in PBrenner..I have no printer installed, but I have a printer emulator(that prints stuff into pdf files).....I've been getting other problems but I've created a new topic for this.cheers Quote Link to comment Share on other sites More sharing options...
