Hello all I'm French and I do a Central <supervision with an excel acquirable.
I did a program with a pic 18F4620 and 5 DS18B20
scanning work well as display the transmission as long as the PICkit3 plugged if I unplugged the series connection sending anything.
Have you ever encountered this problem and can you help me if needed
best regards
pullup resistor missing?
How are you handling MCLR?
hello only with a button or a power cycle
Try turning MCLRE to OFF in the configuration.Quote:

i put mclre off but it's the same thing, my version of PBP is 2.60
f I unplugged PICkit3 and I reset the prog runs it displays me the correct values on the displays, given series are erroneous if I reconnect the PICkit3 reset this and the serial data is ok
My best guess would be a grounding issue. Evidently you are powering the PIC independent from the PC. When the PicKit is connected it changes the potential on the zero rail (ground).
thank you for directing me to the problem of mass it was indeed a mass between my converter and my plate 'I was thinking more of a problem config 18f thank you again
