I am attempting to program a PIC16F819 using the PICkit 3 and the 18 pin demo board with MPLAB X v2.15 and I cannot get the hardware to connect and program. It shows up in MPLAB with the proper serial number. I have tried running MPLAB with several different compatibilities under the program properties as well as running it as an administrator. I have tried using different USB ports as well but to no avail. I am at a loss as to what to do at this point and I would really appreciate any help that anyone could give me.
remove the USB cable form the Pickit3 and then hold the button down for 10 seconds, re-connect the USB cable while holding the button. this should force a reset and mplabx should re-program the OS in the pickit.
if not try and force the OS upgrade, this should be within MPLAB some where.
you can also try MPLAB IPE (comes with MPLABX) as i find this always upgrades when mplab doesn't.
