Mrt V5.52

[Lucy Ginsburg]

Check the device selected in MPLAB IDE (PIC18F45K80) is the same one that physically attached to the debug tool. Selecting a 5V device when a 3.3V device is connected can result in damage to the device when the debugger checks the device ID. Do you wish to continue?

Note: If you would like to program this device using a low voltage programming, select CANCEL on this dialog. Then go to the PICkit 3 node of the project properties and check the Enable Low Voltage Programming check box of the Program Options Options Category pane (low voltage programming is not valid for debugging operations)."

Thanks Paul. The programs are pre-built and readied for this controller. Originally, the controller was installed with MPLAB IPE V3.35, but that is no longer available. The process for using that loader was clear. Using MPLABX-v5.52 is not the same, so its difficult to know what the output means. What I have seen with others is that they ignore that message and continue to program, but I am suspect and cautious. I am hoping someone can interpret a bit. All the connections are per the instructions.

However as @ReidLandsrud mentioned new versions of MPLAB IPE are included with new versions of the MPLAB X IDE and should be nearly identical in setup and usage (Microchip intentionally makes few changes to the UI of the IPE).

I open the IPE, connect the PICkit 3 to the chip. It does not recognize it .

I open the 5v supply to the circuit. The IPE shows me the Chip selected, and the serial number of the PicKit3.

When I click on connect. It shows Connection failure.
