Hi Rob

 

I asked SNAP support and this was the answer:

 

Peter,

Unfortunately this device requires High Voltage to program (we do not support the PGM pin) and since MPLAB Snap does not support High Voltage this device cannot be supported with MPLAB Snap.

 

I would recommend you get a MPLAB PICkit 4 as that does support this device.

Regards,

Strange: you have to buy two programmers. SNAP for LVP and Pickit4 for HVP.

So I don’t have to look for updates for the SNAP. It’s impossible.

Regards,

Peter

Hi Peter,

 

I hope that they will fix this but if I look at the investigation of Rob Hamerling I am not sure they will fix it for your specific PIC. If not you might need to switch to another PIC type...

 

Kind regards,


Rob

Hi all,

 

I found this info in the  Microchip forum.

MPLAB Snap Support

The MPLAB Snap In-Circuit Debugger/Programmer supports many, but not all, PIC MCUs and dsPIC DSCs at this time. The firmware is continually being upgraded to add support for new devices. For the most current list of supported parts, review the latest release notes located in MPLAB X IDE . To request device support or to report issues, email:  &nbsp [email protected] 

 

 

So give it a try.

 

Kind regards,

 

Rob

Hello Peter, Rob and others,

I will wait for the next update of Microchip.

 


Finally I found a table which shows which devices are supported by which tools.
The table is on my Linux system with MPLABX 5.35 in:

file:///opt/microchip/mplabx/v5.35/docs/Device Support.htm


I suppose with Windoz it will be on a similar place.

The table shows a.o. indeed that the 18F4455 is not supported by Snap (with this version of MPLABX).

Regards, Rob.
