Low voltage PICs and LVP

Hi,
I am about to program 18LF2520 PICs which are low voltage, has this anything to do with low voltage programming LVP?

No! The LVP is a wondrous idea! You can use the same system voltage to program the device. However... Once a device is set to Low Voltage Programming.. RE3 is then unavailable as a IO pin...

Hi I,
"You can use the same system voltage to program the device." What does this mean?

I have a Pickit3 circuit that allows LVP, but from earlier posts, I think I can avoid it.

I would like to program the PICs using only the Pickit3 set to 3.3v, or am I getting programming voltages mixed up with PIC power voltages?

Hi,
I've hit a buffer.
Just finished setting up the header file, config bits and FREQ, then couldn't save it. See attached?

Hi,

EDIT: Unable to post images.
I get a pop-up saying "Files newxc8_header.h was changed to read only! Can not save it."
Any ideas?

EDITx2: Done it!!

You are trying to save to a directory that you're not allowed to....

You need to download hoversnap.... This lets you snapshot parts of the screen...

Hi,
As mentioned, new computer! I use Irfanview, as hoversnap, I haven't updated all of the addons yet.
Cheers, C.
