Hi all,

When I select the PIC 12LF1840, a message appears "Unknown Chiptype". And when I confirm the chip, another message "could not set selected chip".

Have you tried compiling with 12F1840 instead?
If compiles OK, should work on your 12LF1840 device when it turns up.

Hello Martin,

Yes, I compiled and no errors.
I will order this type of PIC and test in real situations.

thank you

hello,

Well, I got the PIC and I could program it. Everything is ok.

These errors occur when I change the type of PIC in an existing program.
