16C73 to a F873
PostPosted: Thu Jan 27, 2005 11:30 pm     Reply with quote
Anyone have any pointers on migrating code from a 16C73 to a 16F873?

I have a fairly simple program that works fine on a 73 but doesn't do anything on an F873.

Thanks,

The most likely reason is that the 16F873 is shipped with Low
Voltage Programming enabled. So you need to disable it by
adding NOLVP to the end of your #fuses statement.

Just figured it out.. My Picstart Plus Programmer is too old!!
The programing doesn't fail, but it doesn't actually program either.

Thanks!
