DS1302 in PIC16F648A

[digisol]

Hello!
I have a PIC16F84A using driver DS1302 running in a protoboard.
I need to use the same code with ds1302 driver in a PIC16F648A,
I am using (in both PICs):

#define RTC_SCLK PIN_B4
#define RTC_IO PIN_B5
#define RTC_RST PIN_B6

It does not work with 648A pic!

I made a new pic wizard project for the PIC16F648A.
If I place the PIC16F84A in place of the PIC16F648A it woks, so the wiring is OK!

Any hints?

best regards

The 16F648A has low voltage programming capability.

You should add NOLVP to the end of your #fuses statement
to disable this feature.

Otherwise, a high level on RB4 will put your PIC into LVP mode,
and it will lock up.

SUPERB IT WORKS NOW.

That was the cause.

Thank you very much!!!
