DS1302 in PIC16F648A |

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. |
