PIC 16F628a .. Interfacing with H_Bridge

[mas]

I am using the PIC 16F628a ..

I take outputs from portB to the L298 IC ..

The L298 is an IC that contains 2 H_bridge circuits ..

The circuit of the PIC as well as the circuit of the H_Bridge works separatly ..

But when I connect them together something wrong happens and both are damaged ..


Is there any kind of interfacing between the 2 circuits that must be done ??

Or anyone knows what is wrong ??

Post the circuit of how you're connecting them - it sounds like you're doing something seriously wrong!.
