Re: Going crazy with PIC16F and 74HC595 serial-parallel regi
Solved.
It is possible to drive a 595 with 2 wires:
- serial data in
- shift and latch clocks tied together
You have to add one clock up/dw because (like in the datasheet) latch clock is one step behind shift clock when tied...
Re: Using a 74HC595 serial/parallel register with a single c
I've solved the problem.
There was a bug in communication code.
Now I can drive the 595 with those 2 wires:
- serial data input
- shift and latch clocks tied together
I had to add one more clock up/dw because, as the datasheet...
Hi,
did anybody try to use a 74HC595 connecting together the shift and the latch clock to use only two wires (data and clocks)?
I'm trying to do this but I have strange results until the chip gets locked (the output doesn't change).
Any suggestion?
Thanks

Hi,
I'm new here, I've found this very interesting forum by internet search and, so, I subscribed.
I'm writing because I'm going crazy with a very basic problem:
I'm using a PIC microcontroller to drive a Philips 74HC595 serial-parallel register. I've seen discussions about...
