Hi everbody I have connected the 32 outputs of one circuit to 4 PISO's to connect these outputs to a PIC16C745 into the digital inputs. The problem is that I have connected everything like the datasheet, but in the serial output of the PISO only exit the H data, only the firt data of the data chain,...

I think I have solve the problem, I think that the input clock of the register is too much sensible to the transitions, by this reason I have changed the 74HC164 to 74HC4094 and I have put a resistor to the clock to do with less transition the clock. I will try to do some test more to the circuit, a...

I have connected the dif¡gital signals of the PIC, RB0.
The CLR is not connected to a 10k resistance is connected directly to Vcc.
B is connected directed to Vcc

I can sometimes that the circuit works but putting 10 omhs in the clock and 10K to every input and output, but it only works sometimes.

I have one design with a PIC16C745 after the pic I have conected a SIPO or shift register (the 74hc164 or 74hc4094) to have more conections for the rest of the circuit, but when I send a chain of information, the register put every pin to one or to cero depends almost the times from the first bit: i...
