I thought that the AVR has Schmitt trigger inputs when a port is configured for digital input. This is called a “preset” function. JoeN on Oct 09, Here’s how I use the switches to duplicate what the MCU does: Clock falling doesn’t do a thing, as you would expect.

In either case, after the clock rises, Q6, Q7, and Q8 are available on their respective output pins. CDBE with buttons and leds Q8. All bets are off until you debounce the push button driving the clock input – you will be getting anything from 1 to hundreds of edges everytime you press it at the moment.

What does Q1 Internal mean? I read the truth table simply.

The first one was wrong, the 8 input switches should be connected to VDD, not ground. I’ve just updated the schematic image.

Input s n – HIGH I did this with one of the 8 inputs and in another test with two inputs simultaneously 3. Q7 goes into Q8. Input s n – LOW 5. Under these conditions, the chip does not advance these 8 bits at all and SER IN is completely ignored.

Mechanical switches should never drive logic clocks directly for this reason! I will never ask you to do anything that I wouldn’t do myself. JoeN Edison Member Posts: CDBE with buttons and leds. Data Sheet for the CD Basically I’m duplicating what a MCU does but at very slow speed. I did this before with a 74HC shift register and it clarified for me how it functions, but with the CD it’s a different story.

PE – LOW 6. I’ve found some code online but unfortunately it is not helpful for understanding how the datasneet register works. It looks like a weird serial-in, last-three-bits-out, with parallel 8 bit preset shift register to me. What does Qn-1 do? MarkT on Oct 06, Is datxsheet not happening? Here is it in English. Have you hit all pins with a logic probe to make sure they have the voltage you think they do?

CD BE – Understanding the truth table. That is what the data sheet says, at least. I’m not sure if this is the correct way to do it but I got some results that I don’t understand.

CD – Q8 output.

vd4014 MarkT Brattain Member Posts: CD – truth table. While doing the tests I wrote down the output state of Q8.

According to the output table image CD – Q8 output.
