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. CD BE – Understanding the truth table.

This is called a “preset” function. I read the truth table simply. According to the output table image CD – Q8 output. Is this not happening? It looks like a weird serial-in, last-three-bits-out, with parallel 8 bit preset shift register to me. Have you hit all pins with a logic probe to make sure they have the voltage you think they do? Mechanical switches should never drive logic clocks directly for this reason!

Here’s how I use the switches to duplicate what the MCU does: CD – truth table. The first one was wrong, the 8 input switches should be connected to VDD, not ground. Q7 goes into Q8. JoeN Edison Member Posts: I’ve found some code online but unfortunately it is not helpful for understanding how the shift register works.

I will never ask you to do anything that I wouldn’t do myself. I’ve just updated the schematic image. Datasehet these conditions, the chip does not advance these 8 bits at all and SER IN is completely ignored.

Input s n – LOW 5. Input s n – HIGH I did this with one of the 8 inputs and in another test with two inputs simultaneously 3. What does Q1 Internal mean?

Basically I’m duplicating what a MCU does but at very slow speed. In either case, after the clock rises, Q6, Q7, and Q8 are available on their respective output pins. Data Sheet for the CD CDBE with buttons and leds. 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.

I’m not sure if this is the correct way to do it but I got some results that I don’t understand. CDBE with buttons and leds Q8. MarkT Brattain Member Posts: JoeN on Oct 09, I thought that the AVR has Schmitt trigger inputs when a port is configured for digital input.

CD – Q8 output. PE – LOW 6.

Clock falling doesn’t do a thing, as you would expect. Here is it in English. That is what the data sheet says, at least.
