What does Q1 Internal mean? What does Qn-1 do? The first one was datasheeh, the 8 input switches should be connected to VDD, not ground. Under these conditions, the chip does not advance these 8 bits at all and SER IN is completely ignored.

Input s n – HIGH I did this with one of the 8 inputs and in another test with two inputs simultaneously 3.

All bets are off until you debounce the push button driving the clock datashwet – you will be getting anything from 1 to hundreds of edges everytime you press it at the moment. CDBE with buttons and leds Q8.

MarkT on Oct 06, I will never ask you to do anything that I wouldn’t do myself. I read the truth table simply. While doing the tests I wrote down the output state of Q8. CDBE with buttons and leds.

MarkT Brattain Member Posts: Here is it in English.

JoeN on Oct 09, PE – LOW 6. Clock falling doesn’t do a thing, as you would expect. I’m not sure if this is the correct way to do it but I got some results that I don’t understand. CD – truth table.

Here’s how I use the switches to duplicate what the MCU does: I’ve just updated the schematic image. Data Sheet for the CD Basically I’m duplicating what a MCU does but at very slow speed. Q7 goes into Q8. Mechanical switches should never drive logic clocks directly for this reason! Is this not dataeheet According to the output table image CD – Q8 output.

JoeN Edison Member Posts: I’ve found some code online fatasheet unfortunately it is not helpful for understanding how the shift register works. This is called a “preset” function.

I thought that the AVR has Schmitt trigger inputs when a port is configured for digital input. I did this before datasheeet a 74HC shift register and it clarified for me how it functions, but with the CD it’s a different story.

CD – Q8 output. 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? In either case, after the c4014 rises, Cd40144, Q7, and Q8 are available on their respective output pins. Input s n – LOW 5. CD BE – Understanding the truth table.

That is what the data sheet says, at least.
