8bits Serial Transmitter + Receiver using only 1 wire

Post by Xaetral »

I've just finished my serial communication modules, as you can see it's like a 8 bits register (In, Out, Write and Reset) but you can put each part in 2 different circuits and they will only need 1 single wire (yes, I mean a 1 bit wire) between them.

please note that because it's a 8bits serial communication, there is at least 8 clock cycles of latency between those 2 of course.

I have a problem with the Rx module, it is probably my fault but it might be a bug in the software;
when you put a Z state (High Impedance) on the input, it works fine, but when you don't connect any wire (witch is a Z state IRL) the simulation shows up "oscillation" and fail (and even completely freeze the simulation in case of my processor).

Can you please send your project file with steps to reproduce the issue?

hum, I think everything is here, you have the file and you just have to put the Rx module into a new circuit then put a reset button and as I said that's it

if it helps you: this bug(?) shouldn't be too much related to the other "non-connected wires" bug because my v.3 was already freezing the simulation before updating today, while the other bug occured after I did update
