Am I the only person that can't stand having VSS above, and VDD below?
I had to go and fix the caps so VDD was above, and VSS below.

This is my offer for the smallest design on the MCP23017 I/O expander in bi-directional mode:

It's possible to smoosh an SOIC with 0603 SMD down to 23mm x 107mm (0.9in x 4.2in), with no...
The original project was just a personal home alarm system.
But now I'm designing a controller for flight sim that I plan on marketing. I'm considering using a combination of everything said in...
Car automakers had to do it with better electrical characteristics I guess.
I'd also choose 2 wires USART classic setup. Tested and guarrateed to work just fine.

I saw a mention further up the thread about 1-wire comm.
OBD-II signal protocols. ISO 9141-2. This protocol has an asynchronous serial data rate of 10.4 kbit/s. It is somewhat similar to RS-232;...
Me too. But if I removed my post, the thread closed again.

could do.........
1)

restarting:
pause 1000 ............... wait a second or 2 to reset all
@ RESET

or 2)................
if all slaves are on same 5 or 3 volt supply, then use a small...
A tri-state general I/O pin on the master.
Output low = reset
Input = do nothing
I can't say. This is all theory for now, but is supported by posts on google and a forum elder,...
But will that work if the slave is caught in a loop or some such?
I'm aiming for a complete reset with no decision from the slave.
