Did you really read datasheets?

relay matrix???
01/01/70 00:00
This doesn't make sense!

None of this makes sense!

It appears you need latching relays
01/01/70 00:00
Latching relay is still slow
01/01/70 00:00
You're right, but the relay spec's should reveal that
01/01/70 00:00
well, if he does ...
01/01/70 00:00
use toggle types ... they were around once ...
01/01/70 00:00
SPI + latched shift registers are good choices
01/01/70 00:00
The protocol is good ... but not necesary here
01/01/70 00:00
SPI is excellent for driving long shift registers
01/01/70 00:00
tell us, Per, what data types does SPI support?

protocol and/or command structure
01/01/70 00:00
No, SPI does *not* have both commands and data!

Where you sit determines what you see
01/01/70 00:00
Totally missing the point

Where Richard Sits......

From where I sit...
01/01/70 00:00
Always important to follow up the progress of technology

Language barrier?
