PCB Layout for multiple SPI devices.
PCB Layout for multiple SPI devices.
(OP)
Hi,
Working on my first project that has multiple slave SPI devices served by a single microcontroller.
When laying out the PCB tracks for the SPI control lines between the devices what are best design practices?
Do I simply;
Daisy-chain the control lines between the devices.
Leave absolute minimum spurs to each device.
Avoid hard right angles in the track.
I assume you should not;
Have a star type layout.
Need any form of termination resistor.
Any pointers appreciated,
Thanks, John.

Have fun! Sounds like a good introductory project.

Longer? Is that correct?

SPI is pretty forgiving as zapped sez, wire it up any way you want it.
