How to use spi to write and read some specfic register address

May I ask which time zone you are in?

I'm in CST 6 hours behind GMT. Getting a bit late for me, so trying to make a determination of how long I might choose to hang in there this evening.

Did you see the code example at:

Have you tried using setWatch(io_RunMode, . . . . . or would that even be appropriate?

It's not clear to me yet how the device is desired to be used and what data is required.
