I just purchased a waysmall 400xm-bt to use in a car project, and I have
a couple of questions. I've been surfing the mailist archives looking
for information, and have found quite a bit. I still have a question
regarding GPIO. Does the waysmall 400xm-bt have a free GPIO pin I can
use? It's the stock unit that is offered off the website. I have a
little custom circuitry that will use the state of the car (on or off)
to drive a pin high or low. I can then use the state knowledge to slow
the proc down, turn off the USB port, and turn off the bluetooth radio
to drop power consumption a bit. The power draw is too low to care too
much about putting it to sleep, and the coding effort to get
sleep/standby to work might be more than the power savings is worth. If
the unit doesn't have a free pin, what can I buy for this setup that
does? I'll be OK if someone tells me I have to buy a different unit to
get what I want, I bought this setup before I realized it didn't specify
free GPIO resources. And for now, I'm less worried about power and more
worried about getting it all to work.
Thanks for any help.
So take it as a complement when people say you look Funny.
