I have an application I am building using:
Connex 400xm (not bluetooth)
On the breakout I am using the HWUART, FFUART, and LCD. What I am looking for
is the best place to wire a reset button and LED or 2 (maybe a tristate if it
is more convienent than 2 LEDS. What is the best way to do this? Should I use
the PWM pins and Which GPIO do they map to? I am asking because I am using so
much IO I am afraid of overloading the IO. I use the CF, network, LCD, and 2
serial ports throughout the application. Do I have a few spare IOs? Any help
would be great.
PS a pointer to a wiki page is considered an answer, but I looked and could
not answer my question definitively.
