Hi folks!
I'm a newbie here, and need your help for my very first sketch.
I need some configuration pins to have an action,
and a reset pin that is set OFF by default (HIGH).
Each time the configuration takes place, the RST pin should be active (LOW),
when configuration done, it should return and remain OFF (HIGH).
All pins work perfectly, and stay fixed in their condition,
except for the RST pin, where I get a pulsed waveform.
I know there is a simple fix for this.
Can you help me?
Thanks in advance.
