Hello all, I have two problem about GPIO, so hope you help me 😃  
1, I’m tired to debound for GPIO.  
Can you give me some solution to debounded GPIO using software.  
2, I want using ext gpio. ( 26 pin Raspberry Pi) how to configure to use this pin ( i used mangoh Red with Wp7607).  
Tks you so much about all 🙂

Hi,  
To configure GPIO pins,

Enter to “AT” mode via “microcom -E /dev/ttyAT” in WP module after boots.  
see the GPIO current configuration in the module which shows configurations of different GPIO’s in this you can see all the GPIO’s status.  
at+wiocfg?

If the 2nd element is “0” then its unallocated We can allocate/configure it by assigning 16 to 2nd element.  
Example, AT+WIOCFG=26,16,0,0,1,0,0  
After this reboot the MangOH module to take effect of changes of “at+wiocfg”

You can use later in user space via “echo 36 \> /sys/class/gpio/export”
