currently I have connected 8 LEDs on these GPIO pins and easily i can access them bit by bit using WRITE_PIN and READ_PIN using gpio-mmap.h file,
These LEDs are glowing according to given values,.
But I want to access all pin at once as a GPIO Port so that I can read all 8 bits in single cycle When I use GPIO_BASE macro from gpio-mmap.h , it given an error "Segmentation fault"..
I am unable to read them, any body can help regarding this topic....
Thanks and Regards,
