GPIO
Here describes how to use GPIO
PS_MIOxx
You can operate PS_MIOxx(x is a numeral) by Linux sysfs which is described in an official documentation.
Before accessing sysfs, configure your module to enable GPIO by our program.
$ # initialize gpio by DMP program
$ cd /home/ubuntu/dv-sdk/utils/ && make
$ sudo ./reset_mio_c3 xx
$ # /sys/class/gpio/gpioxx/ is created.
$ echo $(( $(cat /sys/class/gpio/gpiochip*/base) + xx )) > /sys/class/gpio/export
$ # You can get information by `cat /sys/class/gpio/gpioxx/{direction,value,edge,active_low}`.
$ # See [https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Documentation/gpio/sysfs.txt?h=v4.14.96] for each file.
$ # finalize
$ echo $(( $(cat /sys/class/gpio/gpiochip*/base) + xx )) > /sys/class/gpio/unexport
C programs can operate as well. See Xilinx-Wiki.
NOTE PS_MIO32/PS_MIO33/PS_MIO42 are reserved and not avaiable to users.
