gpiotool
The
gpiotool
controls the state of the GPIO lines from the CPU or any other device that drives the GPIO lines.
The CPU GPIO alines the map in Linux to
/sys/class/gpio
entries, which are manipulated through the standard read/write
interfaces. There is chip numbering to support multiple GPIO chips, or chips at an offset. For devices such as the complex
programmable logic device (CPLD) or field programmable gate arrays (FPGA),
gpiotool
accesses those devices to drive the
GPIO lines using the standard bus interfaces such as
i2c
,
mem
, or
pci
.
