| libgpiod v0.1 |
| ============= |
| |
| First version of libgpiod. |
| |
| It's currently possible to: |
| - get and set the values of multiple GPIO lines with a single function call |
| - monitor a GPIO line for events |
| - enumerate all GPIO chips present in the system |
| - enumerate all GPIO lines exposed by a chip |
| - extract information about GPIO chips (label, name, number of lines) |
| - extract information about GPIO lines (name, flags, state, user) |
| |
| Tools provided with the library are: |
| - gpioget - read values from GPIO lines |
| - gpioset - set values of GPIO lines |
| - gpiodetect - list GPIO chips |
| - gpioinfo - print info about GPIO lines exposed by a chip |
| - gpiomon - monitor a GPIO line for events |
| - gpiofind - find a GPIO line by name |
