There are three methods to control the LEDs: stateless, userspace daemon, kernel module.
- **stateless**: the simplest way is to directly build and run the `ugreen_leds_cli` tool. It will find and communicate with `/dev/i2c-X`, and does not save the current state of LEDs. Therefore, we are unable to implement the stateful functions like blink an LED once, unless manually maintaining the states.
- **userspace daemon**: it also communicates with `/dev/i2c-X`, but will maintain the LEDs' states and create a socket `/tmp/led-ugreen.socket`. The tool `ugreen_leds_cli` will communicate with the daemon via the socket. This method allows a similar function like the `oneshot` trigger in the kernel module. You can run `ugreen_leds_cli disk1 -oneshot 100 100` to setup the trigger and run `ugreen_leds_cli disk1 -shot` to blink `disk1` once. To use this daemon, you should first run `ugreen_daemon` and then use `ugreen_leds_cli` as before. The `ugreen-diskiomon` script requires this control method or the kernel module below.
- **kernel module**: it will register LEDs in `/sys/class/leds`, therefore, any triggers supported by the kernel are also usable.
- **userspace daemon**: it also communicates with `/dev/i2c-X`, but will maintain the LEDs' states and create a socket `/tmp/led-ugreen.socket`. The tool `ugreen_leds_cli` will communicate with the daemon via the socket. This method allows a similar function like the `oneshot` trigger in the kernel module. You can run `ugreen_leds_cli disk1 -oneshot 100 100` to setup the trigger and run `ugreen_leds_cli disk1 -shot` to blink `disk1` once. To use this daemon, you should first run `ugreen_daemon` (it won't exit, keep it running) and then use `ugreen_leds_cli` as before. The `ugreen-diskiomon` script requires this control method or the kernel module below.
- _TL;DR_: copy `ugreen_daemon` and `ugreen_leds_cli` to `/usr/bin`; keep `ugreen_daemon` running; then keep `scripts/ugreen-diskiomon` running.
- **kernel module** (suggested): it will register LEDs in `/sys/class/leds`, therefore, any triggers supported by the kernel are also usable.
The `ugreen_leds_cli` tool is suitable for all three methods. It will first check whether `/tmp/led-ugreen.socket` exists, and then check whether `/sys/class/leds` contains corresponding LEDs. If both of them do not exist, then it will try to use the stateless method.
