| -------- |
| Overview |
| -------- |
| This sys I/O backend implements the ``pw_sys_io`` facade. To enable, set |
| ``CONFIG_PIGWEED_SYS_IO=y``. Once enabled, I/O operations will be routed to |
| Zephyr's console. Additionally, it is possible to enable the USB subsystem |
| by setting ``CONFIG_PIGWEED_SYS_IO_USB=y``. |
| |
| The I/O backend initializes during Zephyr's ``APPLICATION`` level and uses |
| ``CONFIG_PIGWEED_SYS_IO_INIT_PRIORITY`` to set the priority level. This config |
| value defaults to 1, but is configurable via Kconfig. |
