NOTE: storage_idle_notify usage notes..
|
|
|
|
1) The callbacks are called in the ata thread, not main/your thread.
|
|
2) Asynchronous callbacks (like the buffer refill) should be avoided.
|
|
If you must use an async callback, remember to check storage_is_active() before
|
|
accessing the disk, and do not call any functions between that check and the
|
|
disk access which may cause a yield (lcd_update() does this!).
|
|
3) Do not call any yielding functions in the callback.
|
|
4) Do not call storage_sleep in the callbacks.
|
|
5) Don't Panic!
