Detailed Description

What the panel's SD (Secure Digital) card slot holds, as the last mount found it: no card, a mounted volume, a card with no FAT (File Allocation Table) volume on it, or a card that does not mount for another reason.

The panel's storage component sets it; the screens, the alerts and the start-up line read it to say which of the four it is (ui_card_text.h). The values are stable: the programmer's feed carries one as a uint8_t.

Enumeration Type Documentation

card_state_t

enum card_state_t

Mount state of the SD card.

Enumerator
CARD_STATE_NONE	No card answers in the slot, or no mount was tried yet. Zero, so a zeroed feed reads as no card.
CARD_STATE_MOUNTED	A volume is mounted.
CARD_STATE_NO_FAT	A card answers, and FatFs finds no FAT12, FAT16, FAT32 or exFAT volume on it (FR_NO_FILESYSTEM, 13): NTFS, a GPT or no format at all.
CARD_STATE_UNREADABLE	A card answers, or the slot's bus did not come up, and the volume does not mount for another reason: a read error, a card that does not finish its start-up, no memory for the mount.
