#define DATAFLASH_CHIP_MASK | ( | index | ) | __GET_DATAFLASH_MASK(index) |
static void Dataflash_DeselectChip | ( | void | ) | [inline, static] |
Deselects the current dataflash chip, so that no dataflash is selected.
static uint8_t Dataflash_GetSelectedChip | ( | void | ) | [inline, static] |
Determines the currently selected dataflash chip.
static void Dataflash_Init | ( | const uint8_t | PrescalerMask | ) | [inline, static] |
Initializes the dataflash driver (including the SPI driver) so that commands and data may be sent to an attached dataflash IC.
[in] | PrescalerMask | SPI prescaler mask, see SPI.h documentation |
static uint8_t Dataflash_ReceiveByte | ( | void | ) | [inline, static] |
Sends a dummy byte to the currently selected dataflash IC, and returns the next byte from the dataflash.
static void Dataflash_SelectChip | ( | uint8_t | ChipMask | ) | [inline, static] |
Selects the given dataflash chip.
[in] | ChipMask | Mask of the Dataflash IC to select, in the form of DATAFLASH_CHIPn mask (where n is the chip number). |
static void Dataflash_SelectChipFromPage | ( | const uint16_t | PageAddress | ) | [inline, static] |
Selects a dataflash IC from the given page number, which should range from 0 to ((DATAFLASH_PAGES * DATAFLASH_TOTALCHIPS) - 1). For boards containing only one dataflash IC, this will select DATAFLASH_CHIP1. If the given page number is outside the total number of pages contained in the boards dataflash ICs, all dataflash ICs are deselected.
[in] | PageAddress | Address of the page to manipulate, ranging from ((DATAFLASH_PAGES * DATAFLASH_TOTALCHIPS) - 1). |
static void Dataflash_SendAddressBytes | ( | uint16_t | PageAddress, | |
const uint16_t | BufferByte | |||
) | [inline, static] |
Sends a set of page and buffer address bytes to the currently selected dataflash IC, for use with dataflash commands which require a complete 24-byte address.
[in] | PageAddress | Page address within the selected dataflash IC |
[in] | BufferByte | Address within the dataflash's buffer |
static void Dataflash_SendByte | ( | const uint8_t | Byte | ) | [inline, static] |
Sends a byte to the currently selected dataflash IC, and ignores the next byte from the dataflash.
[in] | Byte | of data to send to the dataflash |
static void Dataflash_ToggleSelectedChipCS | ( | void | ) | [inline, static] |
Toggles the select line of the currently selected dataflash IC, so that it is ready to receive a new command.
static uint8_t Dataflash_TransferByte | ( | const uint8_t | Byte | ) | [inline, static] |
Sends a byte to the currently selected dataflash IC, and returns a byte from the dataflash.
[in] | Byte | of data to send to the dataflash |
static void Dataflash_WaitWhileBusy | ( | void | ) | [inline, static] |
Spinloops while the currently selected dataflash is busy executing a command, such as a main memory page program or main memory to buffer transfer.
