esp-idf-w25q64

SPI Flash Memory W25Q64 Access Library for esp-idf.
I ported from here.

CONFIG

You have to set this config value with menuconfig.
CONFIG_CS_GPIO

git clone https://github.com/nopnop2002/esp-idf-w25q64
cd esp-idf-w25q64
make menuconfig
make flash

// Start Flash
void spi_master_init(W25Q64_t * dev, int GPIO_CS);

// Get status register1
esp_err_t W25Q64_readStatusReg1(W25Q64_t * dev, uint8_t * reg1);

// Get status register2
esp_err_t W25Q64_readStatusReg2(W25Q64_t * dev, uint8_t * reg2);

// Get Unique ID
esp_err_t W25Q64_readUniqieID(W25Q64_t * dev, uint8_t * id);

// Get JEDEC ID(Manufacture, Memory Type,Capacity)
esp_err_t W25Q64_readManufacturer(W25Q64_t * dev, uint8_t * id);

// Check busy
bool W25Q64_IsBusy(W25Q64_t * dev);

// Set power down mode
esp_err_t W25Q64_powerDown(W25Q64_t * dev);;

// Set write enable
esp_err_t W25Q64_WriteEnable(W25Q64_t * dev);

// Set write disable
esp_err_t W25Q64_WriteDisable(W25Q64_t * dev);

// Read data from memory
uint16_t W25Q64_read(W25Q64_t * dev, uint32_t addr, uint8_t *buf, uint16_t n);

// First read data from memory
uint16_t W25Q64_fastread(W25Q64_t * dev, uint32_t addr, uint8_t *buf, uint16_t n);

// Erase data by Sector
bool W25Q64_eraseSector(W25Q64_t * dev, uint16_t sect_no, bool flgwait);

// Erase data by block(64KB)
bool W25Q64_erase64Block(W25Q64_t * dev, uint16_t blk_no, bool flgwait);

// Erase data by Block(32KB)
bool W25Q64_erase32Block(W25Q64_t * dev, uint16_t blk_no, bool flgwait);

// Erase all data
bool W25Q64_eraseAll(W25Q64_t * dev, bool flgwait);

// Write data to memory
int16_t W25Q64_pageWrite(W25Q64_t * dev, uint16_t sect_no, uint16_t inaddr, uint8_t* buf, int16_t n);

(*) You can change any GPIO using menuconfig.

Manufacturer:
Byte1 : ManufacturerID(0xef=Winbond)
Byte2 : MemoryType(0x40=SPI/0x60=QPI)
Byte3 : Capacity(2^0x17=2^23=0x800000=8M Byte=64M Bit)

First 10Byte : ASCII 0-9
Next 32Byte : ASCII A-Z
