Raspberry-W25Q64

SPI Flash Memory W25Q64 Access Library for RaspberryPi
I ported from here.

https://github.com/Tamakichi/Arduino-W25Q64


Build

git clone https://github.com/nopnop2002/Raspberry-W25Q64
cd Raspberry-W25Q64
make

API

// Start Flash
void W25Q64_begin(uint8_t spich);

// Get status register1
uint8_t W25Q64_readStatusReg1(void);

// Get status register2
uint8_t W25Q64_readStatusReg2(void);

// Get JEDEC ID(Manufacture, Memory Type,Capacity)
void W25Q64_readManufacturer(uint8_t* d);

// Get Unique ID
void W25Q64_readUniqieID(uint8_t* d);

// Check busy
bool W25Q64_IsBusy(void);

// Set power down mode
void W25Q64_powerDown(void);

// Set write enable
void W25Q64_WriteEnable(void);

// Set write disable
void W25Q64_WriteDisable(void);

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

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

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

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

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

// Erase all data
bool W25Q64_eraseAll(bool flgwait);

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

Output

w25q64-1

JEDEC ID:
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
