Raspberry-W25Q64

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

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

Software requirement

• WiringPi Library
  This project uses the wiringPiSPISetup() function to initialize SPI, and use /dev/spidev0.0.
  If you use it on a board other than the RPI board, you may need to change the SPI device.
  As far as I know, there are these libraries.
  • WiringPi for OrangePi
  • WiringPi for BananaPi
  • WiringPi for NanoPi
  • WiringPi for Pine-64

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(Winbond only)
uint8_t W25Q64_readStatusReg2(void);

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

// Get Unique ID(Winbond only)
void W25Q64_readUniqieID(uint8_t* id);

// 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);

Wireing

Winbond

• W25Q80
  

JEDEC ID:
Byte1 : ManufacturerID(0xef=Winbond)
Byte2 : MemoryType(0x40=SPI/0x60=QPI)
Byte3 : Capacity(2^0x14=2^20=0x100000=1M Byte=8M Bit)

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

• W25Q16
  

• W25Q32
  

• W25Q64
  

• W25Q128
  

MACRONIX

• MX25L3206E
  

JEDEC ID:
Byte1 : ManufacturerID(0xc2=Macronix)
Byte2 : MemoryType(0x20)
Byte3 : Capacity(2^0x16=2^22=0x400000=4M Byte=32M Bit)

Note

I tested these.
But I couldn't get it working.
