# 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);

The letters after the volume number indicate operating parameters.
For example W25Q64BV, W25Q64CV, W25Q64FV, W25Q64JV are all the same 8 MB flash drives, but with different maximum frequencies and speeds.
In theory you could replace slow with fast, but the other way around might not work.
- BV: 80MHz clock operation
- CV: 104MHz clock operation
- FV: 104MHz clock operation
- JV: 133MHz clock operation

The letters after the volume number indicate operating parameters.
For example, MX25L3205, MX25L3205A, MX25L3205D, MX25L3206E are all the same 4 MB flash drives, but with different maximum frequencies and speeds.
In theory you could replace slow with fast, but the other way around might not work.

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