Installation

• Click on the 'Download zip' button to the right.
• Unzip the archive and rename resulting folder to 'SPIFlash'
• Move the folder to your libraries folder (~/sketches/libraries)

Usage

The library is called by declaring theSPIFLASH flash(csPin) constructor where 'flash' can be replaced by a user constructor of choice and 'csPin' is the Chip Select pin for the flash module.
Make sure to include #include<SPI.H> when you include #include<SPIFlash.h>.

The library enables the following functions: (For further details on the functions refer to README.md)

Get JEDEC ID

getID ()

---

Continuous read commands

beginRead(address)

readNextByte()

endRead()

---

Read commands

readByte(page, offset)

readPage(page_number, *page_buffer, outputType)

---

Write commands

writeByte(page, offset, data)

Writes a byte of data to a specific location on a page. Takes the page number (0-4095), offset of data byte within page (0-255) and one byte of data (0-255) as arguments.

writePage(uint16_t page_number, uint8_t *page_buffer)
