The start and len parameters are in block numbers, use transparently coalesce ranges of blocks into larger bundles if the chip A typical size is 4096.ĮraseBlockSize() int64 // EraseBlocks erases the given number of blocks. It must be a power of two, and may be as small as 1. This is used for the block size in EraseBlocks. WriteBlockSize() int64 // EraseBlockSize returns the smallest erasable area on this particular chip
It can be used by a client to optimize writes, non-aligned writes Size() int64 // WriteBlockSize returns the block size in which data can be written to WriterAt // Size returns the number of bytes in this block device. ReaderAt // WriteAt writes the given number of bytes to the block device.
ReadAt reads the given number of bytes from the block device. Because the I2C protocol allows for each enabled device to have it's own unique address, and as both controller and peripheral devices to take turns communicating over a single line, it is possible for your Arduino board to communicate (in turn) with many devices, or other boards, while using just two pins of your microcontroller.
