class Flash – access to built-in flash storage¶
This class gives access to the SPI flash memory.
In most cases, to store persistent data on the device, you’ll want to use a higher-level abstraction, for example the filesystem via Python’s standard file API, but this interface is useful to customise the filesystem configuration or implement a low-level storage system for your application.
Methods¶
- Flash.readblocks(block_num, buf)¶
- Flash.readblocks(block_num, buf, offset)
- Flash.writeblocks(block_num, buf)¶
- Flash.writeblocks(block_num, buf, offset)
- Flash.ioctl(cmd, arg)¶
These methods implement the simple and extended block protocol defined by
os.AbstractBlockDev
