Driver for the MX25R chip

mx25r-rs

Platform-agnostic Rust driver for the macronix MX25R NOR flash using the embedded-hal.

This driver implements all the commands available to the MX25R chip series, but qspi is not supported yet. Note that the drivers are low level to allow the user to write custom implementation for its needs.

Usage

You can see an example of the usage for the nRF52840-DK in the examples directory. For now only a blocking API is available.

Things to consider when using the driver crate

• Enable write before erasing sector/block/chip or writing data to the memory
  • Even when using the embedded_storage NorFlash trait
• Poll the wip bit before read/write/erase operation, if not the request will be ignored
• write_security_register is not a reversable operation, make sure to read the datasheet.

Nix

A nix flake is available to ease development and dependencies for the examples.
