I/O library for Microchip SST25 flash memory series

Non-blocking crate for interacting with Microchip SST25 flash memory devices like SST25VF080B.

Currently, the following features are implemented:

• Reading memory
• Writing single bytes
• Auto-address-increment writes
• Full chip erase
• Reading status
• Writing status

Example

For all details see monitor module.

use mc_sst25::device::Flash;
use mc_sst25::example::{MockBus, MockPin};

let bus = MockBus::default();
let pin_en = MockPin::default();
let pin_hold = MockPin::default();
let pin_wp = MockPin::default();

let mut device = Flash::new(bus, pin_en, pin_wp, pin_hold);

// Writing a single byte
device.erase_full().unwrap();
device.byte_program(0x0, 0x66).unwrap();

// Writing larger data
device.aai_program(0x1, &[0x1, 0x2, 0x3, 0x4]).unwrap();

// Reading data starting at address 0x0
let data = device.read::<5>(0x0).unwrap();
assert_eq!([0x66, 0x1, 0x2, 0x3, 0x4], data);

State

⚠️ The crate has only been tested for the SST25VF080B variant.
