Rust on the Microchip SAMD51 on the Adafruit Metro M4 Express Board #Rust #RustLang #Adafruit @rustlang @rustembedded @bascule @MicrochipMakes

Heading over to GitHub provides the details that Paul (sajattack) has successfully ported Rust to the SAMD51 based on the ATSAMD Rust effort originally targeting the SAMD21.

The repo states it holds various things that support/enable working with atmel SAMD21 based devices, such as the Adafruit Metro M0, Trinket M0 and Gemma M0, using Rust.

In addition to the generic crates, there are also crates for popular ATSAMD21 based development boards. They aim to rename pins to match silk screens or Arduino pin assignments, add helpers for initialization, and re-export the atsamd21-hal crate.

• arduino_mkrzero
• circuit_playground_express
• feather_m0
• gemma_m0
• itsybitsy_m0
• metro_m0
• samd21_mini
• trinket_m0
• sodaq_one

Ed.: I’m sure the SAMD51 provides the extra flash and RAM to make Rust on Microcontrollers a more seamless experience (at least it is for CircuitPython).

The SAMD21 code is in the GitHub repo under Apache 2.0 and MIT licenses. You can see the SAMD51 pull request here.
