This is the forth post in a weekly series tracking the development of Tock, a safe multi-tasking operating system for microcontrollers.

What’s new in Tock?

• We started a mailing list for people working on Tock or ports of Tock to various chips and platforms.

• The mailing list has been innagurated with a discussion of faster interrupt handling, LLVM changes that make Rust processes feaible and a directory tree restructure

• @idolf did a complete pass cleaning up the source with rustfmt.

• @emosenkis replaced instances of the unstable volatile_load/volatile_store calls with their stable variants write_volatile/read_volatile.

• @alevy implemented a minimal driver for a Synposis USB IP (so far it only does enough setup to register as device on a Linux host).

• @bradjc has been making progress on sensor drivers for the Signpost project.
