# Internet of Streams Project



Building a wireless sensor platform from (almost) scratch in Embedded Rust. Built with a focus on teaching embedded systems, IoT development, and Rust through live streamed coding sessions. Devices based on the [DWM1001-DEV] board, the [Nordic nRF52] microcontroller, and [Embedded Rust].

    * Get messages sending periodically

    * Receive incoming messages

    * Use the hardware random number generator

    * Serialize/Deserialize messages with `ssmarshal` and `serde`

* [2019-03-17] - **Workspace Cleanup and Alarm Clock Planning**

    * Discuss making an alarm clock as a first device

    * Discuss RTCs and how they work

    * Refactor the repo into a workspace

* [2019-03-20] - **Real Time Clock - Part 1**

    * Start implementing the nRF52 RTC peripheral

    * Write a low level peripheral driver

    * Add an interrupt handler to RTFM

    * Got stuck due to some code problems

    * Debugging a low level peripheral driver

    * Investigating what went wrong

    * Got the RTC interrupt working properly!

* [2019-03-31] - **Making an Alarm Clock - Part 1**

    * Reviewed the [`uhr` crate] for tracking wall time and alarms

    * Implemented a (re-)scheduler to allow alarms to repeat on a fixed weekly schedule

    * Wrote a no_std unit test for verifying an optimized bit-math algorithm
