- A [Teensy 4.0](https://www.pjrc.com/store/teensy40.html)/[Teensy 4.1](https://www.pjrc.com/store/teensy41.html)/[Teensy MicroMod](https://www.sparkfun.com/products/16402) development board
|
||||||
|
|
||||||
|
The following software tools have to be installed:
|
||||||
|
- Python3 (as `python3`, or modify `run.py` to use the `python` binary)
|
||||||
|
- [`cargo-binutils`](https://crates.io/crates/cargo-binutils)
|
||||||
|
- [`teensy_loader_cli`](https://www.pjrc.com/teensy/loader_cli.html)
|
||||||
|
|
||||||
|
|
||||||
|
### Run
|
||||||
|
|
||||||
|
- Connect the Teensy to PC via USB cable.
|
||||||
|
- Press the `Reset`/`Boot` button on the Teensy.
|
||||||
|
- Run:
|
||||||
|
```bash
|
||||||
|
cargo run --release
|
||||||
|
```

// of 2^31 ticks. The Clock counter value is 32 bits, so one "overflow cycle" is 2 periods.
|
||||||
|
//
|
||||||
|
// A `period` count is maintained in parallel to the Timer hardware `counter`, like this:
|
||||||
|
// - `period` and `counter` start at 0
|
||||||
|
// - `period` is incremented on overflow (at counter value 0)
|
||||||
|
// - `period` is incremented "midway" between overflows (at counter value 0x8000_0000)
|
||||||
|
//
|
||||||
|
// Therefore, when `period` is even, counter is in 0..0x7FFF_FFFF. When odd, counter is in 0x8000_0000..0xFFFF_FFFF
|
||||||
|
// This allows for now() to return the correct value even if it races an overflow.
|
||||||
|
//
|
||||||
|
// To get `now()`, `period` is read first, then `counter` is read. If the counter value matches
|
||||||
|
// the expected range for the `period` parity, we're done. If it doesn't, this means that
|
||||||
|
// a new period start has raced us between reading `period` and `counter`, so we assume the `counter` value
|
||||||
|
// corresponds to the next period.
|
||||||
|
//
|
||||||
|
// `period` is a 32bit integer, so it overflows on 2^32 * 2^31 / 1_000_000 seconds of uptime, which is 292471 years.
