* tock: use native time getter, remove globals Tock has direct support for querying time. The prior `millis()` method here replicated the same functionality, but missed some corner case concerns around overflow/wrapping. Instead, just use the native Tock time getter method. This also removes unneeded global variables and methods. * NonArduino/Tock: Update to latest libtock-c Update to the latest libtock-c commit. libtock-c now includes a libtockHal.h, so we can use that instead of the version here.

# RadioLib as Tock application
|
|
|
|
[Tock](https://github.com/tock/tock) is an embedded operating system designed
|
|
for running multiple concurrent, mutually distrustful applications on Cortex-M
|
|
and RISC-V based embedded platforms.
|
|
|
|
RadioLib can be built as a Tock application using
|
|
[libtock-c](https://github.com/tock/libtock-c). This is an example of running
|
|
RadioLib as a Tock application.
|
|
|
|
This has been tested on the
|
|
[SparkFun LoRa Thing Plus - expLoRaBLE board] (https://github.com/tock/tock/tree/master/boards/apollo3/lora_things_plus)
|
|
but will work on any LoRa compatible Tock board (currently only the
|
|
expLoRaBLE board).
|
|
|
|
libtock-c by default is bulit for RISC-V and ARM. RadioLib is also built
|
|
for both architectures by default. You can skip the RISC-V RadioLib build
|
|
by setting the `SKIP_RISCV` varaible.
|
|
|
|
The RadioLib example can be built with:
|
|
|
|
```shell
|
|
$ git clone https://github.com/jgromes/RadioLib.git
|
|
$ cd RadioLib/examples/NonArduino/Tock/
|
|
$ git clone https://github.com/tock/libtock-c.git
|
|
$ cd libtock-c; git checkout c0202f9ab78da4a6e95f136cf5250701e3778f63; cd ../
|
|
$ LIBTOCK_C_DIRECTORY="$(pwd)/libtock-c" ./build.sh
|
|
```
|
|
|
|
Then in the Tock repo you can flash the kernel and app with:
|
|
|
|
```shell
|
|
$ make flash; APP=RadioLib/examples/NonArduino/Tock/build-arm/tock-sx1261.tbf make flash-app
|
|
```
