スミス sumisu

Sumisu is the repo for Smith

Setup

1. git clone git@github.com:hello/sumisu.git sumisu
2. git submodule update --init --recursive
3. for an initial build, configure the app and platform

./config.sh ${APP} ${PLATFORM}
example: ./config test nrf52

4. after that, just run ./config.sh again to build the same setup, or run make in the build folder
5. all binaries and jlink flash scripts will be generated in the bin folder

• to flash an application:

./tools/scripts/jlink_cli.sh < bin/${APPNAME}.jlink

• to open up a RTT console:

TODO: make this easier to invoke

./tools/scripts/jlink_cli.sh, in subsequent cli
r
g
./tools/jlink/JLinkRTTClient

• Alternatively, if UART is used as the console:

screen /dev/cu.USB${ID} ${BAUDRATE} -flow on

Toolchain

• CMake
• gcc-arm-non-eabi
• Segger JLink

Architecture

A Smith project is composed of an app and a platform, linked together by an os layer

• app is the device-agnostic, high level code which defines the business logic of the project.

• platform contains the platform specific drivers and implementation of the os layer.
  In addition, a platform also implements the cmsis_rtos via a native OS.

  The following platforms are supported

  • nrf52832 + FreeRTOS
  • darwin + pthreads

• os is based on the cmsis_rtos API. It provides hardware abstraction via services as well as all the OS specific functions.
