We are a student-run engineering group at Brown University. This project runs on our satellite, EQUiSat, which will launch in March 2018. It uses an Atmel SAMD21J18A chip and Atmel's developer tools. We are open source, bringing space to the people! Contact: Website and e-mail

A lot of documentation should exist on the Google Drive. Ideally, for CubeSat driver API documentation, check out the respective C files for each device - they should hopefully be well-commented.

1. Install Atmel Studio from Atmel's website.
2. Open the CubesatFreeRTOS.atsln file from the parent directory
3. Build the project in Atmel Studio

1. Acquire the arm-none-eabi-binutils, arm-none-eabi-gcc, arm-none-eabi-newlib packages. These provide the standard binutils (ld, objdump, objcopy, etc) along with compiler (gcc) and standard C library files.
2. Add the executables from the above step to your PATH. If you installed via package manager, you should be good to go.
3. Use the ./makelinux script to convert the Atmel Studio Makefile to a Unix-compatible version and build the executables.

1. Can run "Debug" from Atmel Studio, or can upload via Atmel Studio

This is a work in progress. Currently, openOCD seems to be the most viable solution. There is a config file for the SAM DXX boards (boards which use an ARM Cortex-M0+ processor) which may be what we need. Tentatively, the following may work:

  openocd -f target/at91samdXX.cfg

Then, in a separate terminal:

  telnet localhost 4444

Run the following within telnet:

  reset halt
  flash write_image erase <path to CubesatFreeRTOS.hex>
  reset run
