-# CMOCKA/CMAKE template
+# gy-521 Driver
 
-## Purporse
+The gy-521 module is usally interfaced with via TWI/I2C. The actual chip that
+is used in the module is the mpu6050 ic.
 
-- Streamline the setup of new C projects
-- Make it easy to setup a develoment enviroment
-- Allow TDD for embedded systems
-- Provide easy LSP usage via compile_commands.json
-- correctly use the CTEST command.
-- Avoid having to setup ruby/ceedling with it's dependency hell
+This driver doesn't make any assumptions about the platform it will run
+on beyond that it supports "stdlib.h" and "inttypes.h".
 
-## Organization
+The interface handles all the register and bitshift operations in the 
+the backgorund. The module uses getters and setters to abstract the
+actual data. This prevents the end user from trying to directly use the 
+structures data when it is volatile and may be setup to update in a ISR.

-The actual code is all stored inside the src direcotry with any libs/submodules
-stored inside their own subdirectories.
-
-The code we use to test stuff gets stored inside the dir "tests" in the 
-projects root.
-
-The compile_commands.json file in the project root is actaully a symlink to
-the generated compile_commands.json file inside the build directory. So if
-you notice your LSP isn't working correctly it probably means that you haven't
-ran cmake yet.

 ## Running and building the project
+The project uses CMake along with cmocka for unit testing.

-# Adding tests
-
-To actually add tests to the project create a new directory inside the
-"tests" dir. From there it will need a source.c and CMAKELists.txt file.
-
-You will also need to include it inside the tests/CMakeLists.txt file as well.

 ## RoadMap
 
-Things I want to add in the future:
-
-- Automatic module creation
-- template generation
-- header --> mocking
-- report generation
-- embedded specific scripts for common hardware items
