SD Card Parameters/Logger Architecture

• I/O text driver in boardfiles

• Logger and parametrization/config uses this driver

• I/O text driver assumes a folder/file structure, can implement this as see fit for non “file” type i/o text like swdio or flash memory

config controller: Lives in the non-board files so you can use c++ strings as long as you make sure that its not using the heap (LOOK INTO IT) or just use something else (immutable strings)

• has a private class member config table

  • an array of key value pairs (key, value, boolean representing if it requires a system restart on change)

• init function reads in values from sd card into config table

• update function takes key and value and upates the specific key

  • updates internal config table and I/O (only updates config table if I/O is successful

• read/get function that takes the enum value for the key and returns the value from the private config table

• could send signal to AM saying value changed

AM:

• in the beginning of it’s control loop

On startup:

• main.cpp inits SD card driver

• main.cpp

• main.cpp inits SM

• main.cpp leverages SM to get SD card parameters such that it can init all relevant managers

• main.cpp also creates drivers and queues and everything

runtime:

• SM
