Objective | Add SD Card read/write capability to LOS |
Due date | Feb 27, 2023 |
Key outcomes | Design and implement an object-oritented structure to log arbitrary messages to a SPI-connect SD card |

NOTE: AS OF 23.01.31 EVERYTHING BELOW THIS LINE IS OUT OF DATE. CURRENTLY THE LOS_Logging + LOS_Storage thread on discord is the most updated. This page will be updated very very soon
Problem Statement
@Stanley TangHas written an SD card driver for communicating with an arbitrary SD card over SPI. This driver now needs to be ‘passed up’ the abstraction layer to an abstract interface with which ZP can call into it.

Timeline
Estimated timeline is ~1 month, as a conservative guess. This is @Darwin Clark 's first project, so there are many unknowns contingent on how long it takes him to grasp topics and organizational structures.
