DESIGN

\uD83E\uDD14 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.

🎯 Scope

Current Must Haves:

  • SD Card Non-Volitile storage via SPI

Future Expansion:

  • SD Card Non-Volitile storage via SDMMC

Not in scope:

Tasks Break Down:

\uD83D\uDDD3 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.
