The Brief

What you'll do, and what you'll demonstrate.

Write a Linux kernel driver for a custom SPI sensor board that exposes a clean hwmon interface and ships with a userland test program.

This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.

When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."

Earning criteria — what you'll demonstrate

  • Write a real Linux kernel module against the 6.x kernel API
  • Use sysfs and devicetree to expose hardware to userland cleanly
  • Handle SPI bus quirks (chip-select timing, byte ordering, calibration blocks)
  • Bridge kernel + userland in C with a defensible test program

Program Fit

Where this fits in your program.

Sharpens the same skills your degree expects you to demonstrate.

Strong alignment

This challenge maps to Imperative and Low-Level Programming at the Bachelor level. It sharpens the same practical skills your coursework expects — but in a real industry context with actual constraints and deliverables.
