What this challenge is about.
Write a Linux Device Driver for a Custom Sensor Board. Advanced challenge in code. Writing production code that solves real engineering problems, earn a bloc...
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
