- smallerize 9mo agoI liked the overview and examples. But your program has no output?
- william1872 9mo agoGood observation! The shift is intentional - safety-critical code typically doesn't "output" in the printf sense. Instead it returns status codes and modifies state that the caller inspects. The pulse monitor example returns PULSE_OK/PULSE_ERR_* codes, and the caller queries state via pulse_status(). In a real system, that status feeds into a larger state machine or triggers hardware responses - not console output. That said, the c-from-scratch repo (https://github.com/SpeyTech/c-from-scratch https://github.com/SpeyTech/c-from-scratch) does include demo programs with actual output for learning purposes. The article focuses on the methodology shift rather than a complete runnable example. Fair point though - I could add a note about where to find working demos.
- smallerize 9mo agoI like the shift in emphasis to testing over just looking for output, but part of the point of a "hello world" program is to make sure the output is working. If it helps, you could frame it as debug output instead of a result. "Sending pulse...", "Received pulse!".
