| // fan_fake_pwm.c | |
| // | |
| // Purpose | |
| // Minimal-overhead "fake PWM" for a fan sysfs attribute that effectively supports | |
| // only two discrete values: 0 (OFF) and 255 (ON). | |
| // | |
| // Behaviour | |
| // 1) One-time screen check via Android system properties: | |
| // - If sys.screen.state == "off" OR debug.tracing.screen_brightness == "0.0", | |
| // the fan is forced OFF and the process exits. |

| * go (instead of VMIN) so that we only wake up once per MCU‐burst. | |
| * − Adds an “idle skip” mechanism: if the button state remains unchanged for | |
| * several consecutive packets, we skip the detailed per-packet parsing until | |
| * a new packet arrives or a threshold is reached. | |
| * − Performs a simple 50‐frame auto‐center calibration of both analog sticks | |
| * at startup. |
