* Atomic HRS reads (#1845)mark90642024-09-221-1/+2
| | | | | | | | | | - Combine the reading of all `HRS3300` registers into one I2C read so data is not partial - Downsizes both HRS and ALS to 16bit as the sensor does not generate larger than 16bit values in its current configuration - Increasing the resolution by 1 bit doubles the sensor acquisition time, since we are already at 10Hz we are never going to use a higher resolution - The PPG algorithm buffers for ALS/HRS are already 16bit anyway - Remove functions for setting gain / drive that are unused throughout the codebase - Calculate constants with constexpr
* Simplify ISR task wake checksmark90642024-03-121-4/+1
| | | | The macro checks the variable, so we don't need to check it ourselves
* Refactored Ppg for frequency based algorithm. (#1486)Ceimour2023-04-301-9/+26
| | | | | | | New implementation of the heart rate sensor data processing using a frequency based PPG algorithm. The HRS3300 settings are fine-tuned for better signal to noise at 10Hz. The measurement delay is now set to 100ms. Enable and use the ambient light sensor. FFT implementation based on ArduinoFFT (https://github.com/kosme/arduinoFFT, GPLv3.0).
* Update clang-tidy configuration and fix some warnings (#1474)Riku Isokoski2022-12-181-15/+20

* Update includes to to be relative to src directoryReinhold Gschweicher2021-11-151-1/+1
| | | | | | | Don't use relative imports like `../foo.h` as those depend on the relative position of both files. Rather than that use imports relative to the `src` directory, which explicitly is part of the include directories.
