| // 17 august 2016 | |
| // First version by Koepel. Public Domain. | |
| // Tested with Arduino Uno and Arduino.cc IDE 1.6.9 | |
| // In 2016, there are about 10 to 20 libraries for the BH1750, | |
| // but I was not happy with the existing code. | |
| // I started from scratch and tried to get the maximum out of the sensor. | |

| // HighWaterMark of the stack | |
| // ----------------------------------------- | |
| // Calculate the high water mark for a Arduino with AVR microcontroller. | |
| // It is the amount of memory that was never used since the Arduino was started. | |
| // | |
| // The __init() or .init1 up to .init9 was used in the past. | |
| // It was used to run assembly code to fill the unused ram with a pattern. | |
| // With Arduino 1.8.0 that did no longer work. | |
