This is an Arduino library for the TSL2561 digital luminosity sensors from Ams (Taos).

• It is modularized so you can use only what you need if space/ram is constrained.
• It does not swallow error codes so you can react on them.
• It doesn't use floats as they are overkill for most IoT stuff.

To use the library, just place the folder in your projects lib folder. For usage, see the examples folder.

The library has 3 classes: Tsl2561 All register access as described in the datasheet, except for interrupts Tsl2561Util Convenience functions like lux calculation or automatic gain Tsl2561Int TODO, Interrupt related stuff (not needed if int pin is not connected)

Tested with boards Nano, ESP8266 and ESP32 iArduino IDE and PlatformIO
