- as Python 3.4 has problems on GHA we'll keep Travis for that while we still want to support 3.4

A Python library for accessing the VEML6070 digital UV light sensor from Vishay via
python-smbus using the I2C interface.
Default settings are suitable for Raspberry Pi 2 and 3 and was successfully tested using a breakout.
Not all functions of the chip are supported, especially not the interrupt handling since I had no use for this. Please send pull requests for improvements and bug fixes!
Serious Flaws before September 2019
In September 2019 it was discovered (and fixed) that:
- previously the sensor was never shutdown between measurements which wastes power but still takes measurements successfully
- the UVA light intensity was calculated wrongly (too high) for
rset != RSET_240Kdue to wrong compensation: higher
rsetleads to higher sampling time leads to higher absolute ADC step counts which should lead to every ADC step indicating a smaller amount of
W/(m*m)of UVA power and a higher precision of the final UVA power but it wrongly behaved the opposite way. The
integration_timeworked correctly all the time.
make help to find out about the available development commands.
