ALS31313_Pi

Read an ALS31313 3D Hall Effect Sensor - Designed for Raspberry Pi but should function fine for other SBCs

Reference: ALS31313 Datasheet

Usage Example:

$ ./als31313 -a 0x60 -b 1 -d 200

Options:

-a address (example: -a 0x65)

-b bus (Example, for /dev/i2c-1 use -b 1)

-d delay in ms (Example, to display temperature to STDOUT every 200 ms use -d 200) To display once and exit omit or set to 0.

-f filter value. Set the ALS31313's internal filter from 0 (none) to 7 (max)

-r resolution Set the ADC resolution. 0-3, where 0 is 18bit, and 3 is 12bit)

-q Suppress normal output, read temperature and exit returning the temperature (as integer)
