tsl230 sensor and frequency
Archiver
Posts: 46,084
Please help,
I just got a tsl230 light to frequency sensor from TAOS. I used the
example for the BSII (taosinc.com) and it uses the count command to
measure output. I got it to work. I am trying to understand the
results of exposing it to white,red,blue, and green led light. If
someone has read the data sheet please answer me a few questions.
1.) Does it measure light intensity or frequency the data sheet is
confusing?
2.) The count command gives me values that I am trying to convert to
frequency or wave length. I know the formula but I am not getting
any usable data from the stamp.
3.) should I use pulsein?
Thanks,
Curtis
