HI
i'm trying to use TSL2561 sensor, but i can't geting to work. I found the code that works on the psoc that, I change it so it fits nrf52840 but it still does not work, but works on the psoc
can anyone see what i have done wrong

i got it to work yesterday, but when i test to day it did not work and i have not change the code from yesterday.
