Question/Issue: I had a problem with the library, at this line. When I used continuous-mode example with the original library, it always returns error, so I tried to edit it a little bit. I changed return res; to return res ? 0 : 1; and it worked. And another problem is there are errors frequently, it usually keeps errors a while before returns values again. The logs: The original

Where did you expect to find the answer? I found Adafruit_BusIO library, although they edited library last 3 weeks, but it's about SPI. So, I don't know why these problems happened. Hope you find the answer soon.

THANKS!
