Resolves: #26
In testing I did see the device get locked up when set to 10ms continuous read mode. For me it was hanging forever getting stuck inside of this loop when this happened. I tried a few ideas to make it sort of timeout if it gets stuck in that loop, but was unsuccessful with a few quick attempts.
Using 20ms instead seems to alleviate the problem, I have not had it lock up once on this setting. I believe this is what was being recommended by the comments in the issue.
This change enforces a 20ms minimum on for the continuous read setting.
