Can't set the sample rate :(

Get the sample rate 1:  None
Reference voltage:  1.242v 

Get the sample rate 2:  0x60f5
Get the sample rate 3:  0x60d5
Get the sample rate 4:  None

...... I cannot change the sample rate using any of the above methods. Seems to be stuck at about 220 SPS. Please help !!!!!!!!!

Looks like you stumbled upon a bug. I compared the code with the datasheet and found the sample rate config was 1-bit out. Should be fixed it in #12
