41cc579488 + masking unused bits (less errors); 
+ refactored bits[] usage
 2014-10-15 07:48:27 +02:00
rob tillaart
fa681d5322 + reduced # micros calls 2->1 in inner loop. => footprint -18 
detection of the zero/one is doen by measuring the whole bit LOW+HIGH
+ improved wait for acknowledge
+ merged two loopCounters into one.
+ layout
+ dht22_test sketch collects statistics (every 20 reads)

e4ad65003b + replace digital read with faster (~3x) code 
=> smaller footprint
  => more robust for low MHz devices
