The sampling time of the ADC was too slow (239 ADC clock cycles), causing the reading of the next ADC channel to have cross talk as per issue #1261. Sampling time updated to 41 ADC clock cycles.

Make it clear that the name of the constant being defined is a string.
When the value being defined is also a string, use a new
DECL_CONSTANT_STR() macro.
