In my opinion, when it comes to ultra low power, it is about code size and cycle counting. The KL05-SC samples are somewhat disappointing in this respect. For example they do not use the port PCOR and PSOR functions properly and they do not show how to make use of the BME module. Did i miss something? Does the processor expert do it better, or one of the development environments? I am looking for samples or proposals on using the BME in a systematic fashion. At least there should be a set of macros like those mentioned in the reference manual.
