If you get compile errors for these functions, eitherchange to the prefered replacement function indicated in theerror message or set ALLOW_DEPRECATED_FUNCTIONS nonzero.A key change was to remove sd.init(spiRateID, chipSelect) in favor ofsd.begin(chipSelect, spiRateID). The difference between these two isthe order of the arguments which has caused serious confusion at times.
