I used the WavePlayer sketch in the Audio Library and set it for AudioAnalogStereo. I then downloaded...
" I don't believe it" ..... I have just noticed that when compiling and uploading the CPU Speed was at 48 MHz .... I normally keep this at 96 MHz overclocked. So set it back to 96 and teensy now takes about 40 mA...
I have been trying the examples in Teensy library for Snooze deepSleep and hibernate. I get both to work as I think OK.
Before I started Teensy was taking about 45 mA when running small sketch eg blink and other...
