Sadly i ran into a new problem. The leds just flash one time and then stay off all the time.
With an example sketch from the fast led library (included in Teensyduino 1.22) the same happens.
With the newest fast led example sketch works fine….
but with the newest fast led library teensy runs out of flash memory.
“arm-none-eabi/bin/ld.exe: region `FLASH’ overflowed by 156 bytes arduino”
Can you help me out?
