Trying to get Fast-PWM to work on a Leonardo!? Is it only for Uno? Tips? C:\Users\KYLTON~1.MED\AppData\Local\Temp\xod\_temp\_sketchbooknRMBtu\xod\_1603636495269\_sketch\xod\_1603636495269\_sketch.ino:1225:17: note: suggested alternative: ‘fwrite’ pwmWrite(port, duty); ~~^~~~~~ fwrite Error during build: exit status 1 Compilation failed Command Process exited with code 1 The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers. ---
