It does enter the ISR (tested by turning on LED inside ISR), but when I use it in the main it doesn't change. The ISR reads a remote control receiver, so I can turn the LED on/of by moving a joystick on the TX. _________________________________________________________________ Send a smile, make someone laugh, have some fun!
