John Arne Birkeland 77fa51dcec ArduPPM v2.3.12 ATMega32u2 (APM 2.x) --------------------------------------------- - New improved fail-safe detection and handeling for single or multible signal loss and receiver malfuntion - Improved LED status for APM 2.x - Improved jitter performance (PPM output using nested interrupts) ------------------------------------------------------------- ARDUPPM OPERATIONAL DESCRIPTION ------------------------------------------------------------- APM 2.x LED STATUS: ------------------- RX - OFF = No input signal detected RX - SLOW TOGGLE = Input signal OK RX - FAST TOGGLE = Invalid input signal(s) detected RX - ON = Input signal(s) lost during flight and fail-safe activated TX - OFF = PPM output disabled TX - FAST TOGGLE = PPM output enabled TX - SLOW TOGGLE = PPM pass-trough mode SERVO INPUT (PWM) MODE: ----------------------- - PPM output will not be enabled unless a input signal has been detected and verified - Verified inputs are lost during operaton (lose servo wire or receiver malfunction): + The PPM output channel for the lost input will be set to the default fail-safe value + PPM throttle output (ch3) will be permanently set to fail-safe (900us) - Lost channel signal is restored: + PPM output for the restored channel will be updated with the valid signal + PPM throttle output (ch3) will not be restored, and will continue to output fail-safe (900us) PPM PASS-THROUGH MODE (signal pin 2&3 shorted): ----------------------------------------------- - PPM output will not be enabled unless a input signal has been detected - Active signal on input channel 1 has been detected: + Any input level changes will be passed directly to the PPM output (PPM pass-trough) + If no input level changes are detected withing 250ms: + PPM output is enabled and default fail-safe values for all eight channels transmitted + Input level change detected again, PPM fail-safe output is terminated and normal PPM pass-through operation is restored		2012-11-23 21:53:35 +01:00
