Wrong PWM out of D5, changing Motor Pin Layout (video foto )

Post by IamTheVector »

Due to bad esc initialization , odd throttle management on D5 with ALL the motors/esc i have .. i decided to make some hard investigation using a diy oscilloscope to mesure the D5 output. Here is the result. Somehow the previous owner fried/corruptet the D5 output for PWM and now i cant use this output for esc use in fact, even if the pwm is generated, the calibration is impossible at that point. As you can see from the output the left pwm is the bad one, for all the others pin the pwm is the same as the right one.



Since every configuration uses pin5 i would like to know if i can use some software solution to override this hardware problem.

Before you ask, i allready reflashed esc , calibrated , uploaded the bootloader of the atmega, checked if the internal interrupt run fine, tryed the software on another atmega2560 ( it works on every pin ) and tried to put different esc's on different positions, i am sure , the only problem is d5 of the multiwii pro .
