vnh5019 output voltage Issue

[topodom]

any possibility of using an oscilloscope on D9?

you should set the servo.speed.max to 100% for sure.

From there try using pypilot_control python script and you should be able to command 100% speed in both directions.


The motor.ino of only 1338 lines sounds very old

I don't have oscilloscope, only a multimeter. Here are may latest tests.
To make sure my analysis I'll try  on the latest moto.ino version the pypilot_control python script tonignt and post here.

22-APR-2020 moto.ino version

servo.speed.max default settings (50 % ?)
PMW is 2.29 V
the OUT A / OUT B  is 5.39
Result : the actuator is working, but it is very slow.


servo.speed.max = 100 %
PMW is 4.6 V
Power side :
the OUT A / OUT B  is 11.27 V
Result : the actuator is working, properly.


30-DEC-2020 moto.ino version

servo.speed.max  100 %
VDD : 5V
PWM signal is 0.5 V
Power side :
the OUT A / OUT B  is 2 V
Result : servo.speed.max does not have effect. The actuator is not working, of course.
