vnh5019 output voltage Issue

[topodom]

Thanks CapnKerln and Sean for your answers !

I have checked on my circuit :
VDD : 5V
INA/INB signals are 5 V
PWM signal is 0.5 V ?

Power side :
GND / VIN : 12V
OUT A / OUT B : 2V

You'r right ! I have tested out of the circuit. So when i send 5 V to the PMW then the VNH5019  is working properly and the actuator is moving !

I guess i did not set or touch the pmw settings?

Sean, you said "Maybe it will work if you reduce pwm frequency but it will then make audible noise"
Where can i set the pmw frequency ? in motor ino or on the configuration menu ?

I bought 3 and all 3 were defective in all different ways..  So I basically stopped using this part.   Maybe it will work if you reduce pwm frequency but it will then make audible noise.

I think you run into the same problem I describe in these posts. Solution is to go back to an earlier version of motor.ino. I have been using that version and the pwm_style == 2 for the last year. I have also tried to fix the 'audible noise' (is there any other ;-) ) but to no avail, and I've come to love the sound instead.

Actualy, i saw this post, but i am not confortable in reading the code. I don't understant exacly what have been change.
In an other hand, i'd like to use Sean code main branch, to be able to get improuvements in case of evolutions.
Anyway i'll try to see if the problem is the settled with previous code version.

I kept "pwm_style == 2" in moto.ino because in the comment it's said : "2 = vnh2sp30"
