servo library for Uno Wifi Rev2

[kock]

Hi,

Recently, I switched from Uno to Uno Wifi rev2. I use Servo library 1.1.3 working good with UNO but bad on Wifi Rev2.

My servo has jolts, random position jumps. I saw, using a scope, that pulses provided by UNO Wifi Rev2 are good 95% of time but bad 5% of time.

Switching back to UNO, pulses duration is constant.

An idea ?

Sketch is :

#include <Servo.h>

Servo my_servo;

void setup()
{
my_servo.attach(2, 550, 2250); // D2 pin used
Serial.begin(115200);
delay(10);
Serial.println(" ");
Serial.println("Uno_test");
}

void loop()
{
while (true)
{
mon_servo.write(1429);
delay(100);
}
}

I made test with Atmega328 emulation and none (Atmega4809) emulation : same issue.
