PWMServo library not uploading on UnoR4 Wifi

[adam-spen]

Description

The example code Sweep using #include will not upload on a Arduino Uno R4 Wifi

Any help would be greatly appreciated. I'm trying to use the board to drive 4 ESCs for a drone

Steps To Reproduce Problem

The code will upload to a Mega 2560 but it won't run.

Hardware & Software

Mega 2560 Uno R4 Wifi

Arduino Sketch

include

include

PWMServo myservo; // create servo object to control a servo

int pos = 0; // variable to store the servo position

void setup() { pinMode(9, OUTPUT); //myservo.attach(9); // attaches the servo on pin 9 to the servo object myservo.attach(9, 1000, 2000); // some motors need min/max setting }

void loop() { for(pos = 0; pos < 180; pos += 1) { // goes from 0 degrees to 180 degrees, 1 degree steps myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } for(pos = 180; pos>=1; pos-=1) { // goes from 180 degrees to 0 degrees myservo.write(pos); // tell servo to go to position in variable 'pos' delay(15); // waits 15ms for the servo to reach the position } }

Same problem!! Arduino UNO R4 Wifi and with Sweep.ino program extracted from the examples. is there a solution? is something missing?

[otaasa]

There is a conflict between two of the three 'begin' functions of the pwm.h library that are called from this other library. I have changed the name of the function that has two parameters, in the files pwm.h and pwm.cpp and with that, I can continue.
