I want use a servo in my Smart Farm Starter Kit.
In my script I "#include "ESP32_Servo.h".
Then I got the errot message
Arduino\libraries\ESP32_Servo\src\ESP32_Servo.cpp:144:9: error: 'ledcSetup' was not declared in this scope
I'm using the ESP32Servo library 3.0.6
Google told me to use a 2.x Version of this library. But I can't find it anywhere.
Exactly how did Google tell you this ?
What question did you ask ?
I asked
Arduino\libraries\ESP32_Servo\src\ESP32_Servo.cpp:144:9: error: 'ledcSetup' was not declared in this scope
I found: https://forum.arduino.cc/t/esp32-servo-library-error/1266962/5
The suggestion in the topic linked to was to revert to an earlier version of the ESP32 board files rather than an earlier version of the library files and it contains an explanation of how to do it
Hi,
Can you please post your code?
Thanks.. Tom.. 
OK. Where can I download "ESP32 board files" and can you tell me how to install they?
My code is simple:
#include "ESP32_Servo.h"
Servo myservo; // create servo object to control a servo
// 16 servo objects can be created on the ESP32
int pos = 0; // variable to store the servo position
// Recommended PWM GPIO pins on the ESP32 include 2,4,12-19,21-23,25-27,32-33
int servoPin = 26;
void setup() {
Serial.begin(9600);
myservo.attach(servoPin); // attaches the servo on pin 26 to the servo object
myservo.write(180);
delay(2000);
}
void loop() {
}
READ THE INSTRUCTIONS THAT I COPIED FROM THE OTHER TOPIC AND FOLLOW THEM
Can you send me the link to "THE OTHER TOPIC"?
Hi,
Where did you get the library files?
Thanks.. Tom...
Is this a wind up ?
You posted the link in post #3
I got the library files from https://fs.keyestudio.com/KS0567. Which send me to a dropbox archive with libraries.
What's the betting that both libraries use the ESP32 LEDC API, changes to which cause a problem
HI
ESP32Servo zip
Expands to
ESP32_Servo
Why can't they keep the same library names in zip and contents.
I got this error with ESP32 Dev MODULE board selected.
With sweep example code.

see http://www.arduino.cc/en/Tutorial/Sweep for a description of the original code
* Different servos require different pulse widths to vary servo angle, but the range is
* an approximately 500-2500 microsecond pulse every 20ms (50Hz). In general, hobbyist servos
* sweep 180 degrees, so the lowest number in the published range for a particular servo
* represents an angle of 0 degrees, the middle of the range represents 90 degrees, and the top
* of the range represents 180 degrees. So for example, if the range is 1000us to 2000us,
* 1000us would equal an angle of 0, 1500us would equal 90 degrees, and 2000us would equal 1800
* degrees.
*
* Circuit: (using an ESP32 Thing from Sparkfun)
* Servo motors have three wires: power, ground, and signal. The power wire is typically red,
* the ground wire is typically black or brown, and the signal wire is typically yellow,
* orange or white. Since the ESP32 can supply limited current at only 3.3V, and servos draw
* considerable power, we will connect servo power to the VBat pin of the ESP32 (located
* near the USB connector). THIS IS ONLY APPROPRIATE FOR SMALL SERVOS.
*
* We could also connect servo power to a separate external
* power source (as long as we connect all of the grounds (ESP32, servo, and external power).
* In this example, we just connect ESP32 ground to servo ground. The servo signal pins
* connect to any available GPIO pins on the ESP32 (in this example, we use pin 18.
*
* In this example, we assume a Tower Pro MG995 large servo connected to an external power source.
* The published min and max for this servo is 1000 and 2000, respectively, so the defaults are fine.
* These values actually drive the servos a little past 0 and 180, so
* if you are particular, adjust the min and max values to match your needs.

Tom..
Which version of the ESP32 board files are you using ?
I have now been able to solve my problem.
Thank you very much for your support and patience.
The solution in Esp32 Servo library error was helpful. Now I use ESP32 board version 2.0.17 .
Unfortunately, I had confused it with the library version. 
I am glad that you got there in the end
Hi,
That's good, and thanks for letting us know and ticking the solved square.
Tom..
